摘要
采用五分法采集农灌水 (工业废水 )、农田土壤、农作物和畜禽产品样品 ,并检测其中重金属元素汞( Hg)、砷 ( As)、铬 ( Cr)和镉 ( Cd)的含量。结果表明 ,4种重金属元素在农灌水和土壤中的含量由低到高分别依次为Hg<Cd<As<Cr和 Cd<Hg<As<Cr,基本呈平行变化。 7种农作物对 4种重金属元素的吸收率有所不同 ,白菜、玉米、西红柿和豆角对 Hg、As、Cr和 Cd的吸收率较低 ,而菠菜和水稻对 Hg和 As、Cr的吸收率较高。此外 ,猪肉和鸡蛋中残留的 Hg和 As、Cr、Cd含量较低 ,而鸡、牛、羊肉中 Hg、Cd和
The samples of irrigating water for agriculture,farmland soil,crops and animal products were collected through the five divided method and were measured for the concentration of Hg,As,Cr and Cd.The results showed that the order of concentration of the four heavy metal elements in the water and soil was Hg<Cd<As<Cr and Cd<Hg<As<Cr,respectively.The absorptivity of seven crops for the four heavy elements was different.The absorptivity of Hg、As、Cr and Cd to Chinese cabbage,maize,tomato and beans was lower,and at the same time the absorptivity of As,Cr and Hg to rice and spinach was higher.Moreover,the concentration of As,Cr,Cd and Hg remained in pork and eggs was lower,and the concentration of Hg,Cd and Cr in chicken,beef and mutton was higher.
