G20 steps back from currency brink, heat off Japan

MOSCOW (Reuters) - The Group of 20 nations declared on Saturday there would be no currency war and deferred plans to set new debt-cutting targets, underlining broad concern about the fragile state of the world economy.

Japan's expansive policies, which have driven down the yen, escaped direct criticism in a statement thrashed out in Moscow by policymakers from the G20, which spans developed and emerging markets and accounts for 90 percent of the world economy.

Analysts said the yen, which has dropped 20 percent as a result of aggressive monetary and fiscal policies to reflate the Japanese economy, may now continue to fall.

"The market will take the G20 statement as an approval for what it has been doing -- selling of the yen," said Neil Mellor, currency strategist at Bank of New York Mellon in London. "No censure of Japan means they will be off to the money printing presses."

After late-night talks, finance ministers and central bankers agreed on wording closer than expected to a joint statement issued last Tuesday by the Group of Seven rich nations backing market-determined exchange rates.

A draft communiqué on Friday had steered clear of the G7's call for economic policy not to be targeted at exchange rates. But the final version included a G20 commitment to refrain from competitive devaluations and stated monetary policy would be directed only at price stability and growth.

"The mood quite clearly early on was that we needed desperately to avoid protectionist measures ... that mood permeated quite quickly," Canadian Finance Minister Jim Flaherty told reporters, adding that the wording of the G20 statement had been hardened up by the ministers.

As a result, it reflected a substantial, but not complete, endorsement of Tuesday's proclamation by the G7 nations - the United States, Japan, Britain, Canada, France, Germany and Italy.

As with the G7 intervention, Tokyo said it gave it a green light to pursue its policies unchecked.

"I have explained that (Prime Minister Shinzo) Abe's administration is doing its utmost to escape from deflation and we have gained a certain understanding," Finance Minister Taro Aso told reporters.

"We're confident that if Japan revives its own economy that would certainly affect the world economy as well. We gained understanding on this point."

Flaherty admitted it would be difficult to gauge if domestic policies were aimed at weakening currencies or not.

NO FISCAL TARGETS

The G20 also made a commitment to a credible medium-term fiscal strategy, but stopped short of setting specific goals as most delegations felt any economic recovery was too fragile.

The communiqué said risks to the world economy had receded but growth remained too weak and unemployment too high.

"A sustained effort is required to continue building a stronger economic and monetary union in the euro area and to resolve uncertainties related to the fiscal situation in the United States and Japan, as well as to boost domestic sources of growth in surplus economies," it said.

A debt-cutting pact struck in Toronto in 2010 will expire this year if leaders fail to agree to extend it at a G20 summit of leaders in St Petersburg in September.

The United States says it is on track to meet its Toronto pledge but argues that the pace of future fiscal consolidation must not snuff out demand. Germany and others are pressing for another round of binding debt targets.

"We had a broad consensus in the G20 that we will stick to the commitment to fulfill the Toronto goals," German Finance Minister Wolfgang Schaeuble said. "We do not have any interest in U.S.-bashing ... In St. Petersburg follow-up-goals will be decided."

The G20 put together a huge financial backstop to halt a market meltdown in 2009 but has failed to reach those heights since. At successive meetings, Germany has pressed the United States and others to do more to tackle their debts. Washington in turn has urged Berlin to do more to increase demand.

Backing in the communiqué for the use of domestic monetary policy to support economic recovery reflected the U.S. Federal Reserve's commitment to monetary stimulus through quantitative easing, or QE, to promote recovery and jobs.

QE entails large-scale bond buying -- $85 billion a month in the Fed's case -- that helps economic growth but has also unleashed destabilising capital flows into emerging markets.

A commitment to minimize such "negative spillovers" was an offsetting point in the text that China, fearful of asset bubbles and lost export competitiveness, highlighted.

"Major developed nations (should) pay attention to their monetary policy spillover," Vice Finance Minister Zhu Guangyao was quoted by state news agency Xinhua as saying in Moscow.

