目的了解河口区桶装饮用水的卫生状况以及存在的问题,为今后寻求更好的改进方法提供决策依据。方法2008年4月～11月,随机选取河口区18家企业的成品进行连续8个月的采样,进行分析。结果在检测的各项指标中,铅、砷、铜、霉菌和酵母菌计数、致病菌均合格,菌落总数、大肠菌群、亚硝酸盐、电导率项目存在不同程度的不合格现象。结论河口区桶装饮用水的卫生合格率较低,今后必须加强桶装饮用水生产企业的监督管理。
Objective To understand the hygienic status of barreled drinking water in estuarine areas and the existing problems so as to provide a basis for decision-making in the future to seek better ways to improve these methods. Methods From April 2008 to November 2008, samples of 18 enterprises in estuary area were randomly selected and sampled for continuous 8 months for analysis. Results Among the indexes tested, the counts of lead, arsenic, copper, mold and yeast were all qualified, and the total number of colony, coliforms, nitrites and conductivity items had different degrees of nonconformity. Conclusion The sanitation pass rate of barreled drinking water in the estuary area is relatively low, and the supervision and management of barreled drinking water producers must be strengthened in the future.
