A global study of pesticides in streams and waterways released Monday, April 13, found that such pollution is rare, but when found it exceeded regulatory limits about half the time. The study in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal, was based on a review of more than 800 studies conducted in 73 countries over the past 5 decades. "Overall, our analysis suggests that fundamental revisions of current regulatory procedures and pesticide application practices are needed to reverse the global environmental impacts of agrochemical-based high-intensity agriculture."
