The presence of ultraviolet filters (UVFs) and stabilizers (UVSs) was evaluated for the first time in the common bottlenose dolphin (Tursiops truncatus). UVFs and UVSs are compounds of growing concern because their effects on the environment are not completely known. UVFs and UVSs are added to personal care products (PCPs), such as cosmetics and products related to sun care and once released to the aquatic ecosystem, marine organisms can bioaccumulate these substances. This work aimed to determine the presence of 12 UVFs and UVSs in cetacean blubber samples to assess the pollution to which these animals of the highest trophic chain levels are exposed due to human activity. Analytical determinations were carried out using a method based on microwave-assisted extraction combined with ultrahigh-performance liquid chromatography and tandem mass spectrometry detection. The developed method was successfully applied to determine the target compounds in the blubber tissues of five necropsied common bottlenose dolphins. Three of the 12 studied compounds, namely 2-ethylhexyl 2-cyano-3,3-diphenylprop-2-enoate (octocrilene, OC), 2-hydroxy-4-methoxybenzophenone (benzophenone 3, BP3) and 3-methylbutyl (E)-3-(4methoxyphenyl) prop-2-enoate (IMC), were detected in several samples. Of the identified compounds, OC was present in all the samples and at the highest concentration within the range from 52.61 ± 18.59 to 108.0 ± 11.32 ng·g.
首次对宽吻海豚（瓶鼻海豚）体内的紫外线过滤剂（UVFs）和稳定剂（UVSs）进行了评估。UVFs和UVSs是日益受到关注的化合物，因为它们对环境的影响尚未完全明确。UVFs和UVSs被添加到个人护理产品（PCPs）中，如化妆品和防晒相关产品，一旦释放到水生生态系统中，海洋生物就会生物累积这些物质。这项工作旨在确定鲸类动物脂肪样本中12种UVFs和UVSs的存在情况，以评估处于最高营养级的这些动物因人类活动而受到的污染程度。采用基于微波辅助萃取结合超高效液相色谱和串联质谱检测的方法进行分析测定。所开发的方法成功应用于测定5只经尸检的宽吻海豚脂肪组织中的目标化合物。在所研究的12种化合物中，有3种在多个样本中被检测到，即2-乙基己基2-氰基-3,3-二苯基丙烯酸酯（桂皮酸盐，OC）、2-羟基-4-甲氧基二苯甲酮（二苯甲酮3，BP3）和3-甲基丁基（E）-3-（4-甲氧基苯基）丙烯酸酯（IMC）。在已鉴定的化合物中，OC存在于所有样本中，且浓度最高，范围为52.61±18.59至108.0±11.32 ng·g。
