摘要

The relationship between soil biotoxicity and 10 heavy metals (Pb, Cd, Cu, Zn, Ni, Cr, Co, Sb, Fe, Mn) in an oilfield from China was investigated through multivariable analysis in SPSS. Multiple regression analysis was conducted to predict the toxicity of the 10 heavy metals after mitigating the multicollinearity among the metals by principal component analysis. Then, a multiple regression model was established to reveal the relationship of the biotoxicity and 10 heavy metals. It was found that the biotoxicity were significantly positive-correlated with contents of Zn, Ni, Cr, Sb, Fe, and Mn, but negative correlated with Cd, Co, Pb, and Cu. According to the multiple regression model, the contribution to biotoxicity of the heavy metals in soils was in the order of Cr>Ni>Mn>Sb>Zn>Fe, and a negative influence on the biotoxicity was caused by other 4 heavy metals, following the order of Cd, Co, Pb, and Cu.
