POLLUTION CHARACTERISATION AND RISK ASSESSMENT OF POLYCYCLIC AROMATIC HYDROCARBONS IN THE AQUACULTURE ENVIRONMENT
摘要
Abstract
Polycyclic aromatic hydrocarbons(PAHs),as a class of persistent organic pollutants(POPs),tend to accumu-late in organisms due to their lipophilic.Penaeus vannamei,widely cultivated in such settings,is particularly suscepti-ble to PAHs contamination,which may ultimately endanger human health.In this study,the contamination characteris-tics,ecological risks,and human health risks of 16 PAHs in a cultured water-biological system were investigated.Results showed that the total concentrations of the 16 PAHs(∑PAHs)in aquaculture water ranged from 44.62 to 350.46 ng/L,with Nap,Phe,BaA,Pyr,Chr,Flu,and Ace being the main pollutants.Pollution source analysis based on characteristic ratios showed that PAHs originated primarily from oil,coal combustion,and other biomass combustion.In shrimp muscle,the total concentrations of 16 PAHs ranged from 0.34 to 208.37 μg/kg(dry weight,dw),with 12 PAHs detected,and LMW PAHs predominated,while 5-and 6-ring PAHs accounted for minor proportions.The ILCR values associated with dietary exposure to shrimp ranged from 1.08×10-11-2.02×10-8,which was much lower than the USEPA standard value of 1×10-6,indicating negligible carcinogenic risk under current conditions.关键词
