四川省疾控机构饮用水水质检测能力调查

Water Quality Analysis Abilities of Centers of Disease Prevention and Control in Sichuan Province

目的掌握全省饮用水水质检测能力现状,为疾控机构(CDC)水质检测能力建设提供依据。方法各级疾控机构通过"国家饮用水水质卫生监测信息系统"上报水质检测能力,对指标可检测数和计量认证数由低到高进行3级评价。结果 21个市级疾控机构中,95.2%的机构常规指标检测能力和47.6%的机构非常规指标检测能力在3级;176个县级疾控机构中,66.5%的机构常规指标检测能力在3级,96.6%的机构非常规指标检测能力在1级。42项常规指标中,市、县级疾控机构的放射性指标可检测率、计量认证率都较低,同时部分毒理指标和消毒剂指标可检测率、计量认证率也低于80%;除省疾控中心外全省有9个疾控机构具备42项常规指标的检测能力,其中市级8个、县级1个。结论四川省疾控机构饮用水水质检测能力总体水平不高,与目前水质监测工作和《国务院关于进一步加强新时期爱国卫生工作的意见》中市级106项、县级常规指标的要求还有较大差距,各级政府应从保障饮水安全的角度加大对疾控机构的水质检测能力建设投入,保障饮用水水质卫生检测能力。

Objective To master water quality analysis abilities of CDCs at all levels in Sichuan Province and provide reference for ability construction. Methods Information about water quality analysis abilities was collected via the water quality monitoring information system,the number of items that can be detected and certificated was evaluated by 3 levels from low to high. Results Among 21 CDCs at the municipal level,abilities of 95. 2% to analyze routine items and of 47. 6% to analyze non- routine items were at level 3. Among 176 CDCs at the county level,abilities of 66. 5% to analyze routine items were at level 3 and of 99. 6% to analyze non- routine items were at level 1. In CDCs at municipal and county levels,the proportions of radioactive items that can be analyzed and have been certificated were low,and the proportions of part toxicological items and disinfectants items can be detected and have been certificated were less than 80% among the 42 routine items. Except the provincial CDC,nine CDCs,including eight at the municipal level and one at the county level,have the ability to analyze the 42 routine items. Conclusion The overall ability of CDCs in Sichuan Province to analyze drinking water quality is not high;there is still a large gap from the current requirement. Governments at all levels should increase the investment to CDC ability construction to improve the ability of water quality analysis.
