In this present work, experiments were carried out to evaluate
the toxicity of pyrethroids in soil by measurement of the responses
of earthwormsE. fetidain soil exposed to deltamethrin and fenvalerate using endpoints at different levels, including the acute
and reproduction response combined with CYP3A4 enzyme activity. Our aims are: (1) to provide an insight into the long-team toxic
effects of pyrethroids on earthworms in soil; (2) to provide sound
data basis to warn of the potential risk brought by pyrethroids in
soil for a better risk assessment.
