Group: Male fish are producing eggs in our rivers.
A citizens' group has asked Congress to protect human health from contaminants that are causing male fish to produce eggs. The "intersex" condition is believed to be caused by chemicals that disrupt the endocrine system. Charleston State Journal, West Virginia. 19 November 2009.
Safe enough to eat?
The Department of Agriculture purchases hundreds of millions of pounds of pork, beef, corn and wheat to benefit agricultural interests. The result is sugary soda and greasy French fries, fish sticks, chicken nuggets, and pizza being fed to our school children for corporate profit. East Hampton Star, New York. Opinion, 13 November 2009.
Fish kills linked to water pollutants.
Since 2002 thousands of fish in the U.S. have died and continue to die in many rivers, most in the rivers of the southern east coast. And researchers have found what they call "the feminization of fish" or the presence of immature eggs in male fish. Scientists say both findings are related to contaminants in the water. Voice of America. 19 October 2009.
Southern fish experiencing identity crises.
Scientists have discovered estrogen in the water is making fish, particularly large-mouthed bass in the South, less aggressive. Turns out 70 to 90% of the bass in ponds across the Southeast have both male and female sex characteristics. Sacramento Bee, California. Opinion, 6 October 2009.
Gender-bending fish widespread in the U.S.
A survey of "feminization" of fish finds that a large percentage of male bass are producing egg cells. Scientists suspect this abnormal phenomenon is the result of synthetic chemicals in water that mimic the behavior of female hormones. All Things Considered, NPR. 17 September 2009.
Male bass in many U.S. rivers feminized, study finds.
Government scientists figure that one out of five male black bass in American river basins have egg cells growing inside their sexual organs, a sign of how widespread fish feminizing has become. Associated Press. 16 September 2009.
Male bass in many US rivers feminized, study finds.
Government scientists figure that one out of five male black bass in American river basins have egg cells growing inside their sexual organs, a sign of how widespread fish feminizing has become. Associated Press. 15 September 2009.
Gender-bending bass found in Yampa River.
Male bass in Colorado rivers and other basins around the nation widely exhibit feminine sex traits, a federal fish study released Monday shows. Denver Post, Colorado. 15 September 2009.
What is wrong with estrogen-mimicking hormones?
A host of common chemicals is feminizing males of every class of vertebrate animals, from fish to mammals, including humans. Collingwood Enterprise Bulletin, Ontario. 21 August 2009.
Fish produced fewer – or no eggs at all – after only one to two weeks of exposure to either of two different types of synthetic progestin hormones found in women's birth control and menopausal drugs.
The more potent of the pair of progestins also lowered sperm production and affected behavior in male fish. Effects occurred at levels found in the environment in sewage effluents. 30 July 2009. More...
UGa researchers study the reproductive effects of estrogens in rivers.
University of Georgia graduate student Kristen Kellock is working with UGa scientist Robert Bringolf to study how hormones and hormone-mimicking chemicals may be affecting the reproduction and development of fish in local rivers. Jacksonville Times-Union, Florida. 19 July 2009.
Oconee River pollution may be curbing fish reproduction.
Is something in the water turning fish in the Oconee River into sexual freaks - making male fish a little girly and impeding the ability of female fish to reproduce? Augusta Chronicle, Georgia. 17 July 2009.
Some horse estrogens used in hormone replacement therapies make their way from people to wastewater and into fish where they may contribute to the feminization of the animals, reports a study from England.
Laboratory tests showed the hormones – one of which was more potent than human varieties – can turn on estrogen hormone systems in fish at very low concentrations. This is the first time scientists report that HRT-related horse estrogens in water coming into and leaving sewage treatment plants are estrogenic in fish. 9 June 2009. More...
Study links estrogen exposure to fish kills, disease.
Exposure to estrogen puts fish at greater risk of disease and premature death, according to a new federal study. Greenwire. 5 June 2009.
Study suggests link between kills, intersex fish.
Some of the same pollutants that apparently cause male fish in the Potomac and Shenandoah rivers to exhibit female characteristics may also leave them vulnerable to disease and large-scale fish kills, according to a new study. Associated Press. 4 June 2009.
