中文摘要:
      多环芳烃(PAHs)是一种由2个或者多个苯环组成的具有致癌性的有机污染物,广泛地存在于各种环境介质中。为了解上海金山区漕泾建国路某养殖虾塘内罗氏沼虾(Macrobrachium rosenbergii)体内多环芳烃的残留水平及食用风险,测定了采自2018年7—9月金山区罗氏沼虾体内16种PAHs的浓度,分析不同时期的累积特征并计算了其潜在食用风险。研究结果表明:除了ANY、ANA、DBA、IPY和BPF以外,其余的11种PAHs均有不同程度的检出,不同时期罗氏沼虾体内∑PAHs浓度范围为47.6~106 ng/g干重。PAHs优势组分为3,4环结构,其中4环占比最高,优势单体为ANT、BaA和CHR;溯源分析结果表明,研究池塘内PAHs主要是来源于燃烧源。采用美国环保署(USEPA)推荐的健康风险模型对食用罗氏沼虾引起的健康风险评价结果表明,金山区罗氏沼虾养殖虾塘PAHs致癌风险RILC值处于可接受水平,不会对消费者的人体健康产生影响。
英文摘要:
      Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic organic pollutants composed of two or more benzene rings and are widely present in various environmental media. In order to understand the health risk of PAHs in Macrobrachium rosenbergii (M.rosenbergii) in the culture ponds in Jianguo Road,Caojing Town,Jinshan District,Shanghai,16 PAHs collected from M.rosenbergii in Jinshan District from July to September 2018 were determined.Concentrations were analyzed for cumulative characteristics over time and their potential food risks were calculated.The results showed that except for ANY,ANA,DBA,IPY and BPF,the other 11 PAHs were detected in different degrees.The concentration of ∑PAHs in M.rosenbergii in different periods ranged 47.6-106 ng/g dw.The dominant components of PAHs were 3- or 4-ring structure,of which 4-ring compounds accounted for the highest proportion,and the dominant monomers were ANT,BaA and CHR.Traceability analysis showed that the PAHs in the pond are mainly derived from the combustion sources.Using the US Environmental Protection Agency's (USEPA) recommended health risk model to evaluate the health risks caused by the consumption of Macrobrachium rosenbergii,the ILCR value of PAHs in M. rosenbergii culture farms in Jinshan District was at an acceptable level and would not have impact on the human health.
