Pyrethroids are a class of highly effective, broad-spectrum, less toxic, biodegradable
synthetic pesticides. However, despite the extremely wide application of pyrethroids, there …

The purpose of this review is to examine uses of carboxylesterase activity in environmental
monitoring with a specific emphasis on pyrethroid insecticides. The chapter begins with an …

While studies have documented the presence of pyrethroid insecticides at acutely toxic
concentrations in sediments, little quantitative data on sources exist. Urban runoff, municipal …

Exposure to arsenic-contaminated drinking water is a major threat to human health. Millions
of people across the world are exposed to arsenic-contaminated drinking water with …

Pesticides can enter surface waters via different routes, among which runoff driven by
precipitation or irrigation is the most important in terms of peak concentrations. The exposure …

Sediment plays a pivotal role in determining the physical, chemical and biological integrity of
aquatic ecosystems. A range of factors influences the impacts of sediment pressures on …

To detect effects of pesticides on non-target freshwater organisms the Species at risk
(SPEARpesticides) bioindicator based on biological traits was previously developed and …

The toxicity of single pesticides is likely underestimated when considering complex pesticide
mixtures found in agricultural runoff and this is especially true for newer pesticides with little …

This handbook provides a systematic description of the principles, procedures, and
technology of the modern analytical techniques used in the detection, extraction, clean up …

Contamination and toxicity associated with urban storm water runoff are a growing concern
because of the potential impacts on receiving systems. California water regulators are …
