2016年陕西省各级疾病预防控制机构饮用水水质检测能力调查分析

Investigation and analysis of drinking water quality testing capabilities of center for disease control and prevention at various levels in Shaanxi Province in 2016

目的了解2016年陕西省、市、县/区三级疾病预防控制机构(以下简称CDC)饮用水水质检测能力现状,为提升水质检测能力提供依据。方法按照2016年陕西省饮用水卫生检测工作方案,对全省各级CDC饮用水水质检测能力进行调查,通过"全国饮用水水质卫生检测信息系统"上报检测能力报告表。结果2016年陕西省各级CDC水质检测能力按省级、市级、县/区级逐级递减。省级CDC能够能检测104项指标,常规指标(42项)中市级、县/区级CDC平均能检测指标数分别为37项、26项,检测能力较弱的指标为部分消毒剂指标和消毒副产物指标、放射性指标;非常规指标(64项)中市级、县/区级CDC平均能检测指标数分别为4项、1项,可检测有效氯和氨氮的CDC相对较多,其余指标各市级、县/区级CDC检测能力很弱或基本不能检测。结论陕西省地市级、县/区级CDC水质检测能力总体偏弱,部分地区尚不能满足水质检测工作的需要,亟需从水质检测设施装备及人员配置等方面提升水质检测能力。

Objective To investgate the status of drinking water quality testing capabilities of the Center for Disease Control and Prevention(hereinafter referred to as CDC)at all levels in Shaanxi Province,so as to provide the basis for improving capability of water quality testing.Methods The capacity of testing water quality of CDCs at all levels in Shaanxi were investigated according to the 2016 Shaanxi drinking water hygiene testing work plan and the testing capability report form was reported through the"National Drinking Water Quality Sanitation Testing Information System".Results In 2016,the water quality testing ability of CDCs at all levels in Shaanxi Province were decreasing gradually in an order of provincial,municipal and county(district)levels.The provincial CDC can detect 104 indicators.The average detection capacity for the conventional indicators at municipal and county(district)levels ware 37 and 26 respectively,and the capacity for the disinfectant,by-products and radioactive detection in the routine category was lower.In the unconventional indicators(64 items),the average detection capacity at municipal and county(district)levels were 4 and 1 separately and the CDCs do not have the ability to detect other indicators except for ammonia nitrogen and effective chlorine.Conclusion The capacity of the testing water quality at the CDCs of municipal cities,counties(districts)in Shaanxi is generally scarce,and some areas still unable to meet the needs of water quality testing.Therefore,it is urgent to improve the water quality testing capability from the aspects of water quality testing facilities,equipment and staffing.
