Concentration and Distribution of Organic Pollutants in Fish of Yongxing and Qilianyu Islands,Xisha,China
Organic pollutants were widely detected in marine fish in global oceans,and long-term consumption can pose certain health risks to humans.To study the pollution characteristics,50 fish were collected in Xisha,China,in which Organochlorine pesticides(OCPs),polycyclic aromatic hydrocarbons(PAHs)and polychlorinated biphenyls(PCBs)were determined by GC-MS.It was found that OCPs,PAHs and PCBs concentrations in fish ranged from 2.23-91.57ng/g ww,2.11-31.70ng/g ww and 1.55-54.04ng/g ww,respectively.The ratios of DDTs/(DDE+DDD)>1 in 50%of fish.The ratio of ANT/(ANT+PHE)>0.1 in 88%of fish and the ratio of FL/(FL+PYR)>0.5 in 100%of fish.Using the ILCR model to evaluate the ecological risk of fish,the ILCR values of organic pollutants in most fish were below 1×10-6.The BRIEF REPORT is available for this paper at http://www.ykcs.ac.cn/en/article/doi/10.15898/j.ykcs.202304280057.
