摘　　要：目的初步掌握和了解宁海县所属象山港、三门湾海域生物性污染状况和各种贝壳类小海产品的卫生质量现状,为我县海产品安全风险评估,海水养殖业可持续发展战略提供可靠的科学依据。方法 4个监测区内设置6个点,定期采集海水、海涂泥及贝壳类小海产品进行检测。结果 2011年-2012年象山港、三门湾海水粪大肠菌群平均达标率分别为27.08%、61.46%。贝壳类小海产品粪大肠菌群合格率分别为16.67%、55.56%。副溶血性弧菌检出率分别为86.96%、91.30%。结论象山港、三门湾海域海水中粪大肠菌群达标率低,贝壳类海产品粪大肠菌群合格率较低、致病性弧菌检出率高,存在一定程度的生物性污染。Objective To understand and assess the biological pollution condition and the hygienic status,particularly the quality of various neritic shellfish products at Xiangshan Harbor and Sanmen Bay of Ninghai county.This information can provide reliable scientific basis for local seafood safety risk assessment and establish sustainable development strategy of marine aquaculture.Methods Seawater,tidal marsh mud and shellfish products samples were regularly collected from four monitoring stations including 6 monitoring points.Results During 2011 and 2012,the average qualification rate of fecal coliform in seawater of Xiangshan Harbor and Sanmen Bay were 27.08% and 61.46%,respectively.In neritic shellfish product,the qualification rate of fecal coliform in Xiangshan Harbor and Sanmen Bay were 16.67% and 55.56%,respectively;Vibrio parahaemolyticus detection rate in Xiangshan Harbor and Sanmen Bay were 86.96% and 91.30%,respectively.Conclusion The fecal coliform qualification rate in seawater and neritic shellfish products are much lower than health standard at Xiangshan Harbor and Sanmen Bay,in contrast,the pathogenicity Vibrio detection rate is high.Thus the biological pollution is serious in these areas.
