RTECS#: CAS# 7440-50-8: GL5325000; GL7440000; GL7590000 LD50/LC50: Not available.
Carcinogenicity: CAS# 7440-50-8: Not listed by ACGIH, IARC, NTP, or CA Prop 65.
Epidemiology: No data available. Teratogenicity: No data available. Reproductive Effects: No data available. Mutagenicity: Genotoxicity Effects. Several in vitro studies (Table 2-4) have examined genotoxic effects of copper in nonhuman systems. The results of the tests using prokaryotic organisms are equivocal. However, positive results have been observed in vitro (Table 2-4) and in vivo (Table 2-5) in mammalian systems. At low levels of copper (0.01-0.1 mM Cu as copper sulfate), DNA strand breaks were not observed in rat hepatocytes; however, strand breaks did occur at high concentrations (0.04 mM Cu as copper sulfate) (Sina et al. 1983). In vivo studies with Inbred Swiss mice showed that copper exposure resulted in chromosomal aberrations and micronuclei and sperm abnormalities (Bhunya and Pati 1987). Copper binds with the phosphate on nucleotides and nucleic acids of DNA. Its mutagenic potential may be the result of this binding (Sharma and Talukder 1987). Although there is no data on the mutagenicity of copper in humans, in vivo studies and mammalian system in vitro studies suggest that copper is a potential human mutagen. [ATSDR] Neurotoxicity: No data available. Other Studies: EndPoint: Primary Organ: Renal toxicity (Kidney) 7.3.1 Oral 126.96.36.199 Copper(II) sulfate The critical study is that of Hébert et al. (1993) which is described here. In comprehensive 90-day studies in both rats and mice (Hébert et al., 1993), in which copper(II) sulfate pentahydrate was administered in the feed at up to 8000 mg/kg in rats (up to 138 mg Cu/kg body weight per day) and up to 16 000 mg/kg in mice (up to around 1000 mg Cu/kg body weight per day), there were no overt signs of toxicity other than a dose-related reduction in growth (statistically significant in male and female rats from 67 and 138 mg Cu/kg body weight per day, respectively, and in male and female mice from 97 and 267 mg Cu/kg body weight per day). Microscopic examination of the tissues revealed hyperplasia and hyperkeratosis in the forestomach in both species (from 34 mg Cu/kg body weight per day in rats and from 187-267 mg Cu/kg body weight per day in mice), and liver and kidney effects in the rats only (from 67 mg Cu/kg body weight per day). In the rats, iron levels were reduced in the spleen, and haematological changes indicative of microcytic anaemia were observed at 34 mg Cu/kg body weight per day and higher. The NOEL was 17 mg Cu/kg body weight per day in rats, and 44 and 126 mg Cu/kg body weight per day in male and female mice, respectively. The liver and kidney effects observed in the rats in this study included inflammation of the liver and degeneration of the kidney tubule epithelium, and were similar to those found at higher doses (> 100 mg Cu/kg body weight per day) in more limited studies in rats (Haywood, 1980, 1985; Haywood & Loughran, 1985).
7.4 Long-term exposure chronic toxicity or carcinogenicity
The chronic toxicity/carcinogenicity of copper compounds has not been well characterized (see Table 11). Increased mortality and growth retardation or effects on the liver, kidneys or stomach have been observed in rats following long-term ingestion of 27-150 mg Cu/kg body weight per day as copper(II) sulfate, or 44-45 mg Cu/kg body weight per day as copper(II) acetate, in several limited studies. Long-term ingestion of copper(II) sulfate at 10 mg Cu/kg body weight per day induced marked hepatotoxicity in rabbits. An oral study in dogs did not show significant toxic effects at the highest dose of 8.4 mg Cu/kg per day, given as copper gluconate (Shanaman et al., 1972).
The available studies of the carcinogenicity of copper compounds in rats and mice have given no indication that copper salts are carcinogenic. However, the short duration or low level of exposure, the small group sizes employed, the limited extent of histopathological examination, or inadequate reporting limits the conclusions which can be drawn from such studies. The studies summarized in Table 11 are, therefore, inadequate to test the carcinogenic potential of copper compounds with any degree of certainty. In several studies, administration of copper compounds inhibited the development of tumours induced by known carcinogens (see Table 11). INTERNATIONAL PROGRAMME ON CHEMICAL SAFETY.

World Health Organization Geneva, 1998 [INCHEM] EndPoint: Primary Organ: Immunotoxicity In an inhalation study in mice, single or repeated 3 h exposures to copper(II) sulfate aerosol resulted in significant immunosuppressive effects, including reduced bactericidal activity of the alveolar macrophages to Klebsiella pneumoniae and reduced resistance to infection by Streptococcus zooepidemicus. These effects were evident after a single exposure at 0.28 mg Cu/m3 and above and after 5 or 10 daily exposures at 0.06-0.07 mg Cu/m3. A NOEL was not established in these studies (Drummond et al., 1986). INTERNATIONAL PROGRAMME ON CHEMICAL SAFETY. ENVIRONMENTAL HEALTH CRITERIA 200: COPPER.

Remark: Inhalation: Copper fumes cause irritation of the eyes, nose and throat, and a flu-like illness called "metal fume fever". Symptoms of metal fume fever include fever, muscle aches, nausea, chills, dry throat, cough and weakness. The symptoms disappear after 24 hours. Metal fume fever appears after exposure to about 0,1 mg/m3. Repeated or prolonged exposure to copper fumes may cause the skin and hair to change colour. Renal damage reported. Nasal perforation reported in some cases. Chronic health affects, such as respiratory symptoms, gastrointestinal disturbances, nervous dysfunctions, dermatological and haematological changes and hepatomegaly. 75-100 copper workers, who were heavily exposed to copper dust of high purity, were examined over a 4-year period. The main findings were: - in workers with Cu-S between 0,8-2,0 mg/l: increased alpha-2-globulins, redblood-cells and haemoglobin; - in workers with Cu-S above 2,0 mg/l: different nervous symptoms, enlarged livers, abdominal distension and dermatological manifestations. Chronic irritative bronchitis was also observed. Lung damage following chronic exposure to copper dusts and fumes in industry is not described. The higher incidence of respiratory cancer reported in copper smelters is due to arsenic contained in the ore. Source: Montanwerke Brixlegg Ges.m.b.H.
