Toxic impact of pesticides on bees has doubled, study shows

Analysis contradicts claims that the environmental impact of pesticides is falling, say scientists

“Compounds that are particularly toxic to vertebrates have been replaced by compounds with less vertebrate toxicity and that is indeed a success,” said Prof Ralf Schulz, of the University Koblenz and Landau in Germany, who led the research. “But at the same time, pesticides became more specific, and therefore, unfortunately, also more toxic to ‘non-target organisms’, like pollinators and aquatic invertebrates.”

Schulz said: “GM crops were introduced using the argument that they would reduce the dependency of agriculture on chemical pesticides. This is obviously not true if you look at toxicity levels.”
