摘要：To assessment the effects on the ecosystem of Sundarbans a Mangrove Forest (SMF) in Bangladesh after oil spillages on 9th December 2014 into the shela river of Sundarbans, mainly focus on to determine the water quality and some trace elements content of Sundari (Heritierafomes) fruit and the aerial roots (pneumatophores) of Sundari. The water quality parameters viz, alkalinity, dissolved oxygen, hardness, pH, EC, ORP, salinity, nitrite and chloride contents were determine by using pH meter, DO meter, electroconductivity meter, Salinitimeter during high tide time and downstream. The nitrite and chloride contents of water and the trace elements contents of sundari fruits and roots were analyzed in the laboratory by using atomic absorption spectrophotometer. After oil spillage the alkalinity, dissolved oxygen (DO), hardness, EC, ORP, nitrite and chloride contents of water during high tide time and downstream were slightly decrease but the salinity of water decrease remarkable. The Fe and Zn contents in Heritierafomes fruits and pneumatophores of Heritierafomes were increased significantly but the Cu, Cd, Pb and Ni contents were remain constant. After analyzing theresults, in this study, it is clearly indicated that the criteria needed for the good quality of water and the some micro-nutrient contents of Heritierafomes fruits and pneumatophores of Heritierafomesare remarkable change due to the oil spill into the shela river of Sundarban as compare to before oil spillage. This study also represent that the Fe and Zn contents of Sundari fruits and roots are significantly increasing due to the massive changing of water quality of Shela river of Sundarbans. Finally, this study would helpful to measure the threaten affect on aquatic animals, others wild animal and different tree spices of the mangrove forestas well as the ecosystem of Sudarban.
