The US Congress has passed legislation requiring the US Environmental Protection Agency
(US EPA) to develop, validate, and implement screening tests for identifying potential …

Nontarget aquatic insects are susceptible to chronic neonicotinoid insecticide exposure
during the early stages of development from repeated runoff events and prolonged …

Bridging the gap between early, sensitive responses to stress at the infra-organismal levels
and long-term, ecologically relevant responses at the supra-organismal levels is a …

Widespread agricultural use of neonicotinoid insecticides has resulted in frequent detection
of mixtures of these compounds in global surface waters. Recent evidence suggests that …

Direct and indirect ecological effects of the widely used insecticide bifenthrin on stream
ecosystems are largely unknown. To investigate such effects, a manipulative experiment …

The effect of 17α-ethinylestradiol (EE) and bisphenol A (BPA) on development and
reproduction in Chironomus riparius was determined over two generations in chronic …

The response of larval aquatic insects to stressors such as metals is used to assess the
ecological condition of streams worldwide. However, nearly all larval insects metamorphose …

Five benthic organisms commonly used for sediment toxicity testing were chronically (28 to
35 days) exposed to copper in standard laboratory-formulated sediment (following …

Few studies have determined the toxicity of perfluoralkyl substances (PFAS) to aquatic
invertebrates. We exposed Chironomus dilutus to 6 different PFAS to assess single …

Neonicotinoid insecticides are frequently detected in surface waters near agricultural areas,
leading to a potential for chronic exposure to sensitive aquatic species. The midge …