A British study shows that wastewater released from sewage treatment plants has a bigger impact than prior research suggests on egg production – and the long-term reproductive health – of fish living in the treated water.
This study was unique in that it looked at real effluents with their mixtures of different types and amounts of hormones. The authors showed that common methods used to assess the level of hormonal disruption may underestimate true reproductive impairment caused by estrogenic compounds. 1 May 2009. More...
Drugs in the water.
The drugs we take are showing up in our drinking water--and they’re showing up in fish. The federal government states that you should never flush drugs down the drain. But even if you want to do the right thing, it’s not always easy. Environment Report, Michigan. 21 April 2009.
In the mix.
Equine estrogens, presumably derived from human hormone replacement therapy medications, are pervasive in effluents from sewage treatment works. In both in vitro and in vivo studies, these compounds can have substantial effects on the reproductive systems of fish. Environmental Science & Technology. 3 April 2009.
Research using a powerful statistical model suggests that chemical mixes in wastewater feminize male fish.
Scientists in the United Kingdom report that more than one type of hormonally active chemical -- not just those that act like estrogen -- play a role in sex reversal of male fish. Anti-androgens also contribute. 2 March 2009. More...
Tumors and sex changes: a goby story.
It’s hard not to see the irony: A common chemical sometimes used in spermicides may be turning fish into hermaphrodites. San Luis Obispo New Times, California. 19 February 2009.
Water pollution feminizing fish.
Scientists already know estrogen from things like 'The Pill' is getting into the water and causing reproductive problems for fish. Now, a study finds there are other chemicals getting into water that might be messing with fish gender even more. Environment Report, Michigan. 16 February 2009.
Testosterone-blocking chemicals found in wastewater.
Testosterone-inhibiting chemicals appear to be finding their way into UK rivers, possibly helping to "feminize" male fish -- and raising questions about what the effects on human health might be, according to researchers. Reuters Health. 7 February 2009.
Sex-changing fish: Caused by contamination or nature?
After an ambitious study, researchers are still uncertain about how widespread endocrine disruption is in fish or even if it is occurring at all. Environmental Science & Technology. 15 January 2009.
Task force searching for source of fish kill.
Despite the release of a 2008 report connecting bacteria to the symptoms of the Shenandoah River fish kills, scientists will continue searching for an exact source. Strasburg Northern Virginia Daily, Virginia. 5 January 2009.
Antidepressants make for sad fish.
Overall, studies show that antidepressants can impair a fish’s ability to eat, to avoid being eaten — and perhaps even to attract a mate. Science News. 26 November 2008.
New program keeps drugs out of rivers.
A new consumer drug return program is one group's answer to the ongoing problem of poor fish health in the Potomac River and its tributaries. Charleston State Journal, West Virginia. 20 November 2008.
Something fishy.
It's a hot, hazy day on the Allegheny river near Pittsburgh. And this boat load of researchers is fishing for clues about the health of our rivers. So far samples of river bottom and fish are showing a stew of contaminants left behind by years of pollution from coal-burning plants. Medford KDRV TV, Oregon. 12 November 2008.
Bisphenol A restrictions.
Declaring that bisphenol A (BPA) potentially may harm infants and is toxic to fish, the Canadian government has unveiled a multipronged approach to restrict this widely used chemical. This will mark the first regulation of the compound anywhere in the world. Chemical & Engineering News. 24 October 2008.
Green chemistry: Real world solutions for real environmental problems.
Imagine if water could be free from chemical pollutants. You could eat fish, drink a glass of water, or gaze upon the beauty of an ocean without fretting over toxic contaminants. Given the global dimensions of water pollution today, this might seem like an impossible dream. But through green chemistry, we are making progress toward cleaner water. Nevertheless, substantial barriers exist to creating a world with safer, sustainable chemicals. Environmental Health News. Opinion, 14 September 2008.
A tale of two fish.
In the U.S., approximately one-quarter of the 70,000 chemicals in use have never been tested for toxicity, and every year the problem grows as new chemicals come onto the market. A growing number of researchers are using high speed methods on zebra fish. Environmental Science & Technology. 11 September 2008.
