黄埔口岸国际航行船舶生活饮用水水质调查

Investigation on the status of ship potable water at Huangpu port

目的了解黄埔口岸国际航行船舶生活饮用水水质卫生状况,调查船舶饮用水水质影响因素,为检验检疫执法和政策制定提供科学依据。方法参照GB/T 5750-2006生活饮用水标准检验方法,于2014年1月至2015年8月对黄埔口岸256艘次的国际航行船舶进行卫生监督并采集船舶生活饮用水进行金属指标、感官性状和物理指标、微生物指标、无机非金属指标及消毒剂指标检测,使用SPSS 22.0软件进行数据统计分析。结果 256份样品水质检测不合格率高达38.67%,不合格项目以菌落总数超标(30.1%)与铁含量超标(5.5%)为主。经统计分析,不同船舶类型和不同国籍的船舶水质合格率差异有统计学意义(P<0.05)。船舶船龄、吨位与船舶管理公司差异无统计学意义(P>0.05)。结论黄埔口岸国际航行船舶生活饮用水卫生情况不容乐观。

Objective To investigate the sanitary condition of potable water on international navigation ships at Huangpu port,explore what affects the quality of potable water on ships and provide constructive and feasible suggestions for quarantine policy formulation and law enforcement. Methods 256 water samples were collected on international navigation ships,and physicochemical and microbiological tests were conducted according to GB5750 Drinking Water Sanitation Standardized Testing. All data were analyzed by SPSS 22.0. Results The unqualified rate of potable water on international navigation ships reaches up to 38.67%,the unqualified item are mainly in total plate count（30.08%） and iron content（5.47%）. The pass percent of water quality was statistically significant difference with ship type and ship＇s nationality（P〈0.05）. Conclusion The sanitary condition of potable water on international navigation ships at Huangpu port was not optimistic.
