Mercury is a naturally occurring element that is also present in the environment as a result of human activities. Water bodies can be contaminated with mercury from industrial sources, such as pulp and paper mills, and from the soil when large reservoirs are created by hydro-electric dams. Methyl mercury is considered the most toxic form of mercury to human health and is formed when bacteria interact with mercury present in water and plants. Methyl mercury accumulates up the food chain, and predatory fish generally represent the main source of exposure from the diet.
Radionuclides are elements that release energy called radiation. Radionuclides originate from both natural (e.g. soil and rock) and artificial (e.g. certain industrial, military and medical applications) sources (https://www.canada.ca/en/health-canada/services/health-risks-safety/radiation/types-sources/environmental.html).

Polychlorinated biphenyls (PCBs) are a class of industrial chemicals that were used in a wide variety of applications including transformer oils, paints, and lubricants. PCBs are lipophilic compounds and accumulate in the tissues of biological organisms and bioconcentrate through the food chain. These compounds are thermally stable, persist in the environment and are subject to long-range transport. Canadian regulations related to PCBs came into force in 2008, which limit the release of these chemicals to the environment.
Di-(2-ethylhexyl) adipate (DEHA) is widely used as a plasticizer in food contact materials, such as PVC food wrapping or cling films used to rewrap meat poultry, fish, cheese, and other foods. DEHA can also be found in PVC gaskets of lids for glass jars. Like other plasticizers, DEHA is not chemically bound to the polymer and has been found at very low levels in foods due to migration from the cling films. Repeated oral exposure to DEHA may be associated with liver, kidney, reproductive, and developmental effects.
A national community-based program launched in 1993, funded by the Public Health Agency of Canada.
Metals are naturally-occurring elements that may be present in very low amounts in rock, water, soil, or air. Finding these substances in food products is not unexpected as trace levels generally reflect normal accumulation from the environment. They may be present in finished foods due to their presence in the ingredients used to manufacture those foods, and/or may be unintentionally incorporated along the food production chain. Metals of highest concern to human health include arsenic, cadmium, lead, and mercury and these have been shown to have effects on human health following long term exposure.
Bisphenol A (BPA) is a chemical used in the production of polycarbonate (PC) and epoxy resins. PC is used in food storage containers such as water bottles, and epoxy resins are used in the internal coating for food and beverage cans to protect the food from direct contact with metal. Under certain conditions, small amounts of BPA can migrate from PC plastic containers and cans with epoxy coating into foods, especially at elevated temperatures. BPA is an endocrine disruptor, and mimics the action of the hormone estrogen, although its potency is orders of magnitude lower than endogenous estrogens.
Ochratoxin A (OTA) is a natural toxin produced by fungal species in the genera Aspergillus and Penicillium. This naturally occurring toxin can be found in a broad group of agricultural products such as cereal grains, coffee, and fruits. Higher levels of OTA can result from the improper storage of grains in moist conditions. Ochratoxin A is a toxic fungal metabolite that may cause nephrotoxic, teratogenic, immunosuppressive and carcinogenic effects in many species.
