We couple current findings of pesticides in surface and groundwater to the history of
pesticide usage, focusing on the potential contribution of legacy pesticides to the predicted …

We revealed a history of legacy pesticides in water and sediment samples from 19 small
streams across an agricultural landscape. Dominant legacy compounds included …

Aquatic organisms in streams are exposed to pesticide mixtures that vary in composition
over time in response to changes in flow conditions, pesticide inputs to the stream, and …

Pesticides impact invertebrate communities in freshwater ecosystems, leading to the loss of
biodiversity and ecosystem functions. One approach to reduce such effects is to maintain …

Insecticide use in urban areas results in the detection of these compounds in streams
following stormwater runoff at concentrations likely to cause toxicity for stream invertebrates …

Society is becoming increasingly aware of the value of healthy aquatic ecosystems as well
as the effects that man's activities have on those ecosystems. In recent years, many urban …

Agricultural pesticides continue to impair surface water ecosystems, although there are few
assessments of interactions with other modifications such as fine sediment and physical …

Pesticides pose a threat to the environment, but because of the substantial number of
compounds, a comprehensive assessment of pesticides and an evaluation of the risk that …

Transient, acutely toxic concentrations of pesticides in streams can go undetected by fixed-
interval sampling programs. Here we compare temporal patterns in occurrence of current …

The majority of central European streams are in poor ecological condition. Pesticide inputs
from terrestrial habitats present a key threat to sensitive insects in streams. Both …
