Environmental and biological effects following application of diazinon impregnated strips within a laboratory animal room.

Rats were exposed to diazinon impregnated strips in a conventional laboratory animal room. The air in the room was monitored for the pesticide. Erythrocyte acetylcholinesterase and plasma pseudocholinesterase activities were determined periodically. Air concentration of the pesticide never exceeded 1.34 microgram/m3. No significant change in enzyme activities were observed.
