Abstract: A leaching experiment was adopted to study acid extracted heavy metals releasing in different soil. The result showed: With the pH dropping of simulated acid rain, the releasing intensity of acid extractable heavy metals obviously increase and the releasing amount of every heavy mental is negative correlation with pH. Zn is mainly released in pH 4.5~3.5; Cu is mainly released in pH 6.5~3.5, but the range of Cd is unsure; The releasing ranges of Cr and Pb, which are different in various soil. Moreover, the influence of acid extracted heavy metals releasing is obvious with different pH.