Russia, this year's chair of the G20, admitted the group had failed to reach agreement on medium-term budget deficit levels and expressed concern about ultra-loose policies that it and other emerging economies say could store up trouble for later.

On currencies, the G20 text reiterated its commitment last November, "to move more rapidly toward mores market-determined exchange rate systems and exchange rate flexibility to reflect underlying fundamentals, and avoid persistent exchange rate misalignments".

It said disorderly exchange rate movements and excess volatility in financial flows could harm economic and financial stability.

Karzai to Forbid His Forces to Request Foreign Airstrikes

KABUL, Afghanistan — President Hamid Karzai said Saturday that he would issue a decree forbidding his military forces from turning to NATO or American forces to conduct airstrikes, and he condemned the use of torture on detainees by his security forces.

He made his comments in a speech at the Afghan National Military Academy in Kabul. It was the first time he had dwelt at such length and with such passion on human rights.

His proposed ban on Afghan troops from calling in airstrikes came after a joint Afghan-NATO attack last week in Kunar Province, in eastern Afghanistan, that killed four women, one man and five children, all of them civilians, according to local officials.

Mr. Karzai said Gen. Joseph F. Dunford Jr., the commander of the international coalition forces fighting the Taliban and other insurgents in Afghanistan, told him that the airstrike had been requested by the National Directorate of Security, the country’s intelligence service. The attack took place in the Shigal district, an area where two known Taliban commanders were visiting family members, Afghan officials have said.

“Our N.D.S. in their own country calls foreigners to assist them and bombard four or five Al Qaeda or Taliban,” Mr. Karzai said.

“It is very regrettable to hear this,” he added. “You are representing Afghan pride. How do you call for an airstrike from foreigners on your people?”

Civilian casualties in the war on the Taliban has long vexed Mr. Karzai and has been a major point of contention with American and NATO troops. New rules instituted by commanders from the International Security Assistance Force have minimized the loss of life, and the coalition has all but stopped air attacks on populated areas and on homes. The result has been a dramatic drop in civilian casualties caused by foreign forces.

Nevertheless, Afghan troops, who lack their own air support, still turn to foreign forces for help during pitched battles with the Taliban and other insurgents. It was not clear whether there would be exceptions to Mr. Karzai’s decree, but he was clearly dismayed that his own forces would be employing the very techniques he had worked so hard to persuade the West to abandon.

In an unusual move, the Afghan president also publicly acknowledged that torture was a problem in Afghan detention centers and pledged to halt it. In the past, the government has largely deflected charges of torture raised by human rights organizations, contending that any abuse was the work of a few bad actors.

But after a United Nations report released in January detailed abuses or torture at a number of detention sites around the country, Mr. Karzai took a closer and more independent look at the complaints.

He appointed a delegation to investigate the report’s validity, and when the inquiry confirmed many of the allegations, he ordered the security ministries to implement the team’s recommendations. He reiterated that order on Saturday. The recommendations include prosecuting perpetrators of torture, giving detainees access to defense lawyers, providing medical treatment for detainees who are ill or have been beaten, and videotaping all interrogations.

“Not only have foreigners tormented and punished Afghans, but our people have been terrorized and punished by our own sons too,” Mr. Karzai said. “The U.N. report showed that even after 10 years, our people are tortured and mistreated in prisons.”

The United Nations’ human rights office here emphasized the importance of Mr. Karzai’s attention to the issue.

“It is encouraging that the president appears to be personally taking the issue of human rights of all Afghans seriously,” said Georgette Gagnon, the office’s director of human rights. She added that the government should act immediately on the delegation’s recommendations. “We urge them to do so without delay,” she said.

Alec Baldwin Is Ready to Tackle Full Time Daddy Duty

Mom & Babies
Celebrity Baby Blog

02/15/2013 at 09:00 AM ET

Mark Davis/WireImage

Dad-to-be Alec Baldwin certainly sympathizes with his expectant wife Hilaria — he’s experiencing all the aches and pregnancy pains too!

