Characteristics of Heavy Metals in Jialing River Main Stream in Guangyuan City
摘要
Abstract
In order to explore the contamination degree of heavy metals in Jialing River main stream in Guangyuan City,the contents of heavy metals in surface water of Jialing River in Guangyuan City were analyzed respectively.The influence of temperature,pH and DO on the heavy metal (Pb,Cd,Cu,Zn) contents in water and the relationship between the heavy metal were explored.The results show that the contents of Cd,Pb,Zn and Cu decreased from 2012 to 2015 in general.The contents of Hg increased.The contents of heavy metals in dry season were lower than that of wet and normal season.In different seasons,the influence of pH,DO and temperature on the distribution of heavy metal contents in water varied.Significant positive correlations were found among these elements in surface water,which implied that these elements probably had common pollution sources.关键词
