( ) EINECS: European Inventory of Existing Chemical Substances.
( 2 ) CAS: Chemical Abstract Service Registry Number.
( 3 ) A skin notation assigned to the occupational exposure limit value indicates the possibility of significant uptake
through the skin.
( 4 ) Measured or calculated in relation to a reference period of 8 hours time-weighted average (TWA).
( 5 ) Short-term exposure limit (STEL). A limit value above which exposure should not occur and which is related
to a 15-minute period unless otherwise specified.
( 6 ) mg/m 3 : milligrams per cubic metre of air at 20°C and 101.3 KPa.
( 7 ) ppm: parts per million by volume in air (ml/m 3 ).
( 8 ) Existing scientific data on health effects appear to be particularly limited
( 9 ) When selecting an appropriate exposure monitoring method, account should be taken of potential limitations
and interferences that may arise in the presence of other sulphur compounds.
( 10 ) The mist is defined as the thoracic fraction.
( 11 ) During exposure monitoring for mercury and its divalent inorganic compounds, account should be taken of
relevant biological monitoring techniques that complement the OELV.”.
