摘 要:目的了解昆明市地下水重金属指标的污染情况及地下水的质量情况。方法收集1982-2008年昆明市地下水的检测结果。对每年150件左右的地下水的九项重金属指标的合格率进行计算。结果1982-2008年昆明市地下水重金属指标中以铁锰超标为主。80年代和90年代初水样中铁的合格率相对90年代末和2002年以后低是因为以前地下水作为大量的饮用水源,而在后期集中式供水增多,封停了一些地下水井。昆明市地下水的质量有下降的趋势,尤其以西边较为明显。结论昆明市地下水的重金属指标有污染加重的趋势,地下水的质量也有下降的趋势。有关部门要加大监督力度,增加检测的频率和范围。政府应制定相应的政策,确保市民能喝上健康干净的地下水。Objective To know the pollution condition of heavy metals and the quality of groundwater in Kunming City. Methods The determination results of groundwater in Kunming City from 1982 to 2008 were collected. The eligible rates of nine kinds of heavy metals were detected from about 150 samples of groundwater in each year. Results Ferromanganese was the main heavy metal pollutant in groundwater of Kunming City from 1982 to 2008. That the eligible rates of iron from water samples in the 80's and early 90's were relatively lower than those of water samples in the late 90's and the years after 2002, was because of groundwater as most of the drinking water sources at the beginning, and later, centralized water supply was increased and some groundwater wells were sealed. The quality of underground water in Kunming showed a downward trend, particularly in the west of the city. Conclusions The heavy metal pollution of groundwater becomes more serious in Kunming City, and the quality of groundwater shows a declining tendency. Relevant departments should strengthen supervision and increase the frequency and scope of testing. It is necessary for the government to formulate policies and ensure clean and safe groundwater for the citizens.
