Study: Combining pesticides makes them more deadly for fish http://apocadocs.com/s.pl?1236101085
Common agricultural pesticides that attack the nervous systems of salmon can turn more deadly when they combine with other pesticides, researchers have found.
Scientists from the NOAA Fisheries Service and Washington State University were expecting that the harmful effects would add up as they accumulated in the water. They were surprised to find a deadly synergy occurred with some combinations, which made the mix more harmful and at lower levels of exposure than the sum of the parts.
The study looked at five common pesticides: diazinon, malathion, chlorpyrifos, carbaryl and carbofuran, all of which suppress an enzyme necessary for nerves to function properly.
The findings suggest that the current practice of testing pesticides - one at a time to see how much is needed to kill a fish - fails to show the true risks, especially for fish protected by the Endangered Species Act, the authors concluded in the study published Monday in the journal Environmental Health Perspectives.
