Support for building adequate capacities in the health sector at a national level is particularly needed, given that the health sector both uses mercury and is responsible for diagnosing, treating and preventing the health effects of mercury. The sector’s role in prevention is well recognized, and includes identifying the health effects and sources of exposure to mercury; setting reference levels of mercury in environmental media and food; phasing out mercury-containing devices in the health sector and phasing down the use of dental amalgams; and developing strategies, tools for action and guidance to support decision-making process. All of these aspects are covered by this educational course.
