摘要
目的了解张家港市游泳池水水质的卫生状况,为制定有效的控制措施提供科学依据。方法对张家港市2015-2018年游泳池水水样p H值、浑浊度、尿素、游离性余氯、菌落总数和大肠菌群6项指标进行检测,并对检测结果进行统计学分析。结果2015-2018年共检测游泳池水水样771份,总合格率为73.02%。4年合格率呈上升趋势,且差异有统计学意义(P<0.001)。不同经营类型游泳池中酒店游泳池水水质合格率最高(87.50%),其次为社区和学校游泳池水水质的合格率,分别为76.10%和72.73%,社会经营性游泳池水水质合格率最低(69.03%),差异有统计学意义(P=0.002)。p H值、浑浊度、大肠菌群、菌落总数、尿素以及游离性余氯合格率分别为100.00%、100.00%、98.57%、96.24%、86.38%、85.47%。结论张家港市游泳池水水质总体合格率不高,不合格项目主要为尿素和游离性余氯,卫生行政部门应加强对游泳场所的监督管理和分类指导。
