kéntidioxidot

Kéntidioxidot, chemically known as sulfur dioxide, is a chemical compound with the formula SO2. It is a colorless gas with a pungent, irritating odor. Sulfur dioxide is a naturally occurring substance, produced by volcanic activity and industrial processes such as the burning of fossil fuels. It is also a byproduct of certain industrial activities, including smelting and paper production.

In its gaseous form, sulfur dioxide is denser than air. It is soluble in water, forming sulfurous acid, which is a weak acid. This acidity plays a significant role in its environmental impact. Sulfur dioxide is a major air pollutant and a primary contributor to acid rain. When released into the atmosphere, it can react with water, oxygen, and other chemicals to form sulfuric acid. Acid rain can damage forests, harm aquatic ecosystems, and corrode buildings and monuments.

Human exposure to sulfur dioxide can cause respiratory problems, particularly for individuals with asthma or other lung conditions. Symptoms can include coughing, wheezing, and shortness of breath. High concentrations can be dangerous. Due to its health and environmental effects, regulations are in place in many countries to limit sulfur dioxide emissions from industrial sources. Despite its negative impacts, sulfur dioxide also has some industrial applications, such as a preservative in food and beverages and as a bleaching agent.
