Abstract: Based on the monitoring of oil pollution near the ship-disassembling workshop of XiamenSpecial Economic Zone,the method of biomonitoring coastal oil pollution by means of mang-rove plant(Avicennia marina)is studied.The results show that oil contaminant on leafsurface has a monitoring and“recording”function to oil pollution in nearby coasts.Accor-ding to the water sample analysis,oil contaminant on leaf surface increases with increasingoil pollution.Mangrove plant growing on tidal zone has an oil-resistivity.It can be usedfor monitoring coastal oil pollution.
