2021-2023年济南市济阳区生活饮用水检测结果分析

Analysis of Testing Results for Drinking Water in Jiyang District,Jinan City From 2021 to 2023

目的分析2021—2023年济阳区城乡生活饮用水检测结果,系统了解饮用水卫生基本状况,为加强饮用水安全管理工作提供依据和技术支持。方法根据《济南市城乡饮用水水质监测工作方案》选择济南市济阳区内的8个街道(含乡镇)为监测镇,2021—2023年连续3年采集济南市济阳区内生活饮用水样本合计60份,检测其铁、锰、铜、锌含量,并加以分析。结果监测镇内生活饮用水中铁、锰、铜、锌含量2021年、2022年均在国家标准范围内,符合饮用水卫生标准。2022年铁、锰含量有升高趋势,但仍在标准限值内。2023年有2个监测点(10%)的铁含量超出限值范围(0.30 mg/L),分别为2023S008号0.370 mg/L与2023S0019号0.420 mg/L。结论监测点内生活饮用水未被锰、铜、锌污染,但铁含量逐年升高,可能存在风险,应引起重视。

Objective To analyze the results of urban and rural drinking water testing in Jiyang District from 2021 to 2023,systematically understand the basic hygiene status of drinking water,and provide basis and technical support for strengthening drinking water safety management.Methods According to the"Jinan Urban and Rural Drinking Water Quality Monitoring Work Plan",8 streets(including townships)in Jiyang district of Jinan city were selected as monitoring towns.From 2021 to 2023,a total of 60 domestic drinking water samples were collected in Jiyang district of Jinan city for three consecutive years,and iron,manganese,copper,and zinc contents were measured and analyzed.Results The content of iron,manganese,copper,and zinc in the monitored drinking water in the town was within the national standard range in 2021 and 2022,meeting the hygiene standards for drinking water.In 2022,the content of iron and manganese has an increasing trend,but it was still within the standard limit.In 2023,the iron content of two monitoring sites(10%)exceeded the limit range(0.30 mg/L),namely 0.370 mg/L for 2023S008 and 0.420 mg/L for 2023S0019.Conclusion The drinking water within the monitoring points has not been contaminated with manganese,copper and zinc,but the iron content has been increasing year by year,which may pose risks and should be taken seriously.
