Abstract：
There is increasing evidence that sunscreen, more specifically the organic ultra-violet filters (O-UVFs), are toxic for aquatic organisms. In the present study, we simulated an environmental sunscreen exposure on the teleost fish, Chelon auratus. The first objective was to assess their spatial avoidance of environmental concentrations of sunscreen products (i.e. a few μg.L-1 of O-UVFs). Our results showed that the fish did not avoid the contaminated area. Therefore, the second objective was to evaluate the toxicological impacts of such pollutants after 35 days exposure to concentrations of a few μg.L-1 of O-UVFs. At the individual level, O-UVFs increased the hepatosomatic index which could suggest pathological alterations of the liver or the initiation of the detoxification processes. At the cellular level, a significant increase of malondialdehyde was measured in the muscle of fish exposed to O-UVFs which suggests a failure of antioxidant defences and/or an excess of reactive oxygen species.
摘要：
越来越多的证据表明防晒霜,更具体地说，有机紫外线滤光片(O-UVFs)，对水生生物有毒。在本研究中,我们模拟了硬骨鱼的环境防晒暴露，Chelonauratus.第一个目标是评估其空间避免防晒产品的环境浓度（即几μg。L-1的O-UVFs)。我们的结果表明，鱼没有避开污染区域。因此,第二个目标是评估这些污染物暴露于浓度为几μg的35天后的毒理学影响。L-1的O-UVFs。在个人层面,O-UVF增加了肝细胞指数，这可能表明肝脏的病理改变或解毒过程的开始。在细胞层面,在暴露于O-UVFs的鱼的肌肉中，丙二醛显着增加，这表明抗氧化剂防御失败和/或活性氧过多。
