Sulphur dioxide is widely used in the food and drinks industries for its properties as a preservative and antioxidant. Whilst harmless to healthy persons when used in recommended concentrations, it can induce asthma when inhaled or ingested by sensitive subjects, even in high dilution.

The Unseen Hazards of Wastewater Treatment Plants

The main gases of concern in wastewater treatment plants are methane, hydrogen sulfide, and oxygen (or the lack thereof). Hydrogen sulfide and methane are the byproducts of the decomposition of organic materials that exist in the waste flows feeding the plant. The buildup of these gases may lead to the lack of oxygen, or in some cases ...

MATERIAL SAFETY DATA SHEET (MSDS) SULPHUR DIOXIDE

Sulphur dioxide dissolves in water forming sulphurous acid, which is unstable toward heat. In many of its reactions, sulphur dioxide behaves as a reducing agent. Biological Hazards Liquid Sulphur dioxide may cause skin and eye burns upon contact with these tissues, which results from the freezing effect of the liquid on the skin or eyes.

Sulfur Dioxide - an overview | ScienceDirect Topics

Sulfur dioxide has a direct impact on human health and is responsible for a variety of respiratory problems (Table 4.10).Like most air pollutants, sulfur dioxide poses a greater threat to sensitive groups such as the elderly, asthmatics, and young children. By contributing to acid rain, sulfur dioxide can have significant impacts on plants, surface waters, and buildings.