“My boobs hurt. My boobs are killing me, so sore,” the actor, 54, jokes with Extra. “My jeans don’t fit. My pants, I can’t buckle them.”

But, according to Alec, it’s Hilaria — due with the couple’s first child together late this summer — who has the crazy cravings.

“She was eating troughs of pineapple. I mean like tanker containers of pineapple,” he shares.

Quips Hilaria, “I didn’t eat pineapple before. It was bizarre. I really wanted pineapple.”

With the recent series finale of his award-winning show 30 Rock, Alec is excited to dive into daddy duty full time. “My dream is to be home with the baby, standing in the doorway, saying goodbye to Mommy,” he explains. “‘Mommy is going to work now. Bye Mommy … don’t work too hard!’”

While the newlyweds are still unsure of whether they’ll be welcoming a son or daughter, either way it looks like Alec, already dad to daughter Ireland, will eventually be juggling more than one baby.

“I want to have at least one of each, so whatever this is going to be, I want to have the next one [be the opposite sex],” says Hilaria.

States' choices set up national health experiment

WASHINGTON (AP) — President Barack Obama's health care overhaul is unfolding as a national experiment with American consumers as the guinea pigs: Who will do a better job getting uninsured people covered, the states or the feds?

The nation is about evenly split between states that decided by Friday's deadline they want a say in running new insurance markets and states that are defaulting to federal control because they don't want to participate in "Obamacare." That choice was left to state governments under the law: Establish the market or Washington will.

With some exceptions, states led by Democrats opted to set up their own markets, called exchanges, and Republican-led states declined.

Only months from the official launch, exchanges are supposed to make the mind-boggling task of buying health insurance more like shopping on Amazon.com or Travelocity. Millions of people who don't have employer coverage will flock to the new markets. Middle-class consumers will be able to buy private insurance, with government help to pay the premiums in most cases. Low-income people will be steered to safety net programs like Medicaid.

"It's an experiment between the feds and the states, and among the states themselves," said Robert Krughoff, president of Consumers' Checkbook, a nonprofit ratings group that has devised an online tool used by many federal workers to pick their health plans. Krughoff is skeptical that either the feds or the states have solved the technological challenge of making the purchase of health insurance as easy as selecting a travel-and-hotel package.

Whether or not the bugs get worked out, consumers will be able to start signing up Oct. 1 for coverage that takes effect Jan. 1. That's also when two other major provisions of the law kick in: the mandate that almost all Americans carry health insurance, and the rule that says insurers can no longer turn away people in poor health.

Barring last-minute switches that may not be revealed until next week, 23 states plus Washington, D.C., have opted to run their own markets or partner with the Obama administration to do so.

Twenty-six states are defaulting to the feds. But in several of those, Republican governors are trying to carve out some kind of role by negotiating with federal Health and Human Services Secretary Kathleen Sebelius. Utah's status is unclear. It received initial federal approval to run its own market, but appears to be reconsidering.

"It's healthy for the states to have various choices," said Ben Nelson, CEO of the National Association of Insurance Commissioners. "And there's no barrier to taking somebody else's ideas and making them work in your situation." A former U.S. senator from Nebraska, Nelson was one of several conservative Democrats who provided crucial votes to pass the overhaul.

States setting up their own exchanges are already taking different paths. Some will operate their markets much like major employers run their health plans, as "active purchasers" offering a limited choice of insurance carriers to drive better bargains. Others will open their markets to all insurers that meet basic standards, and let consumers decide.

Obama's Affordable Care Act remains politically divisive, but state insurance exchanges enjoy broad public support. Setting up a new market was central to former Republican presidential candidate Mitt Romney's health care overhaul as governor of Massachusetts. There, it's known as the Health Connector.

