2010年家用净水器零部件卫生状况调查

Sanitary quality sampling analysis of household water purifier parts in 2010

目的了解家用净水器零部件的卫生质量,为家用净水器的卫生监督管理提供依据。方法按照《卫生部涉及饮用水卫生安全产品检验规定》(2001),对2010年送检的家用净水器零部件进行卫生安全性检测。结果家用净水器水处理材料中活性炭滤芯(16.39%,20/122)和离子交换树脂(25.00%,10/40)的不合格率相对较高;输配水设备中端帽(20.83%,5/24)和密封圈垫(33.30%,4/12)不合格率相对较高。超标的项目主要包括TDS,氟化物,三氯甲烷,耗氧量、挥发酚、铅、砷、汞、镍、锌。结论活性炭滤芯、离子交换树脂、端帽和密封圈垫的卫生质量是制约家用净水器卫生质量的主要因素,应对其加强卫生监督管理。

Objective To analyze the main influencing factors of the health security and provide the basis for health supervision and management of household water purifier. Methods According to the relative national regulation, household water purifier parts were detected for health safety in 2010. Results The main failed factors of water treatment components in household water purifier were the carbon filter and ion exchange resin,unqualified rates of 16. 39% and 25.00% , respectively; the failed main factors of water distribution fittings were the end cap and seal pad ,unqualified rates of 20. 83% and 33.30%, respectively. The main unqualified factors included TDS, fluoride, chloroform, oxygen consumption, phenol, lead, arsenic, mercury nickel, and zinc. Conclusion The sanitary quality of carbon filter, ion exchange resin, the fat end cap and seal pad restricts the health security of household water purifiers, so the health supervision and management should be strengthened to the above -mentioned factors.
