Zinc and its compounds

In addition to the conventional pollutant constituents, USEPA made a survey of the presence of the 126 toxic pollutants listed as priority pollutants in refinery operations in 1977 [5]. The survey responses indicated that 71 toxic pollutants were purchased as raw or intermediate materials 19 of these were purchased by single refineries. At least 10% of aU refineries purchase the following toxic pollutants benzene, carbon tetrachloride, 1,1,1-trichloroethane, phenol, toluene, zinc and its compounds, chromium and its compounds, copper and its compounds, and lead and its compounds. Zinc and chromium are purchased by 28% of all refineries, and lead is purchased by nearly 48% of all plants. [Pg.256]

Swedish law requires that major retailers make an assessment of potential health and environmental hazards when deciding on which products to stock and sell. As a guide to which chemicals should be avoided, KEMI has published a list of especially hazardous chemicals ( OBS-listan ). The hazard profiles of the KEMI-listed substances differ widely, from decidedly toxic compounds, like arsenic salts and benzene, to practically innocuous substances, such as metallic zinc and many zinc compounds. (Like any other chemical, including table salt, zinc and its compounds should, of course, not be dumped in rivers in large quantities, but they are perfectly safe in most other contexts.)... [Pg.256]

Toxicity Zinc and its compounds are relatively nontoxic, but very large doses can produce acute gastroenteritis characterized by nausea, vomiting, and diarrhea. The recommended dietary allowance (RDA) for zinc is 15 mg/day for men, 12 mg/day for women, 10 mg/day for children, and 5 mg/day for infants. Not enough zinc in the diet can result in a loss of appetite, a decreased sense of taste and smell, skin sores and slow wound healing, or a damaged immune system. [Pg.79]

I ARC Cancer Review Group 1 IMEMDT 58,41,93 Human Sufficient Evidence IMEMDT 58,41,93 Animal Sufficient Evidence IMEMDT 1,17,72 Animal Sufficient Evidence IMEMDT 23,143,80 Animal Sufficient Evidence IMEMDT 58,41,93. Beryllium and its compounds, as well as zinc and its compounds, are on the Community Right-To-Know List. [Pg.169]

CONSENSUS REPORTS Reported in EPA TSCA Inventory. Zinc and its compounds are on the Community Right-To-Know List. SAFETY PROFILE Poison by intraperitoneal route. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits very toxic fumes of NOx, ZnO, and SOx. See also ZINC COMPOUNDS and CARBAMATES. [Pg.186]

CONSENSUS REPORTS Manganese and its compounds, as weU as zinc and its compounds, are on the Community Right-To-Know List. [Pg.621]

Just as zinc deficiency has been associated with adverse effects in humans and animals, overexposures to zinc also have been associated with toxic effects. This chapter contains a description of the toxic effects that have been associated with exposures to high levels of zinc and selected zinc compounds by the inhalation, oral, and dermal routes. Specifically, zinc chloride, zinc oxide, zinc sulfate, and zinc sulfide will be considered. Other zinc compounds are discussed in this chapter whenever data regarding these compounds add relevant information to the discussion on zinc. Any general comments regarding the lack of data on zinc refer to both zinc and its compounds. [Pg.18]

Respiratory Effects. Respiratory disorders have been observed in humans and animals after acute inhalation exposure to zinc and its compounds. No adverse respiratory effects have been observed following ingestion or dermal application of zinc or its compounds. [Pg.71]

Zinc and its compounds induce testicular sarcomas in birds and rodents when injected directly into the testes however, zinc is not carcinogenic by any other route. Growth of animal tumors is stimulated by zinc, and retarded by zinc deficiency. Under some conditions excess zinc can suppress carcinoma growth, although the mechanisms are imperfectly understood. Organozinc compounds are effective mutagens when presented to susceptible cell populations in an appropriate form the... [Pg.887]
