摘要
目前中国仍在生产滴滴涕(DDT),并以其为原料生产三氯杀螨醇作为杀虫剂使用。为评价淘汰DDT对于中国生态环境的影响,采用情景分析的方法,估算了在采取不同的淘汰策略下土壤中DDT残留浓度的变化,以此来评价淘汰DDT的环境影响。与基线情景相比,三种控制情景下DDT的累积生产量都有不同程度的减少,相应土壤中的残留浓度也有不同的下降,且淘汰的速度越快土壤中DDT浓度下降的幅度越大。
The scenarios analysis was used to estimate the environmental effect of phasing out DDT in China. The DDT residue concentration of soil was simulated under the different strategy of phasing out. Comparing with the baseline, the accumulative output of DDT and the residue concentration of soil were decreased under the other three controlled scenarios, and the faster DDT was phased out, the more concentration of soil was reduced.
