Acute/short term exposure
Hazard assessment conclusion:
no data available: testing technically not feasible
DNEL related information

Local effects

Long term exposure
Hazard assessment conclusion:
no data available: testing technically not feasible
Acute/short term exposure
Hazard assessment conclusion:

Workers - Hazard for the eyes

Local effects

Hazard assessment conclusion:
high hazard (no threshold derived)

Additional information - workers

DNEL values for inhalation have been derived based on dihydrogen sulfide, the most toxic and volatile constituent of green liquor. The sulfides, (mono)sulfide, hydrogensulfide and dihydrogen sulfide are major toxic constituents of Green liquor and therefore it is justified to use read across information and utilize relative large dataset available for volatile sulfides/soluble sulfide salts.

Local effects

Hazard assessment conclusion:
high hazard (no threshold derived)

Additional information - General Population

DNEL values have not been derived for general population because of the exposure considerations. Green liquor is used entirely in industrial processes, as an intermediate in pulp mills (IPC sites) and in basic metals industry (IPC sites), and no exposure to general population is expected.
