摘要
测定了巢湖合肥区底泥有机质、总氮、总磷、铅、镉、铬、汞和砷的含量 ,并研究了垂直分布特征。用潜在危害指数法对底泥污染作了评价。对有机质与其他污染物之间的关系作了相关分析。其中有机质与总氮之间的线性相关方程为 :y =0 0 676x +0 0 95 2 ,相关系数 0 986,线性高度显著。
Organic content, total nitrogen, total phosphorus, lead, cadmium, chro mium, mercury and arsenic in the sediments of Chaohu Lake are investigated. The vertical distributions of pollutants in sediment are discussed. The potential ec ologic risk index is used to evaluate metal pollution in sediment of Chaohu Lake . The correlative characteristics between organic content and other pollutants a re analyzed. The linear equation between organic contents and total nitrogen is y0.0676x+0.0952 with 0.985 of correlation coefficient.
