Scientific basi of assessment of phytotoxicity Metals (Cd, Pb, Co, Cu, Ni, Zn)
Journal Title: Екологічні науки - Year 2018, Vol 21, Issue
Abstract
The study’s results of the features of the metals (Cd, Pb, Ni, Co, Cu, Zn) influence on phytocomponent in ecosystems are presented in the thesis. The methodology for assessing the risk of metals in the ecosystem through the development of a Phytoletal Dose (PhLD50) algorithm was expanded, which is the universal reliable index of phytotoxicity of metals and allows comparative evaluation of the toxicity of these pollutants. A scientific approach to ecological standardization has been developed, which is the basis for regulating the safe level of metals in the soil concerning the phytocomponent in the ecosystem by means of Phyto maximum allowable concentration. It has been established that the polarity of metal compounds allows predicting their hazard, in particular, phytotoxicity. The phytotoxicological classification of the hazardous metals has been developed, which allows detecting their harmful effects on the phytocomponent in the polluted ecosystem.
