英文摘要	National Natural Science Foundation of China [20977045, 21107046]; State Key Laboratory of Marine Environmental Science, Xiamen University; Fundamental Research Funds for the Central Universities; Shanghai Tongji Gao Tingyao Environmental Science & Techno; Our experiments revealed that a model sunscreen agent, p-aminobenzoic acid (PABA), can be effectively transformed through reactions that are mediated by simulated solar irradiation. We systematically explored the effects of nitrate ions, bicarbonate and different types of natural organic matter (NOM) on the degradation of PABA by simulated solar irradiation. Experimental data suggest that these components ubiquitous in nature water have different influence on the rates of the photoinduced removal of PABA. Products were extracted and analyzed using LC/MS and a total of four products probably resulting from center dot OH and center dot NO(2) radicals attack were identified and the possible reaction pathways were proposed. The findings in this study provide useful information for understanding the environmental transformation of sunscreen agent in aquatic system. (C) 2011 Elsevier B.V. All rights reserved.
