"American farmers are using smaller amounts of better targeted pesticides, but these are harming pollinators, aquatic insects and some plants far more than decades ago, a new study finds.
Toxicity levels have more than doubled since 2005 for important species, including honeybees, mayflies and buttercup flowers, as the country switched to a new generation of pesticides. But dangerous chemical levels in birds and mammals have plummeted at the same time, according to a paper in Thursday’s journal Science.
“The bottom line is that these pesticides, once believed to be relatively benign and so short-lived that they would not damage ecosystems, are anything but,” said Dr. Lynn Goldman, a former U.S. Environmental Protection Agency assistant administrator for toxic substances who wasn’t part of the study and is now dean of George Washington University’s school of public health."
