Study documents dramatic regional decline of insect species
By Summit Voice
SUMMIT COUNTY — After studying ecosystems contaminated with pesticides, scientists say they’ve been able to measure a dramatic loss of invertebrate biodiversity in polluted streams and rivers.
The study is one of the first to document the toxic effects of pesticides at a regional ecosystem level, rather than exptrapolating toxicity from lab tests.
“The current practice of risk assessment is like driving blind on the motorway”, said ecotoxicologist Matthias Liess. “To date, the approval of pesticides has primarily been based on experimental work carried out in laboratories and artificial ecosystems.” Continue reading “Biodiversity: Even at ‘safe’ levels, pesticides are having catastrophic impacts on aquatic ecosystems”
