PLАТINUM-GRОUР ELEMENTS IN THE ENVIRONMENT AND THEIR ECOLOGICAL HAZARDS
Abstract
The paper offers an analysis of the published
data on the volumes of anthropogenic emissions of platinum-
group elements (PGEs) in the environment, on species
of PGEs in the emissions and on their availability to living
organisms. Short- and long-term effects of PGEs on living organisms
are considered. The mechanisms of the toxic effect
of PGEs on living organisms and their ability to interact with
DNA, amino acids, proteins and other biological compounds
are discussed. It is shown that the ability of the PGEs to accumulate
in the environment, in combination with a high toxicity
of some compounds of these elements, determines their
environmental hazards.
