Guidelines for Canadian drinking water quality : antimony : guideline technical document. : H144-13/28-2023E-PDF

"Antimony naturally occurs in the environment in the form of organic and inorganic compounds. Antimony enters the environment from natural sources and human activities, with coal combustion, mining and smelting being the most important sources of release from human activities. Canadians can be exposed to antimony via food, drinking water, air and consumer products. Exposure to antimony through environmental media, food and water is considered as low. Antimony may enter drinking water from plumbing solders in drinking water distribution systems. Food (including breast milk for infants), beverages and, to a lesser extent, drinking water are identified as the main contributors for exposure to the general population. Canadian data indicate that antimony is not commonly found in drinking water. The detection frequency for antimony in drinking water is very low and reported levels are largely below detection limits"--Executive summary, page 1.