A recent AP poll found that Americans prefer to have states run the new markets by 63 percent to 32 percent. Among conservatives the margin was nearly 4-1 in favor of state control. But with some exceptions, including Idaho, Nevada and New Mexico, Republican-led states are maintaining a hands-off posture, meaning the federal government will step in.

"There is a sense of irony that it's the more conservative states" yielding to federal control, said Sandy Praeger, the Republican insurance commissioner in Kansas, a state declining to run its own exchange. First, she said, the law's opponents "put their money on the Supreme Court, then on the election. Now that it's a reality, we may see some movement."

They're not budging in Austin. "Texas is not interested in being a subcontractor to Obamacare," said Lucy Nashed, spokeswoman for Gov. Rick Perry, who remains opposed to mandates in the law.

In Kansas, Praeger supported a state-run exchange, but lost the political struggle to Gov. Sam Brownback. She says Kansans will be closely watching what happens in neighboring Colorado, where the state will run the market. She doubts that consumers in her state would relish dealing with a call center on the other side of the country. The federal exchange may have some local window-dressing but it's expected to function as a national program.

Christine Ferguson, director of the Rhode Island Health Benefits Exchange, says she expects to see a big shift to state control in the next few years. "Many of the states have just run out of time for a variety of reasons," said Ferguson. "I'd be surprised if in the longer run every state didn't want to have its own approach."

In some ways, the federal government has a head start on the states. It already operates the Medicare Plan Finder for health insurance and prescription plans that serve seniors, and the Federal Employees Health Benefits Program. Both have many of the features of the new insurance markets.

Administration officials are keeping mum about what the new federal exchange will look like, except that it will open on time and people in all 50 states will have the coverage they're entitled to by law.

Joel Ario, who oversaw planning for the health exchanges in the Obama administration, says "there's a rich dialogue going on" as to what the online shopping experience should look like. "To create a website like Amazon is a very complicated exercise," said Ario, now a consultant with Manatt Health Solutions.

He thinks consumers should be able to get one dollar figure for each plan that totals up all their expected costs for the year, including premiums, deductibles and copayments. Otherwise, scrolling through pages of insurance jargon online will be a sure turn-off.

After decent rally, perhaps time for a pause

NEW YORK (Reuters) - Stocks could struggle to extend their seven-week winning streak as the quarterly earnings period draws to a close and the market bumps into strong technical resistance.

Many analysts say the market could spend the next few weeks consolidating gains that have lifted the benchmark Standard & Poor's 500 <.spx> by 6.6 percent since the start of the year.

The S&P 500 ended up 0.1 percent for the week, recovering from a late sell-off on Friday after a Bloomberg report about slow February sales at Wal-Mart triggered a slide in the retailer's shares. It was the index's seventh week of gains.

Odds of a pullback are increasing, with the market in slightly overbought territory, said Bruce Zaro, chief technical strategist at Delta Global Asset Management in Boston.

"I do suspect the closing of the earnings season will lead to at least a pause and possibly a pullback," Zaro said. The S&P 500 could shave 3 to 5 percent between now and early April, he said.

Fourth-quarter earnings have mostly beaten expectations. Year-over-year profit growth for S&P 500 companies is now estimated at 5.6 percent, up from a January 1 forecast for 2.9 percent growth, and 70 percent of companies are exceeding analyst profit expectations, above the 62 percent long-term average, according to Thomson Reuters data.

On Thursday, Wal-Mart, the world's largest retailer, is due to report results, unofficially closing out the earnings period. Investors will be keen to see its quarterly numbers, especially after the Friday's news report that rattled investors.

The S&P 500 has gained 4.3 percent since Alcoa kicked off the earnings season on January 8.

The approaching March 1 deadline for across-the-board federal budget cuts unless Congress reaches a compromise adds another reason for caution, especially with recent economic data indicating the recovery remains bumpy.

Manufacturing output fell 0.4 percent last month, the Federal Reserve said on Friday, but production in November and December was much stronger than previously thought.

