Abstract:Aim at the seriously arsenic pollution in the soil,the paper discuses the environmental capacity of the arsenic, the environmental behavior of the arsenic and the effect on the crop. On the basis of analyzing arsenic's distribution and the main arsenide characters in soil. The source of arsenic and existing conformation are studied . At the same time,the infuences of arsenic pollution on crop growth and its accumulation law in the crop are investigated.The research bring forward three prevention and curing measures such as strictly prohibiting optional drainage, controlling arsenic pesticide usage quantity and fixing arsenic in the soil with lime.
Keywords:arsenic  arsenic of soil  soil  pollution
