Bleaching Agent: Sulfur dioxide can act as a reducing agent and is used as a bleaching agent in various industries, such as the paper and textile industries. Refrigerant: In its liquid form, sulfur dioxide was commonly used as a refrigerant in home appliances until being phased out due to its potential to harm the ozone layer.

Sulfur dioxide (SO 2) is a gaseous air pollutant composed of sulfur and oxygen. SO 2 forms when sulfur-containing fuel such as coal, petroleum oil, or diesel is burned. Sulfur dioxide gas can also change chemically into sulfate particles in the atmosphere, a major part of fine particle pollution, which can blow hundreds of miles away.

Uses of Sulphur Dioxide. In the food industries, as a food preservative. It acts as a bleaching agent to remove the excess chlorine and as a disinfectant. In cold storage plant, it acts as a refrigerant. It is used as a reagent and a solvent in the laboratory.

What are the harmful effects of SO 2? What is being done to reduce SO 2 pollution? What is SO 2 and how does it get in the air? What is SO 2? EPA's national ambient air quality standards for SO 2 are designed to protect against exposure to the entire group of sulfur oxides (SO x ).

Sulfur dioxide is used as a preservative found in many foods, including shrimp, pickled foods and, in particular, dried fruit. For people who are sensitive to the preservative or have asthma, the health risks of sulfur dioxide in …

Although its chief uses are in the preparation of sulfuric acid, sulfur trioxide, and sulfites, sulfur dioxide also is used as a disinfectant, a refrigerant, a reducing agent, a bleach, and a food preservative, especially in dried fruits.

Tweet. Sulphur dioxide. (also known as SO2, Sulfur Dioxide or E220) Why is Sulphur Dioxide used? It is sometimes used as a preservative for dried apricots and other dried fruits owing to its antimicrobial properties, (it is sometimes called E220 when used in this way.)

Abstract. 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.
