Transformation products (TPs) of micropollutants contaminating our water resources have become an emerging issue due to the potential threats they pose to environmental and human health. This study investigated the transformation chem., toxicity, physicochem. properties and environmental behavior resulting from photocatalytic transformation of organic UV filters as model micropollutants. 3-Benzylidene camphor (3-BC), 4-hydroxybenzophenone (4-HB) and octocrylene (OC) were effectively degraded by UV-A/TiO2 treatment, with TPs identified and characterized with high resolution mass spectrometry. Nitrated-TPs were observed to be formed in the presence of nitrite and nitrate for 3-BC and 4-HB, suggesting that the transformation process could be altered by components in the water matrix. Vibrio fischeri bioluminescence inhibition assay revealed an increase in toxicity of TPs derived from photocatalytic treatment, with quant. structure-activity relationship model (ECOSAR) predicted an enhanced toxicity of individual TPs′ after transformation. Assessment of physicochem. properties and environmental behavior suggested that TPs as compared to parent organic UV filters, may represent even greater hazards due to their increased water solubility, persistence and mobility – in addition to retaining the parent organic UV filter′s toxicity. The results provide important information relevant to the potential risks for the selected organic UV filters, and their corresponding transformation products. The experimental process involved the reaction of 2-Ethylhexyl 2-cyano-3,3-diphenylacrylate(cas: 6197-30-4).Reference of 2-Ethylhexyl 2-cyano-3,3-diphenylacrylate
