title: Industrial toxicology of metals of the platinum group.
abstract: Metals of the platinum group have found important application in technology and industry. Compounds of these metals display a broad spectrum of toxic effects on the organism. In persons dealing with them in the production, they induce allergic occupational diseases of the respiratory passages, dermatoses, affections of the eyes. Their resorptive chronic effect in experiment is characterized by reduction in the body mass of the animals and the content of haemoglobin in the blood, by disturbances of the protein-synthesizing function of the liver, decreased cholinesterase activity in the blood, impaired carbohydrate and lipid metabolism, reduced concentrating capacity of the liver, development of glomerulonephritis. Platinum and platinoids irritate mucous membranes and skin. They penetrate the organism through intact skin. Data on the distribution of the metals in the organs and on their elimination from the organism are reported. Toxicity of the metals of the platinum group is correlated with valence of the compounds and with electron structure. MAC for milling and condensation aerosols of poorly soluble compounds (metal and its oxides) are recommended at 0.1 mg/m3. For aerosols of all soluble compounds of platinum and platinoids, MAC of 0.001 mg/m3 are recommended.
