Platinum is widely used as a catalyst in different chemical synthesis, industrial processes, and as an active part of car catalytic converters. Platinum complexes, mainly cis-platin and carboplatin, are used as active anti-tumour agents in medicine. The toxic effect of platinum and its compounds and their influence on the occupationally exposed persons as well as different sources of platinum emission to the environment are discussed in this paper. A continuous increase of platinum concentration in the environment could be observed over the last years. The elevated level of platinum was found in soil, grass, sewage sludge, road dust. Due to the fact that the main part (about 75%) of the anti-cancer drugs is excreted from the body several days or weeks after usage, the effluents from hospitals also contain significant platinum concentration. Platinum of this origin could enter the human food chain by inhalation and digestion truck. The information on the mobility, bioavailability and speciation of platinum in the environment is needed for better understanding of its environment impact and the influence on human health. The present knowledge on these problems are summarised in this review.
