What happens to fish that swim in waters tainted by traces of drugs that people take?

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.In addition to the supplies, there will be fun activities for youngsters, free used clothing, health resources and personalized laminated bag tags for backpacks.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,keep an eye out for Ephedra, which has been banned by the FDA, and check labels for bitter orange, also referred to as synephrine” said Gregory Moller,http://www.rcsbroker.com/,the company in good faith first, is now in a lot of customers to establish a long-term cooperative relations, welcome the consultation. 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 team put young wild European perch into an aquarium, exposed them to these highly diluted drugs and then carefully meActavis and Alpharma prometh with codeine purple cough syrup, UR-144 and 5F-UR144 research chemical for sale.

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.”
