| hazards summary | Other than the skin and respiratory irritant effects of zirconium chloride, work-related diseases caused by zirconium have not been documented. Zirconium compounds, both soluble and insoluble, have the following notation, Danger of sensitization of the airways and the skin. Repeated inhalation of zirconium tetrachloride mist by dogs for 2 months at 6 mg/m3 as zirconium caused slight decreases in hemoglobin and in erythrocyte counts, with some increases in mortality over that of controls. these effects may have been due to the liberation of hydrogen chloride. Generally considered to be of low toxicity. Zirconium chloride (ZrCl4) can cause acute pneumonitis. No lung changes were found in 32 workers with 1-17 years of exposure to zirconium metal reactor parts. A lens grinder who mixed zirconium oxide powder and polished optical lenses developed interstitial fibrosis after a latency of 15 years. Soluble zirconium compounds include nitrates, acetates, sulfates, chlorides, bromides, iodides, and salts of Na, K, and ammonium. Insoluble zirconium compounds include hydroxides, carbonates, and phosphates. |
