The content of pollutant of several vegetables and their soil and the quality of irrigating water were analyzed,the major elements measured were Hg,As,Cd,Cr,Cu,Mn,Ni,Pb, Zn,Se and Sn which inhibit plant growth, destruct soil ecosystem after plant and soil absorbed and accumulated these heavy metals and even affect people health after eating these vegetables, while the content of POBx and phenol were measured.The result showed that agricultural irrigating water has been polluted.In the farmland which is irrigated long time by the sewage,the content of noxious matter of soil and plants were higher,some heavy metals have evidently surpassed limited standard,soil has reached the level of severity pollution,the agricultural ecological environment and farmland ecosystem were inferior estate,the farm produces will probably form potential imperilment to people.In respect of the relation of soil pollution and vegetables, it is first reported on the relation between seed of Momordica charantia and pollutant, it is also first reported on Brassica juncea,Vigna sesquipedalis absorbing Sn etc..The research result even showed that the capacity of absorbing and accumulating noxious substance by seed is the strongest,and root is stronger then stem and leaf.
