大连付家庄海水浴场人体健康风险评估

于2015年7月31日至8月16日对大连付家庄海水浴场的肠球菌和粪大肠菌群进行连日监测，应用微生物定量风险评估的方法，得出2015年采样期间大连付家庄海水浴场男人、女人和儿童（＜15岁）患与肠球菌有关的胃肠道疾病的健康风险分别为1.78‰~43.31‰，1.19‰~30.03‰和2.37‰~55.55‰；患与粪大肠菌群有关的胃肠道疾病的健康风险分别为0.02‰~8.34‰，0.01‰~5.59‰和0.03‰~11.08‰。研究发现降雨对海水浴场水质影响显著，导致浴场水质变差，游泳者健康风险升高。根据本研究结果，推荐将肠球菌作为海水浴场监测的指标之一，以更合理评估海水浴场水质和人体健康风险。

Human health risk assessment of Dalian Fujiazhuang marine bathing beach

Enterococcus and fecal coliform in Fujiazhuang bathing beach, Dalian were monitored daily and continuously from July 31, 2015 to August 16, 2015, and quantitative microbial risk assessment was used for evaluation.The results were as follows.The health risk of men, women and children (under 15 years old) suffering from gastrointestinal diseases related with enterococci were 1.78‰~43.31‰, 1.19‰~30.03‰ and 2.37‰~55.55‰, respectively; the risk related with fecal coliform were 0.02‰~8.34‰, 0.01‰~5.59‰ and 0.03‰~11.08‰, respectively during the sampling period in 2015 at Fujiazhuang bathing beach, Dalian.Rainfall was found to impact the water quality of the bathing beach significantly, which resulted in the deterioration of beach water quality and increased swimmers' health risk.According to the results of this study, it is recommended that enterococci be regarded as one of the indicators for monitoring bathing beaches, to assess the water quality and human health risk more reasonably.
