| 英文摘要 | Mollusks, beyond their critical significance in aquaculture, have long been recognized as sentinel species for monitoring chemical contaminants in aquatic ecosystems. This study presents a comprehensive assessment of polycyclic aromatic hydrocarbons (PAHs) in an intensive coastal aquaculture area, encompassing their multimedia distribution, tissue-specific accumulation, bioaccumulation dynamics, partitioning behavior, and associated health risks. Among the 16 analyzed PAHs, 15 were detected in inshore seawater, while all 16 were quantified in intertidal sediment and mollusks. Low molecular weight PAHs were the most prevalent congeners. The average & sum;16PAHs were 235.2 ng L- 1 in inshore seawater and 124.8 ng g- 1 dry weight (dw) in intertidal sediment, while the levels reached 249.5 ng g- 1 dw in muscles and 608.9 ng g- 1 dw in viscera in mollusks. PAH concentrations were significantly higher in mollusk viscera than in muscles. Among inshore species, infauna bivalves accumulated more PAHs than attached bivalves and epifauna gastropods. Intertidal mollusks generally exhibited higher PAH levels than inshore species. The significant inverse linear correlation between log BSAF and log Kow of PAHs indicated reduced bioavailability of high-ring PAHs in mollusks. Estimated non-carcinogenic and carcinogenic risks remained well below safety thresholds, suggesting that the health risks of PAHs through mollusk consumption were within acceptable limits. Safety thresholds for daily intake of mollusks were established at 607 g for viscera and 1573 g for muscles, highlighting the need to limit viscera consumption. The findings emphasize the critical necessity of monitoring PAH accumulation in mollusks, given their major role in human dietary exposure to environmental contaminants. |
