"Sulfur dioxide, SO2 gase exposure effects & limits
Sulfur Dioxide Gas Exposure Hazards & Effects. For sulfur dioxide (SO 2)the TLV had been 5.0 ppm for many years, but in 1978 ACGIH announced its intention to reduce that TLV to 2.0 ppm; that was done in 1980. The reason for this was recent information indicating that chronic (long term, repeated) exposure to sulfur dioxide concentrations near 5 ...

Sulfur dioxide is a colorless gas with a pungent odor. It is a liquid when under pressure, and it dissolves in water very easily. Sulfur dioxide in the air comes mainly from activities such as the burning of coal and oil at power plants or from copper smelting. In nature, sulfur dioxide can be released to the air from volcanic eruptions.
