-
摘要:
目的 综合评价浦东新区自动售水机出水水质,分析自动售水机水质卫生状况,以保障自动售水机饮用水卫生安全。 方法 以上海市浦东新区辖区内自动售水机为对象(共1 100台),随机抽检110台,运用饮用水水质指数(DWQI)法对检测结果进行综合评价分析。 结果 所抽检的110台自动售水机中,"水质较差"的占46.36%;其次是"水质良好"的占36.36%;"水质差"的占16.36%;"水质很差"的占0.90%;无"水质优良"的自动售水机。 结论 运用DWQI法对自动售水机水质进行评价,能够综合反映自动售水机水质优劣,方法操作简单且具有实用性。本次研究显示,目前浦东新区自动售水机水质现况不容乐观,政府及卫生部门应加强监督与管理,督促自动售水机经营单位规范经营。 Abstract:Objective To evaluate water quality in automatic water vending machines in Pudong New Area of Shanghai, and to investigate their sanitary status and so as to ensure the safety of drinking water. Methods A total of 110 out of 1 100 automatic water vending machines were randomly selected and inspected using drinking water quality index (DWQI). Results Among the 110 machines detected, 46.36%, 36.36%, 16.36%, 0.90% and 0.00% were respectively rated "marginal", "good", "poor", "very poor" and "excellent" in water quality. Conclusion DWQI is a practical and rapid method to evaluate the water quality in automatic water vending machines. This study highlights that the water quality from automatic vendor machines in Pudong New Area of Shanghai needs to be improved. Both the government and the public health department should enforce the surveillance of water vendors.
