| Abstract: | In order to make up a standard procedure for safe use of chlorpyrifos on soil, a field experiment was conducted to reveal the residue dynamics of chlorpyrifos in soil distributed in Changsha, Hangzhou and Jilin three places. The residues of chlorpyrifos in soil was determined by gas chromatography with ECD detector. The results showed that chlorpyrifos faster digestion in soil, digestion half-life of 3.39-5.42d, digestion rate consistent with a kinetic equation. |
