Abstract: The contents of Cd,As,Hg and Pb of soil,irrigating water and rice corn in the irrigated areas of Anshan City irrigated with sewage water were investigated.The results showed that the contents of four kinds of heavy metal in the soil surface accorded with the national standard for the soil and environment quality generally.Impacted by the quality of irrigating water,the heavy metal contents of the soil and rice corn in the middle area were higher than that in the southern and northern areas,with the 1.08mg/kg Cd,1.03mg/kg Hg in soil and 0.2mg/kg Hg in rice corn respectively.These reached or were beyond the relative item of national standard for the soil and environment quality.The contents of heavy metals in soil and rice corn were obviously impacted by the irrigating water quality.It was suggested to avoid using the industrial sewage water as agricultural irrigation water directly.