TESTING RESISTANCE

The S&P 500 has been trading near five-year highs, and it notched its highest level since November 2007 this week. But the gains have pushed the benchmark index almost as far as it is likely to go in the near term, with strong resistance hovering around 1,525 and 1,540, one analyst said.

As a result, the index is set to move sideways, said Dave Chojnacki, market technician at Street One Financial in Huntington Valley, Pennsylvania. "We just don't have the volume or the catalyst right now" to go above those levels, he said.

At the same time, other analysts say, the market has not shown significant signs of slowing, including a break below 15- and 30-day moving averages.

Such moves would be needed to show that momentum is slowing or that the market is at risk of a correction, said Todd Salamone, director of research for Schaeffer's Investment Research in Cincinnati, Ohio. The S&P 500's 14-day moving average is at 1,511 while the 30-day is at 1,494. The index closed Friday at 1,519.

Recent M&A activity, including news this week of a merger between American Airlines and US Airways Group , helped provide some strength for the market this week and optimism that more deals may be on the way.

In the coming days, the market will focus on minutes from the latest Federal Reserve meeting, due to be released on Wednesday, which could provide support if they suggest the Fed will remain on its current course of aggressive monetary easing.

The Fed minutes released in January spooked markets a bit when they revealed that some Fed officials thought it would be appropriate to consider ending asset purchases later in 2013. U.S. Treasury yields rose on that news, though market worries about a near-term end to quantitative easing have since faded.

Among other companies expected to report earnings next week are Nordstrom , Hewlett-Packard and Marriott International

Meteor Fragments Rain Down on Siberia; Hundreds of Injuries Reported

MOSCOW — Gym class came to a halt inside the Chelyabinsk Railway Institute, and students gathered around the window, gazing at the fat white contrail that arced its way across the morning sky. A missile? A comet? A few quiet moments passed. And then, with incredible force, the windows blew in.

The scenes from Chelyabinsk, rocked by an intense shock wave when a meteor hit the Earth’s atmosphere Friday morning, offer a glimpse of an apocalyptic scenario that many have walked through mentally, and Hollywood has popularized, but scientists say has never before injured so many people.

Students at the institute crammed through a staircase thickly blanketed with glass and from there out to the street, where hundreds of people were standing in awe, looking at the sky. The flash had come in blinding white, so bright that the vivid shadows of buildings slid swiftly and sickeningly across the ground. The light burst yellow, then orange. And then there was the sound of frightened, confused people.

Around 1,200 people, 200 of them children, were injured, mostly by glass that exploded into schools and workplaces, according to Russia’s Interior Ministry. Others suffered skull trauma and broken bones. No deaths were reported. A city administrator in Chelyabinsk said that more than a million square feet of glass had been shattered by the shock wave, leaving many buildings exposed to icy cold.

And as scientists tried to piece together the chain of events that led to Friday’s disaster — on the very day a small asteroid passed close to Earth — residents of Chelyabinsk were left to grapple with memories that seemed to belong in science fiction.

“I opened the window from surprise — there was such heat coming in, as if it were summer in the yard, and then I watched as the flash flew by and turned into a dot somewhere over the forest,” wrote Darya Frenn, a blogger. “And in several seconds there was an explosion of such force that the window flew in along with its frame, the monitor fell, and everything that was on the desk.”

“God forbid you should ever have to experience anything like this,” she wrote.

At 9 a.m., the sun had just risen on the Ural Mountains, which form a ridge between European Russia and the vast stretch of Siberia to the east. The area around Chelyabinsk is a constellation of defense-manufacturing cities, including some devoted to developing and producing nuclear weapons. The factory towns are separated by great expanses of uninhabited forest.

As residents of Chelyabinsk began their day on Friday, a 10-ton meteor around 10 feet in diameter was hurtling toward the earth at a speed of about 10 to 12 miles per second, experts from the Russian Academy of Sciences reported in a statement released Friday. Scientists believe the meteor exploded upon hitting the lower atmosphere and disintegrated at an altitude of about 20 to 30 miles above the Earth’s surface — not an especially unusual event, the statement said.

