Pollution distribution and source analysis of heavy metals in the groundwater of the Baotou City
摘要
Abstract
In order to investigate the groundw ater quality and cont amination in Baotou City, 33 groundwater samples and 4 sur-face w ater samples were collected to analyze the heavy met als such as Cr, Cd, Hg, Pb, and As. The pollut ion dist ribution of heavy metals and their sources in four different dist ricts in Baotou w ere analyzed using the hydrochemical analysis, environmen-tal geochemical analysis, environmental qualit y assessment , and pollution evaluation methods. The result s indicated that all four districts have heavy metal contamination and the heaviest pollution is detected in the Donghe district, w here the samples with detection and over standard of heavy metals are the most. The order of detection rate of heavy metals is Pb> As>Cd> Cr6+ , and the pollution degree is Pb> Cr6+ > As> Cd. Based on the analysis of indust rial wastewat er, heavy met al contents in soil and domestic sew age, industrial w astew ater effluent is the main source of heavy metal pollut ion. In addition, there is significant rela-tionship betw een Cd and Pb, indicating that they may be f rom the same pollut ion source.关键词
