![]() Drinking water in the Netherlands contains hardly any or no chromium (VI). Foodstuffs do not contain chromium (VI) as this is converted into harmless chromium (III) before consumption. For these and for other consumer products such as cosmetics, cleaning agents, toys and tobacco, legal limits have been set and the health risks due to exposure are negligible. It can also occur in leather (as an impurity) and in cement. Chromium (VI) can also be released when welding stainless steel or when processing chrome-plated products such as taps. However, in practice, this exposure is so low that the associated health risks are very small. Exposure can occur when preserved wood is processed or burned. ![]() for play equipment, fences, and wooden garden structures). It is also sometimes used in preserved wood (e.g. The principal application of chromium (VI) is in rust-proofing paint. ![]() Sources of chromium (VI) in the living environment However, the exposure in work environments can be many times higher than elsewhere. We can all be exposed to small quantities of chromium (VI) in our daily lives. How can you come into contact with chromium (VI)? Every chromium (VI) compound has its own colour, specific composition and unique properties, varying in terms of particle size and their solubility in water, for instance. Chromium (VI) occurs primarily in the form of minerals and salts. We therefore always refer to ‘chromium (VI) compounds’.Ĭhromium (VI) compounds are generally made by humans for their rust-resistant properties. Chromate and dichromate ions are always associated with other substances such as zinc or sodium. After initially binding with oxygen, for example, chromium (VI) is primarily found as chromate and dichromate. Chromium (VI) is always formed as part of another substance and cannot exist on its own. Chromium is a metal that is found in various states of oxidation, such as chromium (III) and chromium (VI), also known as trivalent and hexavalent chromium respectively.