This meteor was unusual because its material was so hard — it may have been made of iron, the statement said — which allowed some small fragments, or meteorites, perhaps 5 percent of the meteor’s mass, to reach the Earth’s surface. Nothing similar has been recorded in Russian territory since 2002, the statement said.

Estimates of the meteor’s size varied considerably. Peter Brown, director of the Center for Planetary Science and Exploration at Canada’s Western University, said it was closer to 50 feet in diameter and probably weighed around 7,000 tons. He said the energy released by the explosion was equivalent to 300 kilotons of TNT, making it the largest recorded since the 1908 Tunguska explosion in Siberia, which is believed to have been caused by an asteroid.

Meteors typically cause sonic booms when they enter the Earth’s atmosphere, and the one that occurred over Chelyabinsk was forceful enough to shatter dishes and televisions in people’s homes. Car alarms were triggered for miles around, and the roof of a zinc factory partially collapsed. Video clips, uploaded by the hundreds starting early Friday morning, showed ordinary mornings interrupted by a blinding flash and the sound of shattering glass.

Maria Polyakova, 25, head of reception at the Park-City Hotel in Chelyabinsk, said it was the light that caught her eye.

“I saw a flash in the window, turned toward it and saw a burning cloud, which was surrounded by smoke and was going downward — it reminded me of what you see after an explosion,” she said. The blast that followed was forceful enough to shatter the heavy automatic glass doors on the hotel’s first floor, as well as many windows on the floor above, she said.

Valentina Nikolayeva, a teacher in Chelyabinsk, described it as “an unreal light” that filled all the classrooms on one side of School No. 15.

“It was a light which never happens in life, it happens probably only in the end of the world,” she said in a clip posted on a news portal, LifeNews.ru. She said she saw a vapor trail, like one that appears after an airplane, only dozens of times bigger. “The light was coming from there. Then the light went out and the trail began to change. The changes were taking place within it, like in the clouds, because of the wind. It began to shrink and then, a minute later, an explosion.”

“A shock wave,” she said. “It was not clear what it was but we were deafened at that moment. The window glass flew.”

The strange light had drawn many to the windows, the single most dangerous place to be. Tyoma Chebalkin, a student at Southern Urals State University, said that the shock wave traveled from the western side the city, and that anyone standing close to windows — security guards at their posts, for instance — was caught in a hail of broken glass.

He spoke to Vozhd.info, an online news portal, four hours after the explosion, when cellphones, which had been knocked out, were still out of order. He said that traffic was at a standstill in the city center, and that everyone he could see was trying to place calls. He said he saw no signs of panic.

In those strange hours, Ms. Frenn, the blogger, wrote down the thoughts that had raced through her mind — radiation, a plane crash, the beginning of a war — and noted that her extremities went numb while she was waiting to hear that the members of her family were unhurt.

When emergency officials announced that what had occurred was a meteor, what occurred to her was: It could happen again.

“I am at home, whole and alive,” she wrote. “I have gathered together my documents and clothes. And a carrier for the cats. Just in case.”

Viktor Klimenko contributed reporting from Moscow, Alan Cowell from London and Rick Gladstone from New York.

Study: Fish in drug-tainted water suffer reaction

BOSTON (AP) — What happens to fish that swim in waters tainted by traces of drugs that people take? When it's an anti-anxiety drug, they become hyper, anti-social and aggressive, a study found. They even get the munchies.

It may sound funny, but it could threaten the fish population and upset the delicate dynamics of the marine environment, scientists say.

The findings, published online Thursday in the journal Science, add to the mounting evidence that minuscule amounts of medicines in rivers and streams can alter the biology and behavior of fish and other marine animals.

