摘要
为进一步了解贵阳市土壤As的污染状况,采集贵阳市近郊12个乡镇蔬菜基地的64个土壤样本,测定贵阳市近郊菜地土壤As含量,并运用地质累积指数对菜地土壤As污染程度进行评价。结论：除湖潮乡和金华镇采样点的土壤As平均含量超过基线值外,其余采样点土壤中As的平均含量均未超过基线值。58个样本的地质累积指数小于0,4个样本的地质累积指数为0～1,2个样本的地质累积指数大于1。说明,贵阳市近郊蔬菜地土壤As污染状况总体上为无污染,但永乐乡、金华镇、湖潮乡和党武乡等个别地区存在无污染向中度污染变化的情况。
As content of 64 soil samples collected from vegetable bases of 12 villages and towns around suburbs of Guiyang was analyzed and then As pollution degree of vegetable soil was evaluated by geological accumulation index to further know soil As pollution status in Guiyang.Results：average As content of soil samples collected from 12 villages and towns is not above the baseline value except for Huchao Village and Jinhua Town.The geological accumulation index of 58 samples,4samples and 2samples is less than0.0～1and 〉1respectively,which indicates that As pollution status of vegetable soil around suburbs of Guiyang is non-pollution generally but As pollution status in some areas in Yongle Village,Jinhua Town,Huchao Village and Dangwu Village become from non-pollution to moderate pollution
