摘要
选择了一种毒性很高的氨基甲酸酯类农药——涕灭威和一种常用的阴离子表面活性剂——十二烷基苯磺酸钠(SDBS)组成复合污染体系,以细菌、真菌、放线菌、脲酶、过氧化氢酶和呼吸强度为土壤微生物生态毒理测试指标,研究了其对土壤微生物的联合作用。实验结果表明,涕灭威-SDBS复合污染体系对土壤微生物的影响存在着显著的交互作用,复合体系较二者单独作用的显著效应时间明显缩短,其机制是SDBS加速了涕灭威的降解解毒作用。
Interaction between aldicarb and sodium dodecylbenzenesulfonate(SDBS)on soil microbial ecotoxicological effects was evaluated in the present investigation. Six ecotoxicological parameters namely bacteria, actinomyces, fungi, urease, catalase and respiration were selected to illustrate the effects of aldicarb-SDBS combined pollution in soil. A significant interaction effect on soil microbe of aldicarb-SDBS combined pollution system has been shown by the experimental results. The combined action is antagonistic interaction, it may be explained by the following viewpoint that SDBS can help to increase degradation rate of aldicarb and the combined pollution system can remarkably shorten the action time in comparison with their single factor.
