摘要：
The kinetics of pirimicarb photodegradation followed a first-order equation, in all studied solutions. Photolysis of pirimicarb was strongly increased in the presence of acetone, while methanol did not have any significant effect. The rate of degradation in the presence of natural river water was about 4.5 times slower than in distilled water. The half-life of pirimicarb in presence of different amount of dissolved humic and fulvic acids was about 2-10 times longer than in distilled water. The persistence of pirimicarb under aerobic conditions was greater than under anaerobic conditions.
