SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Anaemia results from the excessive absorption of zinc suppressing copper and iron absorption, most likely through competitive binding of intestinal mucosal cells. Unbalanced levels of copper and zinc binding to Cu,Zn-superoxide dismutase has been linked to amyotrophic lateral sclerosis (ALS). Stomach acid dissolves metallic zinc to give corrosive zinc chloride, which can cause damage to the stomach lining. Metal fume fever is thought to be an immune response to inhaled zinc.

Ingestion of large doses of zinc causes stomach cramps, nausea, and vomiting. Acute inhalation of large amounts of zinc causes metal fume fever, which is characterized by chills, fever, headache, weakness, dryness of the nose and throat, chest pain, and coughing. Dermal contact with zinc results in skin irritation. (L49)

In preemployment and periodic physical examinations, special attention should be given to the skin and to the history of allergic dermatitis, as well as to exposed mucous membranes, the eyes, and the respiratory system. ... Smoking history should be known. Measurement of urinary zinc excretion may be useful.

The assessment of zinc exposure can be accomplished through measurement of zinc. The presence of excess zinc ... can indicate high exposure to zinc; however, no information was found in the literature regarding the accuracy of these levels in predicting possible health effects. Blood Reference Ranges: Normal - average level 1200 ug/dl; Exposed - not established; Toxic - not established. Serum or Plasma Reference Ranges: Normal - average levels 100 ug/dl; Exposed - not established; Toxic - not established. Urine Reference Ranges: Normal - average levels 0.5 mg/g creatinine or 150 to 1200 ug/24 hours; Exposed - urinary concentrations of 600 to 700 ug/l were found in workers exposed to zinc oxide at levels of 3 to 5 mg/cu m; Toxic - greater than 1200 ug/24 hours has been indicated as a toxic urinary level of zinc; however no information was located relating to the severity of symptoms seen with high urinary zinc levels. /Zinc/

Respiratory Symptom Questionnaires: Questionnaires have been published by the American Thoracic Society and the British Medical Research Council. These questionnaires have been found to be useful in identification of people with chronic bronchitis, however certain pulmonary function tests such as FEV1 have been found to be better predictors of chronic airflow obstruction. /Zinc/

Chest Radiography: This test is widely used for assessing pulmonary disease. Chest radiographs have been found to be useful for detection of early lung cancer in asymptomatic people, especially for detection of peripheral tumors such as adenocarcinomas. However, even though OSHA mandates this test for exposure to some toxicants such as asbestos, there are conflicting views on its efficacy in detection of pulmonary disease. /Zinc/

The ability of zinc chloride to induce morphological transformation in Balb/3T3 mouse cells (Cell transformation Assay) was evaluated in the presence of added metabolic activation by Aroclor-induced rat liver S-9 fraction. Based on preliminary clonal toxicity determinations (exposure time = 2hrs), zinc chloride, diluted with phosphate buffered saline, was tested at 200, 400, 600 or 800ug/ml in the presence of metabolic activation, with cell survival ranging from 83% to 1% relative to the solvent control. Treatments at 600 and 800ug/ml were too toxic and the cells failed to grow. Treatments at 200 and 400ug/ml produced significantly greater transformation frequencies (p < 0.05 and p < 0.01, respectively, Modified Poisson Distribution) relative to the solvent control.

The frequency of forward mutations was determined at the thymidine kinase (TK) locus of the mouse lymphoma L5178Y cell line exposed in vitro to zinc chloride in the presence of metabolic activation provided by Aroclor-induced rat liver S9 fraction. Mutagenic effects were observed in cultures after exposure to test article at concentrations ranging from 4.2 to 56 ug/plate, as indicated by 2 to 19.2 fold increases in mean mutant frequency compared to controls. The percent growth ranged from 95% to 10%, while in preliminary cytotoxicity assay, all cells were killed at 50 ug/ml.

The Agency has sufficient information on the human health effects of zinc salts and on it potential for causing effects in fish and wildlife and the environment when used to control moss and fungus growth in outdoor residential areas, on structures, in pressure-treated lumber and incorporated into fibers used in carpet. The Agency concludes that products containing zinc salts for these uses are eligible for reregistration. Only certain generic physical chemistry data studies on zinc salts still are needed as comfirmatory information. The Agency has determined that zinc salt containing products, labeled and used as specified in this Reregistration Eligibility Document will not pose unreasonable risks or adverse effects to humans or the environment.

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Zinc chloride is found on List D. Case No: 4099; Pesticide type: fungicide, herbicide, antimicrobial; Case Status: RED Approved 09/92; OPP has made a decision that some/all uses of the pesticide are eligible for reregistration, as reflected in a Reregistration Eligibility Decision (RED) document.; Active ingredient (AI): Zinc chloride; Data Call-in (DCI) Date(s): 10/07/92; AI Status: OPP has completed a Reregistration Eligibility Decision (RED) document for the case/AI.
