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.

Activities of Acetylcholinesterase (AChE) in brain and erythrocytes, pseudocholinesterase (PChE) in plasma and non-specific carboxylesterase (NSE) in brain, liver, plasma and kidney were assayed at weekly intervals in growing male rats fed dietary pirimiphos-methyl at dosages of 1000, and 1500 ppm for a period of 28 days.

Also a significant reduction in blood cholinesterase activity was observed in both male and female rats fed on grain bound pirimiphos-methyl residues at two dose levels.

The obtained results are in parallel to that found in case of cholinesterase activity where the activity of both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) was declined at these seasonal period.
Chlorpyrifos, chlorpyrifos-methyl, malathion, diazinon, pirimiphos-methyl and profenofos were detected in most samples.

A dietary level of 7.5 ppm showed a significant decrease in serum cholinesterase activity and in lymphocytes and monocytes, and an increase in alkaline phosphatase activity and of urea nitrogen. 3.

Initial residues on the surface of cucumber, tomato and ornamental plants, and half-life periods for residue degradation are outlined for carbendazim, dimethoate, fenazox, malathion, methamidophos and pirimiphos-methyl.
Residues on plants, concentration in the air, dermal exposition, and inhibition of serum choline esterase activity are shown for methamidophos and aldicarb, respective reentry times being discussed.

Time-course inhibition pattern of both cholinesterase (ChE) and non-specific carboxylesterase (NSE) activities in brain and plasma revealed maximum inhibition at 24 h post-treatment which correlated well with the intensity of symptoms.
