英文摘要	National Natural Science Foundation of China [21177102, 21075102, 21207103]; Public Benefit Project of Zhejiang Province [2012C31025]; Natural Science Foundation of Zhejiang Province [LY13H180012]; Scientific Research Fund of Zhejiang Provincial Education Department [Y201222932]; Project of Wenzhou Municipal Science and Technology [G20110004]; Science and Technology Innovation Action of College Student of Zhejiang Province [2013R413010]; An established synchronous solid surface fluorimetry (S-SSF) was utilized for in situ study the photolysis processes of anthracene (An) and pyrene (Py) adsorbed on the leaf surfaces of Kandelia obovata seedlings (Ko) and Aegiceras corniculata (L.) Blanco seedlings (Ac). Experimental results demonstrated that the photolysis of An and Py adsorbed on the leaf surfaces of two mangrove species under the laboratory conditions, followed first-order kinetics with their photolysis rates in the order of Ac. Ko. In addition, with the same amount of substances, the photolysis rate of An adsorbed on the same mangrove leaf surfaces was much faster than the adsorbed Py. In order to investigate further, the photolysis processes of An and Py in water were also studied for comparison. And the photolysis of An and Py in water also followed first-order kinetics. Moreover, for the same initial amount, the photolysis rate of the PAH in water was faster than that adsorbed on the leaf surfaces of two mangrove species. Therefore, photochemical behaviors of PAHs were dependent not only on their molecular structures but also the physical-chemical properties of the substrates on which they are adsorbed.
