UV absorbing compounds are of emerging concern due to their large production volumes, their persistence or pseudo-persistence, and their potential adverse effects. This is the first study investigating the environmental occurrence and potential hazard of organic UV stabilizers and UV filters in the North and Baltic Sea surface sediments, including the connecting Skagerrak and Kattegat straits. In total, nineteen substances were identified over the entire study area, including the rarely studied compounds ethylhexyl triazone (EHT) and bisoctrizole (UV-360). Octocrylene (OC) was the predominant compound in this study with regard to detection frequency (79%) and concentrations (up to 9.7 ng/g dw). OC accounted for more than 65% of UV stabilizer contamination in the German Bight. The triazine derivative EHT was quantified in the Rhine-Meuse-Delta and the German Bight in concentrations up to 2.0 ng/g dw. In the Baltic Sea, benzotriazole UV stabilizers accounted for 60% of the contamination, with UV-360 as the main substance. The estimated environmental hazard quotients indicated a negligible impact on benthic and sediment-dwelling organisms in the North and Baltic Seas. Region-specific contamination pattern and riverine influences were revealed. The results suggest that both direct and indirect sources contribute to the UV stabilizer and UV filter contamination in the study area.

欧洲北部和波罗的海沉积物中有机紫外线稳定剂和紫外线过滤剂的环境事件和危害

由于紫外线吸收化合物的大批量生产,其持久性或伪持久性及其潜在的不利影响,它们引起了人们的关注。这是第一项研究有机紫外线稳定剂和紫外线过滤剂在北海和波罗的海海表沉积物(包括相连的斯卡格拉克海峡和卡特加特海峡)中发生的环境和潜在危害的第一项研究。在整个研究区域中总共鉴定出19种物质,包括很少研究的化合物乙基己基三氮唑(EHT)和双辛唑(UV-360)。就检测频率(79%)和浓度(最高9.7 ng / g dw)而言,辛二烯(OC)是该研究中的主要化合物。在德国湾中,OC占紫外线稳定剂污染的65%以上。三嗪衍生物EHT在莱茵-默兹三角洲和德意志海岸线中的浓度最高为2.0 ng / g dw。在波罗的海,苯并三唑类紫外线稳定剂占污染的60%,其中主要成分为UV-360。估计的环境危害商表明,对北海和波罗的海底栖生物和沉积生物的影响可忽略不计。揭示了特定地区的污染模式和河流影响。结果表明,直接和间接来源均对研究区域的紫外线稳定剂和紫外线过滤剂造成污染。估计的环境危害商表明,对北海和波罗的海底栖生物和沉积生物的影响可忽略不计。揭示了特定地区的污染模式和河流影响。结果表明,直接和间接来源均对研究区域的紫外线稳定剂和紫外线滤光片造成污染。估计的环境危害商表明,对北海和波罗的海底栖生物和沉积生物的影响可忽略不计。揭示了特定地区的污染模式和河流影响。结果表明,直接和间接来源均对研究区域的紫外线稳定剂和紫外线过滤剂造成污染。
