中文摘要:
      为评价江苏典型斑点叉尾鮰养殖区多环芳烃(PAHs)残留水平和生态风险及健康风险,利用气相色谱-质谱联用仪(GCMS)根据生长阶段跟踪监测了江苏主要养殖区养殖塘斑点叉尾鮰鱼体、池塘水体和底泥中多环芳烃残留;采用Kalf风险商值法,进行池塘水体生态风险评价;利用沉积物质量基准法(SQGs)对池塘底泥开展生态风险评价;并用美国环保局(USEPA)推荐的健康风险评价模型对斑点叉尾鮰食用安全进行健康风险评价。在鱼体、养殖水体、底泥中,16种PAHs总检出率为100%,但致癌性物质苯并[a]芘均未检出,单体Nap、Phe、BaA、Pyr、Chr、Flu、Ace为常见检出物,其中Phe检出率达100%,Nap达到80%以上。结构组成上,鱼体、养殖水体均以2~4环为主要成分,底泥结构较为复杂,以3~4环为优势组分。鱼体中(以湿质量计)总PAHs含量范围在11.75~60.02 μg·kg-1,对食用斑点叉尾鮰引起的健康风险进行评价,成人的风险范围为2.25×10-9~5.80×10-7 a-1,致癌风险远小于最大可接受水平,处于致癌风险控制水平。池塘养殖水PAHs含量范围在0.03~0.46 μg·L-1,总体上生态风险程度为低风险,但单体Nap、Phe及部分池塘中Ace、Pyr及Fla处于中等风险水平,其他单体对生态系统的影响可以忽略。底泥(以干质量计) PAHs含量在24.48~145.04 μg·kg-1,总体上PAHs对生物毒副作用不显著。
英文摘要:
      The present study evaluated the residual levels of polycyclic aromatic hydrocarbons(PAHs) and their associated ecological and health risks in a typical channel catfish(Ictalurus punctatus) breeding area in Jiangsu Province. Gas chromatography-mass spectrometry (GC-MS) was used to track and monitor the PAHs residues in the fish bodies, pond water, and sediments from the main breeding ponds according to their growth stage in Jiangsu. The Kalf risk quotient(RQ) was used to assess the ecological risk of pond water, while sediment quality standards(SQGs) were used to assess the ecological risk of sediments. The health risk assessment model recommended by the United States Environmental Protection Agency(USEPA) was used to evaluate the health risk associated with eating channel catfish. The results showed that the total detection rate of 16 PAHs was 100% in fish bodies, pond water, and sediments. However, no carcinogenic substances, including benzo[a]pyrene, were detected. The PAHs monomers Nap, Phe, BaA, Pyr, Chr, Flu, and Ace were commonly detected in fish bodies, pond water, and sediments, and Phe was detected in all matrixes with a detection rate of 100%. The detection rate of Nap was more than 80%. In terms of structural composition of monomers, catfish and pond water normally contain compounds that have 2 to 4 rings, while the structure of monomers in sediments was more complex, with 3 to 4 rings being more dominant. The total PAHs content in the fish bodies(based on wet weight) ranged from 11.75 to 60.02 μg·kg-1. In addition, the concentration associated with the risk of eating channel catfish for adults was found to be 2.25×10-9~5.80×10-7 a-1. The carcinogenic risk was found to be far less than the maximum acceptable level, being at a controllable risk level. As for the ecological risk assessment of pond water, the concentration in pond water ranged from 0.03 to 0.46 μg·L-1. The overall ecological risk was low, but the individual Nap, Phe, Ace, Pyr, and Fla concentrations in some ponds were found to have medium risk levels. The impact of other monomers on the ecosystem was negligible. According to the ecological risk assessment of pond sediments, the concentration in sediments(calculated by dry weight) was 24.48~145.04 μg·kg-1. In general, the detected PAHs concentrations would not have significant side effects on organisms.
