Assessment environmental safety for mangrove biome
(КНУБА, 2016) Kryvomaz, Tetiana
Mangrove ecosystem was analyzed from ecological safety point of view. The comparison anthropogenic impact on some mangrove biome in Brazil and Seychelles show that mangrove in Brazil affected by industrial and anthropogenic loading, whereas on Seychelles recreational disturbance and pollution are biggest problems for mangrove. Threats to mangrove ecosystem include: clearing, overharvesting, water reduce, overfishing, coral reefs destruction, pollution, climate change. Analyses of mangrove soil find big transformation ratio soil elements to mobile forms for Fe (Ks-mf =253,81) and Cu (105,45), which is make this metal accessible for other living organisms and return to nutrient cycle. Mangrove systems support a range of species and provide a number of essentials for many different living organisms. The ability myxomycetes Hemitrichia serpula accumulate Ca (Ka = 443,69) and Zn (247,41) from environ-ment was discover; Ni (60), Mn (16,04) and Pb (11,94) also show high level elements concentra-tion in compere with their content in soil. Mangroves provide a wide range of goods and ecosys-tem services with great economic and environmental consequences. Risk for mangrove assess by exceeding the rate of the disappearance and reduces the capacity to function effectively as a viable ecosystem.
