| Abstract: | 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 w as Hg＜Cd＜As＜Cr and Cd＜Hg＜As＜Cr,respectively.The absorptivity of seven crop s for the four heavy elements was different.The absorptivity of Hg、As、Cr and C d to Chinese cabbage,maize,tomato and beans was lower,and at the same time the a bsorptivity of As,Cr and Hg to rice and spinach was higher.Moreover,the concentr ation of As,Cr,Cd and Hg remained in pork and eggs was lower,and the concentrati on of Hg,Cd and Cr in chicken,beef and mutton was higher. |
