摘　　要：目的了解潮白河顺义段及汉石桥湿地水体中重金属的污染水平,为该地区再生水补水湿地的管理提供参考数据。方法在潮白河顺义段及汉石桥湿地分别选取采样点,于2021年4月(枯水期)和10月(丰水期)采集水样,对Zn、Cu、As、Pb、Cd、Cr这6种重金属元素进行定量分析,了解两处湿地水体中6种重金属元素的污染水平。结果两处湿地水体中6种重金属元素的浓度为0.06~9.72μg/L,均低于国家地表水Ⅲ类水质标准。枯水期各采样点水体中Zn、Cu和As浓度均高于丰水期(均P<0.05)。结论潮白河顺义段与汉石桥湿地水体中Zn、Cu、As、Pb、Cd、Cr这6种重金属元素的污染水平较低。Objective To understand the pollution levels of heavy metal elements in the water of Shunyi section on Chaobai River and Hanshi Bridge wetland,and provide scientific reference data for the management of reclaimed water and make-up wetland in the region.Methods The sampling points were set in Shunyi section of Chaobai River and Hanshi Bridge wetland,and the water samples were collected in April(wet season)and October(dry season)2021 respectively.Six kinds of heave metals(Zn,Cu,As,Pb,Cd,Cr)in the samples were quantitatively analysed with the developed methods,and the heavy metals polluted levels of the two wetlands were evaluated.Results The concentrations of six kinds of heavy metals in the reclaimed water wetlands were 0.06-9.72μg/L,which were lower than those of the national surface waterⅢwater quality standard.The concentrations of Zn,Cu and As in dry season were higher than that in wet season(all P<0.05).Conclusion The pollution levels of six kinds of heavy metals(Zn,Cu,As,Pb,Cd,Cr)in the water of Shunyi section on Chaobai River and Hanshi Bridge wetland were generally lower.
