福建省近岸海域表层沉积物中的二噁英污染特征及生态风险评估
Contamination Characteristics and Ecological Risk Assessment of Dioxins in Surface Sediments of Nearshore Waters in Fujian Province

摘要: 自《新污染物治理行动方案》正式印发并实施以来，新污染物监测已然成为生态环境领域的新热点。本研究使用同位素稀释高分辨气相色谱-高分辨质谱对福建省近岸海域22个表层沉积物样品中的17种二噁英（polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans，PCDD/Fs）的含量进行检测，利用相关性分析和主成分分析法推断PCDD/Fs可能的污染来源，并运用毒性当量因子进行生态风险评估。结果表明，17种PCDD/Fs在福建省近岸海域表层沉积物中仅有1种未被检出，∑PCDD/Fs含量范围为58.7~3 980×10-3 ng·g-1（干质量），平均浓度为1 169×10-3 ng·g-1（干质量），浓度偏高区域主要集中在福州市的闽江口和厦门市的厦门湾附近海域。16种PCDD/Fs中含量最多的是毒性较小的八氯代二苯并对二噁英（octachlorodibenzo-p-dioxin，OCDD）。来源分析结果表明，福建省近岸海域表层沉积物中的二噁英可能主要来源于危废焚烧、交通排放和生活垃圾焚烧。生态风险评估结果显示，22个点位的毒性当量（toxic equivalents，TEQ）均处于较低风险水平。Abstract: Since the official issuance and implementation of the Action Plan for the Treatment of New Pollutants, monitoring of new pollutants has become a new hotspot in the field of ecological environment. In this study, isotope dilution high-resolution gas chromatography-high-resolution mass spectrometry (IRG-HRMS) was used to detect 17 dioxins (polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans, PCDD/Fs) in 22 surface sediment samples from nearshore waters of Fujian Province, correlation analysis and principal component analysis (PCA) were used to infer the possible sources of PCDD/Fs, and toxicity equivalence factors were applied for ecological risk assessment. The results show that only one congener of the 17 PCDD/Fs was not detected in the surface sediments of nearshore waters in Fujian Province, and the concentration of ∑PCDD/Fs ranged from 58.7 to 3 980×10-3 ng·g-1 dw (dry weight), with an average concentration of 1 169×10-3 ng·g-1 dw. The areas with high levels of PCDD/Fs were mainly concentrated in the waters near the Minjiang Estuary in Fuzhou City and Xiamen Bay in Xiamen City. The most abundant congener among the 16 PCDD/Fs detected was the less toxic octachlorodibenzo-p-dioxin (OCDD). The results of the source analyses indicated that PCDD/Fs in the surface sediments may mainly originate from hazardous and domestic waste incinerations and traffic emissions. The results of the ecological risk assessment showed that toxic equivalents (TEQ) at the 22 sampling sites are all at a low risk level.
