摘要对黄河上游兰州段2023年枯水期和丰水期水环境中短链氯化石蜡(SCCPs)的污染特征、来源和生态风险展开调查.研究区水相、悬浮颗粒相和沉积物中SCCPs浓度水平分别为116.04~1057.74ng/L、1.89~68.93 μg/g(干重)和121.65~428.97ng/g(干重).水相中SCCPs浓度丰水期高于枯水期,而悬浮颗粒相中SCCPs浓度枯水期则要高于丰水期,沉积物中SCCPs浓度在主要排污口下游以及河流较缓处枯水期高于丰水期,研究区可能存在丰水期排污量增加的情况;SCCPs同系物以C₁₀、C₁₁组分和Cl_5-7组分占比最高.研究区SCCPs污染可能主要源于CPs产品的生产和使用以及大气迁移传输,其污染贡献率分别为67.21%和32.79%.根据加拿大环境部的风险判定标准,研究区河水和沉积物中SCCPs污染暂未构成显著的生态风险,但悬浮颗粒相中SCCPs较高的浓度需得到应有的重视.

Abstract：This study investigated the pollution characteristics, sources and ecological risks of SCCPs in the water environment of Lanzhou section of the upper reaches of the Yellow River in 2023 during dry season and wet season. The concentrations of SCCPs in water phase, suspended particle phase and sediment in the study area were 116.04~1057.74ng/L, 1.89~68.93μg/g (dry weight) and 121.65~428.97ng/g (dry weight), respectively. The concentration of SCCPs in the water phase was higher during the wet period than during the dry period, but the concentration of SCCPs in the suspended particle phase was higher during the dry period; the concentration of SCCPs in the sediment was higher in the lower part of the main sewage outlet and the slower part of the river. The sewage discharge in the study area may have increased during the wet period. As to the homologue patterns of SCCPs, C₁₀, C₁₁ and Cl_5-7 components occupy the highest proportion. The SCCPs pollution in the study area may be mainly caused by the production and use of CPs products and atmospheric transport, whose pollution contribution rates were 67.21% and 32.79%, respectively. According to the risk assessment criteria of Environment Canada, SCCPs pollution in river water and sediment in the study area did not pose a significant ecological risk, but the high concentration of SCCPs in the suspended particulate phase needs to be paid due attention.
