Description
Summary:Mangroves is an ecosystem which plays an economical role in Gabon for its watercourses where are used for fishing and marine traffic or as little bin for garbage and waste water disposal. These bad practices destroy that fragile ecosystem, perturbing like this carbon sequestration and biodiversity protection. Hence, the impact of the anthropogenic pollution stress of fishing engine oils so called hydrocarbons pollution on the chemical, microstructure and natural durability of Avicennia. germinans (L.)L. from Ambowé mangrove of the Estuary region of Gabon was studied. The results were compared with samples from Oveng and Mamboumba, two unpolluted sites of Libreville. Dichloromethane and hexane soluble extractives content decreased significantly (p
