    The assessment of heavy metal accumulation by myxomycetes
    (KNUCA, 2015) Kryvomaz, Tetiana
    The assessment of heavy metal accumulation by myxomycetes (slime moulds) has been made. The importance of these organisms for environmental safety monitoring was specified. Ecological and physiological mechanisms of ability of myxomycetes to concentrate metals and other elements from their substrates were analyzed. For five common myxomycetes species with relatively big fruiting body were compared chemical elements concentrations. Fuligo septica (L.) Wigg. was proposed as perspective bioindicator for the detection of Zn on the grounds of the ability to accumulate this metal and by reason of this species have widespread distribution in terrestrial ecosystems. Prospects of using slime molds as objects for bioremediation of contaminated soils were considered.

    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.
