Abstract
Fenitrothion and aminocarb formulations were aerially sprayed over mixed coniferous forests near Fredericton and Bathurst, New Brunswick, Canada. Insecticide concentrations inside the spray blocks were measured at intervals of time by trapping the airborne toxicants in a fritted-glass bubbler containing dimethylformamide (DMF). The residues in DMF were analyzed by gas chromatography. Concentrations of the insecticides in the air decreased rapidly with time from peak levels of 1997 ng/m3 (fenitrothion) and 1201 ng/m3 (aminocarb). Concentrations of the 2 insecticides in the air samplers depended on the nature of the chemicals, type of formulation used, spray timings and other environmental factors.This publication has 1 reference indexed in Scilit:
