上海市部分居民家用水质处理器使用行为调查

Usage Behavior of Household Water Treatment Devices in Shanghai Residents

  • 摘要: 目的 了解上海市居民家用水质处理器(净水器)的使用情况和认知状况, 为指导居民合理使用净水器提供科学依据。

    方法 采用多阶段整群抽样方法, 选取320 户居民进行净水器使用及认知情况的问卷调查, 并用χ2 检验方法对数据进行分析。

    结果 居民净水器出水主要用于饮用(占93.8%, 300/320), 在使用超过2 年的净水器中有15.2%(30/197)的居民没有更换过净水器滤芯或滤膜, 使用不同类型净水器的居民直接饮用出水的构成比差异无统计学意义(P > 0.05); 91.3%(292/320)的居民不知道家中净水器的额定净水量, 近10%(29/320)的居民不认为滤芯或滤膜应定期更换, 34.4%(110/320)的居民误认为净水器可以除去自来水中的所有污染物。

    结论 居民对净水器的使用方法和知识存在误区, 有必要加强正确使用净水器的知识普及宣传教育工作, 引导正确使用净水器的行为, 降低净水器对居民的健康风险。

     

    Abstract: Objective To understand the usage behavior and knowledge regarding household water treatment devices (water filters) among residents in Shanghai, and to provide scientific evidence for guiding residents how to use household water filters properly.

    Methods By multistage and cluster sampling strategy, 320 residents were recruited and completed questionnaires on usage behavior and knowledge about household water filters. χ2 test was used to analyze data obtained from the questionnaires.

    Results Drinking water treatment was the main purpose of household water filters (93.8%, 300/320). Of the investigated households that had used water filters for more than 2 years, 15.2% (30/197) didn't replace strainer cores or filter membranes. There was no obvious difference in the proportions of directly drinking treated water among the residents using different types of water filters (P > 0.05). Regarding the knowledge of water filters, 91.3% (292/320) of the households didn't know the treating capacity of water filters they were using, nearly 10% (29/320) didn't think the strainer cores or filter membranes should be regularly replaced, and 34.4% (110/320) believed that all of the pollutants in the municipal supply water could be filtered by household water filters.

    Conclusion The residents investigated have misconceptions on the usage and knowledge of water filters. Therefore, it is necessary to strengthen public education on correct usage of water filters to reduce potential health risks.
