摘要
对广东省某研究区旧家电拆解集中区的土壤、水体、作物分别进行了采样测试,分别以各类国家标准进行了评价,结果表明该研究区的旧家电回收拆解对当地的生态环境造成了严重的破坏,水稻中已有有毒有害元素元素F和Ni超过了《食品中污染物限量(GB2762-2005)》所规定的上限,Hg和Cd也对当地的生态环境构成了严重的潜在威胁。
Soil ,water and crops were sampled and tested in a household appliance-discarding area of Guangdong Province, and also were evaluated according to the national standards, respectively. The results showed that human activities do much harm to the biological environment in this area. The concentrations of F and Ni in rice exceed the upper limit of food contaminants MRLs standards. Also, the concentrations of Hg and Cd also impose promotional threat to the local biological environment in the study area.
