市郊公路边农作物中重金属铅镉铜锌污染情况研究

The Research on Heavy Metals of Pb, Cd, Cu and Zn Contaminated in Crops along the Roadside of Suburb

为了考察市郊公路农作物重金属铅、镉、铜和锌的污染情况,本实验采集了潮州市郊意溪镇主要公路两侧农作物样品,并进行前处理和原子吸收分光光度计测定,结果显示,农作物中铅和锌含量均超过国家限量标准,污染较为严重,而镉和铜未超国家限量标准。从实验结果来看,意溪镇主要公路两侧农作物受铅和锌污染较为严重,不宜种植农作物,以避免农作物受铅和锌等重金属的污染,对人体健康造成危害。

In order to investigate the pollution of heavy metal Pb, Cd, Cu and Zn in crops on the suburbs of the suburbs, the experiment collected crop samples on both sides of the main highway in the suburb of Chaozhou, and carried out the pretreatment and determination. The results showed that the excess rate of lead and zinc in the crop was 100 %, respectively, The results show that the crops on both sides of the highway are not suitable for planting leaves vegetables, so as to avoid the pollution of heavy metals such as lead and zinc and harm to human health.
