  cis-Pt(NH3)2Cl2] is an experimental carcinogen. Exposure to complex platinum salts has been shown to cause symptoms of intoxication such as wheezing, coughing, running of the nose, chest tightness, shortness of breath, and cyanosis. Furthermore, many people worhng with platinum salts are troubled with dermatitis. They may become sensitized after years of exposure. Symptoms of platinum allergy include rhinitis, conjun- ctivitis, asthma, urticaria, and contact dermatitis. Mainly the ionic platinum chloro compounds [e.g., (NHN4)2(PtCl6), (NH4)2(PtC4), H2(PtCl6)] are responsible for this sensitivity. The bromide and iodde compounds are less effective. These platinum compounds form a platinum- protein conjugate that is the true allergen. Tetrachloroplatinates are mutagens. This seems to be true only of complex platinum salts. It does not apply to the complex salts of the other precious metals. Platinum amine nitrates and perchlorates either detonate when heated or are impact- sensitive.
