Mercury is considered by WHO as one of the top ten chemicals or groups of chemicals of major public health concern. Both high level/short term and low level/long term exposures can lead to serious health problems.

Elemental mercury is toxic primarily through inhalation of mercury vapours. It is only slowly absorbed through the skin, although it may cause skin and eye irritation. Elemental mercury droplets may be absorbed through eye contact.

Average Value of Exposure = 20μg/m3 (Daily exposure value, standardized for a 8-hour reference period).

Mercury can be present in various equipment, laboratory rooms, furniture, HVAC system…

A diagnosis is then crucial.
