Zinc carbonate appears as a white crystalline solid or powder that is insoluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Used in pharmaceuticals, to make other zinc compounds, as a feed additive.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Trace minerals added to animal feeds as nutritional dietary supplements are generally recognized as safe when added at levels consistent with good feeding practice. Zinc carbonate is included on this list.

|Warning|H400 (85.33%): Very toxic to aquatic life [Warning Hazardous to the aquatic environment, acute hazard]|P273, P391, and P501|Aggregated GHS information provided by 262 companies from 13 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.

Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 1000 lb or 454 kg. The toll free number of the NRC is (800) 424-8802; In the Washington D.C. metropolitan area (202) 426-2675. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

The effects of Eimeria acervulina infection (duodenal coccidiosis) on cadmium toxicity and zinc status in the young chick /were evaluated/. Additions of cadmium (45 mg/kg) were made to diets that contained either 0 or 52 mg/kg supplemental zinc (from zinc carbonate). Growth and efficiency of feed utilization were reduced by dietary cadmium addition while concurrent coccidial infection reduced these parameters further. Addition of cadmium also increased cadmium content of liver and kidney and depressed hemoglobin, hematocrit, and plasma zinc content. Coccidial infection exacerbated tissue cadmium deposition and depressed hematological parameters further. Although dietary zinc addition ameliorated some of the adverse effects of cadmium toxicity, cadium administration tended to enhance tissue zinc deposition.

The effects of different amounts of dietary zinc on the zinc absorption rate and on zinc, calcium and magnesium concn in tissues of MOPC104E tumor bearing Balb/c female mice were determined. Three groups of 7 mice each (each mouse inoculated with approx 1.25 million MOPC104E cells) were given one of three experimental diets containing adequate amounts of zinc (40 ug zinc/g), a zinc deficient diet (1.0 ug zinc/g), or a zinc excess diet (1 mg zinc/g). A group of 7 nontumor bearing mice was fed laboratory mice chow as a control. The zinc deficient diet contained 37.5 ug zinc/g. For the zinc adequate diet, 71.0 mg zinc carbonate/kg diet was added to the zinc deficient diet. For the zinc excess diet 1917.9 mg zinc carbonate/kg diet was added. After 14 days on the special diets, mice were given an intragastric dose of a 200 ul solution containing 0.37 MBq (65)zinc (specific activity: 37 MBq/mg). (65)Zn was determined in various organs by gamma counting. Another set of 28 mice were placed in the same experimental conditions as described above. After anesthesia with nembutal injection, each organ was analyzed for concn of zinc, calcium, and magnesium by atomic absorption spectrophotometry. The zinc absorption rate was inversely related to the amounts of zinc in the diet and was lower than that of nontumor bearing control mice fed a laboratory mice chow. Zinc concn of tumor bearing mice were also low compared with control mice but tumor zinc concn, regardless of the concn of zinc in the diets, were higher than those of normal tissues of the host other than the pancreas.
