Abstract: Determination of concentrations of the total and soluble forms of Fe,Mn,Cu,Pb,Zn,Cd,and Hg in some chemical fertilizers used in the country was conducted.The results showed that in the nitrogenous fertilizers and potash fertilizers,the content of heavy metals is relatively low while in the compound fertilizers and phosphorus fertilizer it is relatively high.In most of the chemical fertilizers,the contents of Cu,Pb,Zn,and Cd are controlled below the second grade standard for soil environmental quality and hence safe to use.But in some of the compound fertilizers and the nitrogenous fertilizer produced through sweetening with electron beam,the content of Hg well exceeded the standard,and Zn too.The use of these fertilizers,therefore,may have certain environmental risks.
