Abstract：The contents of seven elements were determined in soil around the factory in Jinzhou by induct-ance coupling plasma atom emission spectrum ( ICP-OES) .A accurate analysis method was established for the determination of Cu、Cr、Pb、Mn、Ni、Cd、Zn in soil.The detect limits of all elements fit the demands of testing in this method .Seven kinds of elements had an excellent liner relationship in testing range .The relative standard deviations were in the range of 0.9%~4.2%.Recoveries of all elements were in the range of 87.8%~109.2%. The testing results exhibited that the content of Gd element was higher in agricultural land 500 meters away from the factory .It maybe caused by the pollution of the factory .The contents of else elements fit the values of agricul-tural land in Chinese Standard .
