Studies on the influences of lindane, pirimiphos, methyl, permethrin, zinc and dodecyl linear alkybenzene sulfonate LAS, on the activity and toxicity of cholinesterase ChE and glutathione s-transferase GST in Gammarus pulex L showed that only pirimiphos methyl caused a change in ChE activity in Gammarus with a significant reduction in enzyme activity after 24 h and 48 h exposure. Both lindane and permethrin caused a change in GST activity in Gammarus with a significant increase in enzyme activity after 48 h exposure. Lindane alos caused a significant increase in GST activity after 24 h exposure. Biomarkers ChE and GST were demonstrated a high degree of specificity and sensitivity in comparison to the lethality assay but GST activity was less specific than ChE activity.
