Posted Thu Oct 30 2008: from Science: Farm chemicals can indirectly hammer frogs http://apocadocs.com/s.pl?1225385604 Atrazine, the second-most widely used agricultural pesticide in America, can pose a toxic double whammy to tadpoles. The weed killer not only increases the likelihood that massive concentrations of flatworms will thrive in the amphibians’ ponds, a new study reports, but also diminishes the ability of larval frogs to fight infection with these parasites. Moreover, the new data show, runoff of phosphate fertilizer into pond water can amplify atrazine’s toxicity. The fertilizer does this by boosting the production of algae on which snails feed. Those snails serve as a primary, if temporary, host for the parasitic flatworms, which can sicken frogs.
