摘要 本研究以淮河淮南段水体为研究对象,采用电感耦合等离子体质谱法(ICP-MS)对水体中四种重金属Cu、Zn、Cd、Pb进行监测,结合综合性指标生化需氧量(BOD),探讨淮河淮南段的重金属含量变化规律和水质情况。研究结果表明,2017年度四个断面Cu浓度值波动较小,而Zn浓度值波动较大,与重金属Cd浓度值相比,Pb的浓度值波动幅度比较大,四个断面不同月份的BOD值波动较大,整体呈下降趋势,且都低于3 mg/L。由以上结果可知,2017年度四种重金属含量和BOD值均未超出地表水环境质量Ⅲ类水质标准(GB3838-2002)规定的限值,说明淮河淮南段水质质量较好。 In this study, four heavy metals including Cu, Zn, Cd, Pb, were monitored by inductively coupled plasma mass spectrometry(ICP-MS) in the Huainan part of the Huaihe River. Combined with the comprehensive indicator biochemical oxygen demand(BOD), the variation of heavy metal content and water quality in the Huainan part of the Huaihe River were discussed. The results showed that the concentration value of Cu in four parts fluctuated slightly, while that of Zn fluctuated greatly in 2017. Compared with the concentration of Cd, the concentration of Pb fluctuated greatly. The value of BOD in four parts fluctuated greatly among different months, showing a downward trend as a whole, and all of them were lower than 3 mg/L. It could be seen that in 2017, the content of four heavy metals and BOD value did not exceed the limit value specified in class Ⅲ of environmental quality standards for surface water(GB3838-2002), indicating that the water quality of Huainan part of Huaihe River was good.
