Approaches to determining reference values for biological monitoring for Chromium
Hexavalent chromium compounds are hazardous to health, and exposure should be well controlled to reduce the risks to workers’ health. Control of exposure often relies on personal protective equipment to prevent inhalation and dermal absorption. Biological monitoring has an important role in the assessment of exposure and the adequacy of its control. To aid the interpretation of the results of biological monitoring, there are guidance values produced by international organisations. Although the guidance values differ in basis and numerical value, they have many aspects in common. All are intended for occupational health professionals who can consider the results of biological monitoring in context, and use them to help reduce and control exposure.
