摘要

本研究调查了尼日利亚河流州奥莫库奥拉希河（Orashi River）海产品，即螃蟹（C. sapidus）、软体动物（P. mollusca）、螯虾（Cambarus sp.）和虾（Caridea）中多环芳烃（PAHs）的含量。样品中的多环芳烃采用气相色谱-质谱法进行测定。多环芳烃同系物的相对含量没有变化。单个 PAHs 的平均浓度依次降低：D(a,h)ant > Pyr > Fluth > B(g,h,i)p > B(a)A > B(b)f > Ind (1,2, 3)pyr > B(a)pyr > Chr > B(k)flu > Ant > Flu > Phen > Aceth > Ace > Nap。蒽的多环芳烃含量最高，在 Caridea 中占 51.685%。所有海产品中 B(a)P、Ʃ2PAH、Ʃ4PAH、Ʃ8PAH 的 EDI 值均在欧洲食品安全局建议的最大允许限值范围内；这表明 PAHs 在人体系统中的累积量在允许水平之内。同样，这项研究得出的 PAHs 同系物的 HI 值也小于 1，这是美国环保局建议的安全限值。这项研究得出的 PAHs 同系物的总超额癌症风险超过了美国环保局建议的允许上限。这项研究表明，由于人们经常大量食用海产品，海水可能受到多环芳烃的污染，从而有可能导致非致癌和致癌风险。

Assessment of Polycyclic Aromatic Hydrocarbons (PAHs) in Seafood from Orashi River in Omoku, Rivers State of Nigeria and Human Health Risk Assessment

This study investigated the level of polycyclic aromatic hydrocarbons (PAHs) in seafood, namely, C. sapidus (Crab), P. mollusca (Mollusc), Cambarus sp. (Crayfish), Caridea (Shrimp) from Orashi River in Omoku, Rivers State of Nigeria. The PAHs in the samples were determined by gas chromatography–mass spectrometry. There was no variation in the relative level of PAHs congeners. The mean concentrations of individual PAHs decreased in the order: D(a,h)ant > Pyr > Fluth > B(g,h,i)p > B(a)A > B(b)f > Ind (1,2, 3)pyr > B(a)pyr > Chr > B(k)flu > Ant > Flu > Phen > Aceth > Ace > Nap. Anthracene contributed the highest PAHs values, with 51.685% in Caridea. The EDI values of B(a)P, Ʃ₂PAH, Ʃ₄PAH, Ʃ₈PAH across all the seafood were within the maximum permissible limit recommended by EFSA; this suggests that the accumulation of the PAHs in the body system are within the permitted levels. Similarly, the HI of the PAHs congeners obtained from this study were less than 1 which is the safe limit recommended by USEPA. The total Excess Cancer Risk of the PAHs congeners obtained from this study exceeded the permissible maximum limit recommended by USEPA. This study suggests that the water may be contaminated with PAHs which have the tendency to cause non-carcinogenic and carcinogenic risk because of frequent and high consumption of seafoods.

期刊介绍： The purpose of Polycyclic Aromatic Compounds is to provide an international and interdisciplinary forum for all aspects of research related to polycyclic aromatic compounds (PAC). Topics range from fundamental research in chemistry (including synthetic and theoretical chemistry) and physics (including astrophysics), as well as thermodynamics, spectroscopy, analytical methods, and biology to applied studies in environmental science, biochemistry, toxicology, and industry. Polycyclic Aromatic Compounds has an outstanding Editorial Board and offers a rapid and efficient peer review process, as well as a flexible open access policy.
