Biomarkers response and population biological parameters in the earthworm Eisenia fetida after short term exposure to atrazine herbicide

Atrazine is one of the most used herbicides and its over-application in fields can affect the soils and their associated biota. In this work, earthworms (Eisenia fetida) were exposed to different concentrations of atrazine to assess possible sublethal harmful effects. In the search for reliable biom...
