Assessment of mangrove environmental safety by analyzes of metals transition
(2016) Kryvomaz, Tetyana; Andrusishina, Iryna
The study of metals transition in mangrove biome by analyzes of element concentration in plant, myxomycetes and soil for preliminary assessment of environmental safety. Methodology. Samples of soil, leaves litter, steam of living palm and myxomycetes fruiting body from Seychelles mangrove biome on Praslin island were analyzed by method of inductively coupled plasma atomic emission spectroscopy. Results. The scheme of 11 elements (Al, Ca, Cd, Cu, Fe, Mg, Mn, Ni, Pb, Si, Zn) accumulation demonstrates that heavy metals concentration increases in the direction from substrates to myxomycetes, and it decline from the forest floor to the trees. The ability myxomycetes Hemitrichia serpula accumulate Ca (Km-s = 443,69) and Zn (247,41) from environment was discover; Ni (60), Mn (16,04) and Pb (11,94) also show high level elements concentration in compere with their content in soil. The research finds big transformation ratio soil elements to mobile forms of soil for Fe (253,81) and Cu (105,45). Originality. For the first time the elements concentration in plant, myxomycetes and soil in mangrove were analyzed from ecological safety point of view. Practical value. Myxomycetes have undiscovered potential for bioindications and bioremediation of heavy metal and environmental management. References 10, no tables, figures 5.
