Benzotriazole ultraviolet absorbers (BUVs) are a new class of persistent organic pollutants, which are widely used as light stabilizers in various industrial products with good ultraviolet absorbing ability and thermal stability, among which 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol (UV-328) has been listed in the Stockholm Convention. Currently, there are a large number of domestic and international studies on the exposure of BUVs in the environment and living organisms, and the concentration of BUVs in sediments and soils generally reaches hundreds of ng/g, and they are frequently detected in water bodies and fish. Humans have an exposure risk through dietary intake and respiratory tract intake, but there are few reports on the load of BUVs in human urine and blood, and it is noteworthy that the load of BUVs in human breast milk can reach up to thousands of ng/g. In view of the bioaccumulation and potential toxicity of BUVs, this paper provided a detailed overview of the exposure to BUVs in various types of environmental, biological, and human tissue samples. This paper briefly summarized the potential hazards of BUVs, such as liver and kidney target organ toxicity, endocrine disrupting effects, and immunotoxicity and neurotoxicity, aiming to provide a reference for the assessment of the health risk of BUVs in human beings.
