Evaluation of heavy metal contamination in limestone soil from Suzhou area, Anhui province,China
The heavy metal elements analysis had been carried out for the limestone soils collected from Suzhou area,the degree of heavy metals pollution were evaluated by such methods as enrichment factor and geoaccumulation index,and the correlation and principal analysis of the testing results were studied based on SPSS.The results showed that the heavy metals of the samples can be subdivided into tow type:the Pb,Zn and Cr are below the first quality standard level,the Cu and As are between the first and second level of quality standard,the heavy metal element pollution degree were as follows:Cu>As>Cr>Zn>Pb>V.The V and Zr are controlled by the contamination of the detrital; the Pb,Sr and As are controlled by the source rock (limestone); the third factor contain the Zn,Cu and Al,which showed the effect by agriculture.