"I think people are starting to understand that pharmaceuticals are environmental contaminants," said Dana Kolpin, a researcher for the U.S. Geological Survey who is familiar with the study.

Calling their results alarming, the Swedish researchers who did the study suspect the little drugged fish could become easier targets for bigger fish because they are more likely to venture alone into unfamiliar places.

"We know that in a predator-prey relation, increased boldness and activity combined with decreased sociality ... means you're going to be somebody's lunch quite soon," said Gregory Moller, a toxicologist at the University of Idaho and Washington State University. "It removes the natural balance."

Researchers around the world have been taking a close look at the effects of pharmaceuticals in extremely low concentrations, measured in parts per billion. Such drugs have turned up in waterways in Europe, the U.S. and elsewhere over the past decade.

They come mostly from humans and farm animals; the drugs pass through their bodies in unmetabolized form. These drug traces are then piped to water treatment plants, which are not designed to remove them from the cleaned water that flows back into streams and rivers.

The Associated Press first reported in 2008 that the drinking water of at least 51 million Americans carries low concentrations of many common drugs. The findings were based on questionnaires sent to water utilities, which reported the presence of antibiotics, sedatives, sex hormones and other drugs.

The news reports led to congressional hearings and legislation, more water testing and more public disclosure. To this day, though, there are no mandatory U.S. limits on pharmaceuticals in waterways.

The research team at Sweden's Umea University used minute concentrations of 2 parts per billion of the anti-anxiety drug oxazepam, similar to concentrations found in real waters. The drug belongs to a widely used class of medicines known as benzodiazepines that includes Valium and Librium.

The team put young wild European perch into an aquarium, exposed them to these highly diluted drugs and then carefully measured feeding, schooling, movement and hiding behavior. They found that drug-exposed fish moved more, fed more aggressively, hid less and tended to school less than unexposed fish. On average, the drugged fish were more than twice as active as the others, researcher Micael Jonsson said. The effects were more pronounced at higher drug concentrations.

"Our first thought is, this is like a person diagnosed with ADHD," said Jonsson, referring to attention deficit-hyperactivity disorder. "They become asocial and more active than they should be."

Tomas Brodin, another member of the research team, called the drug's environmental impact a global problem. "We find these concentrations or close to them all over the world, and it's quite possible or even probable that these behavioral effects are taking place as we speak," he said Thursday in Boston at the annual meeting of the American Association for the Advancement of Science.

Most previous research on trace drugs and marine life has focused on biological changes, such as male fish that take on female characteristics. However, a 2009 study found that tiny concentrations of antidepressants made fathead minnows more vulnerable to predators.

It is not clear exactly how long-term drug exposure, beyond the seven days in this study, would affect real fish in real rivers and streams. The Swedish researchers argue that the drug-induced changes could jeopardize populations of this sport and commercial fish, which lives in both fresh and brackish water.

Water toxins specialist Anne McElroy of Stony Brook University in New York agreed: "These lower chronic exposures that may alter things like animals' mating behavior or its ability to catch food or its ability to avoid being eaten — over time, that could really affect a population."

Another possibility, the researchers said, is that more aggressive feeding by the perch on zooplankton could reduce the numbers of these tiny creatures. Since zooplankton feed on algae, a drop in their numbers could allow algae to grow unchecked. That, in turn, could choke other marine life.

The Swedish team said it is highly unlikely people would be harmed by eating such drug-exposed fish. Jonsson said a person would have to eat 4 tons of perch to consume the equivalent of a single pill.

Researchers said more work is needed to develop better ways of removing drugs from water at treatment plants. They also said unused drugs should be brought to take-back programs where they exist, instead of being flushed down the toilet. And they called on pharmaceutical companies to work on "greener" drugs that degrade more easily.

Sandoz, one of three companies approved to sell oxazepam in the U.S., "shares society's desire to protect the environment and takes steps to minimize the environmental impact of its products over their life cycle," spokeswoman Julie Masow said in an emailed statement. She provided no details.
