Information was reported under section 71 of CEPA for 22 cobalt-containing substances that were manufactured, imported or used above reporting thresholds in Canada in recent years (2006–2011). Four substances were reported to be in commerce in quantities greater than 1 000 tonnes, while the others were in commerce in quantities ranging from tens to hundreds of tonnes. Activities and uses reported for substances having the highest quantities in commerce included as an intermediate in metallurgical processes, in non-ferrous metal smelting and refining, as a component in alloys and carbides, and in feed supplements and fertilizers, hard material tools, paints and coatings, plastics, rubber, and batteries.

There are natural and anthropogenic sources of cobalt to the environment. Anthropogenic sources involve cobalt production (e.g. mining); the manufacture, import and use of cobalt-containing substances, products and manufactured items; as well as the incidental release of cobalt as a result of activities such as fossil fuel combustion, mining activities and waste management. This assessment considers combined exposure to the cobalt moiety, from natural or anthropogenic sources, whether it is present in environmental media (e.g. water, sediment, soil, air), food or products. The assessment focuses on the cobalt moiety, and thereby considers cobalt in its elemental form, cobalt-containing substances and cobalt released in dissolved, solid or particulate form. Therefore, substances considered in this assessment are not limited to those having met the categorization criteria. All substances that have the potential to dissolve, dissociate and/or degrade to release cobalt through various transformation pathways can potentially contribute to the exposure of living organisms to bioavailable forms of cobalt.

Following releases to the environment, cobalt may enter the water, soil and air media. The water solubility of cobalt and cobalt-containing substances ranges widely, from sparingly soluble to greater than 106 mg/L. Therefore, to various extents, these substances will dissolve in contact with moisture in the aquatic and soil media and will yield a variety of dissolved cobalt species of varying proportions depending on the environmental conditions. Dissolved cobalt, as the bioavailable fraction, may be taken up by aquatic, soil- and sediment-dwelling organisms and has been demonstrated to cause harm to these organisms at very low concentrations. Survival, growth, or reproduction of these organisms may be affected. The bioaccumulation potential of cobalt is relatively low, yet cobalt uptake may still lead to levels causing harm to sensitive species at body concentrations higher than required for essentiality.

Ecological exposure scenarios were developed for the various activities that may represent significant sources of release of cobalt or cobalt-containing substances to the environment. Exposure to cobalt was assessed based on modelled (predicted) or measured concentrations of total or dissolved cobalt in environmental media. Substance-specific exposure scenarios were developed to represent releases associated with the following sectors mainly involving manufacture: rubber, chemicals, paints and coatings, plastics (polyester resin), fertilizers, animal feed, alloys/superalloys, and base metals smelting and refining. In addition, exposure was assessed for the following sectors based on their potential to release cobalt incidentally (as a by-product): metal mining, base metals smelting and refining, iron and steel, electricity (power generation), petroleum refining, oil sands, pulp and paper mills, electrical and electronic equipment, disposal and waste management.

Risk quotient analyses were performed comparing exposure concentrations to effects concentrations of dissolved or total cobalt. As a result, a likelihood of harm to aquatic, soil- or sediment-dwelling organisms is identified mainly in the vicinity of some facilities for a number of sectors. The metal mining and base metals smelting and refining sectors are of concern for cobalt. Releases of liquid effluent were found to be the most important source of exposure for aquatic organisms near these activities. Drainage from historical mining activities and, to a lesser extent, metal mining exploration were also found to be a cause for concern for cobalt. Other sectors or sources found to be of concern were pulp and paper mills and leachate from landfills.

Considering all available lines of evidence presented in this screening assessment, there is a risk of harm to organisms, but not to the broader integrity of the environment, from cobalt and soluble cobalt compounds. It is concluded that cobalt and soluble cobalt compounds meet the criteria under paragraph 64(a) of CEPA, as they are entering or may enter the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity. However, it is concluded that cobalt and soluble cobalt compounds do not meet the criteria under paragraph 64(b) of CEPA, as they are not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger to the environment on which life depends.

For the human health assessment, general population exposure was characterized using nationally representative biomonitoring data collected from 2009 to 2011 as part of the Canadian Health Measures Survey (CHMS). Whole blood cobalt concentrations are representative of daily exposure to natural and anthropogenic sources of bioavailable cobalt from all sources, including environmental media, food and the use of products. The results of the CHMS did not show statistically significant differences in blood concentrations of cobalt between the general population and subpopulations based on age or gender. Inhalation exposure to solid or particulate forms of the cobalt moiety was evaluated using concentrations of cobalt measured in personal air samplers and is considered most representative of typical daily exposures.

Based on the weight-of-evidence analysis, international agencies have classified cobalt-containing substances as carcinogens. These classifications are primarily based on the evidence from site-specific tumours observed in the respiratory tract of rodents exposed to cobalt sulphate via the inhalation route. Available short-term and subchronic oral studies in animals, or epidemiology studies in humans, do not provide evidence for potential systemic or site-specific carcinogenicity by the oral route. Genotoxicity of cobalt is likely mediated by indirect mechanisms, including generation of reactive oxygen species and inhibition of DNA repair enzymes. Lethal cardiomyopathy in malnourished individuals who consumed large quantities of beer containing cobalt sulphate was identified as a critical effect for risk characterization. Selection of this endpoint is considered conservative, as the affected population may have been more susceptible than the general population due to dietary insufficiencies and prior cardiac damage from excessive alcohol consumption. Polycythemia (the increase of red blood cells and haemoglobin) observed in humans was identified as another critical health effect for the risk characterization of the general population. The critical effect identified for inhalation exposure was reduced lung function reported in individuals occupationally exposed to dust containing cobalt in the diamond polishing industry.

These endpoints were considered conservative and protective of potential harmful effects observed in the animal database, including developmental, reproductive and carcinogenic effects. The margins of exposure between cobalt levels in whole blood of Canadians from a nationally representative survey or cobalt levels in personal air samples and conservative effect levels are considered adequate to address uncertainties in the health effects and exposure databases.

Therefore, it is concluded that cobalt and cobalt from cobalt-containing substances, including the substances identified in the table above, do not meet the criteria under paragraph 64(c) of CEPA, as they are not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.


It is concluded that cobalt and soluble cobalt compounds meet one or more of the criteria set out in section 64 of CEPA. In addition, cobalt and soluble cobalt compounds have been determined to meet the persistence criteria, but do not meet the bioaccumulation criteria as set out in the Persistence and Bioaccumulation Regulations of CEPA.

The final screening assessment and the proposed risk management approach document for these substances are available on the (Chemical Substances) website (
