  2. In this paper, kandelia candel ( l. ) druce hypocotyls were cultivated in sand and treated with 15 % seawater for 60 days under laboratory conditions. the influence of increasing concentrations of napthalene and pyrene ( 0, 0. 1, 1 and 10mg / l ) on hypocotyl germination and growth, photosynthesis metabolism, water metabolism and membrane protection system were observed to inquire into the ecophysiological responses of mangrove k. candel to pahs phytotoxicity. moreover, the concentration and distribution of parent polycyclic aromatic hydrocarbons ( pah ' s ) in surface sediment, underground root and leaf residue of mangroves in jiulong river estuary ( fugong, north and south shores of haimen island, baijiao ), neighbouring xiamen western harbour ( dong islet ) and dongzui harbour ( fenglin ) were examined
