A.

What are the health risks of sulfur dioxide?

What are the potential health effects of sulfur dioxide?
  • Inhalation: VERY TOXIC, can cause death.
  • Skin Contact: CORROSIVE.
  • Eye Contact: CORROSIVE.
  • Ingestion: Not a relevant route of exposure (gas).
  • Effects of Long-Term (Chronic) Exposure: May harm the respiratory system.
  • Carcinogenicity: Not known to cause cancer.
  • Why sulfur dioxide is harmful?

    It reacts easily with other substances to form harmful compounds, such as sulfuric acid, sulfurous acid and sulfate particles. About 99% of the sulfur dioxide in air comes from human sources. Sulfur dioxide is also present in motor vehicle emissions, as the result of fuel combustion.
  • Is sulfur dioxide a carcinogen?

    The one available animal study suggests that sulfur dioxide may be a carcinogen in mice. The International Agency for Research on Cancer (IARC) has classified sulfur dioxide as Group 3, not classifiable as to human carcinogenicity.
  • How can we reduce sulfur dioxide?

    Reducing acid rain. Sulfur dioxide can be removed from waste gases after combustion of the fuel. This happens in power stations. The sulfur dioxide is treated with powdered limestone to form calcium sulfate.
B.

Is sulfur dioxide safe to eat?

Sulfur dioxide might not sound good enough to eat, but this food preservative does make its way into a number of edibles, including dried fruits such as raisins, dried apricots and prunes. Sulfur dioxide is one type of sulfite, a preservative whose name might be more familiar.

  • Why Acid rain is a problem?

    Air pollution like sulfur dioxide and nitrogen oxides can cause respiratory diseases, or can make these diseases worse. Respiratory diseases like asthma or chronic bronchitis make it hard for people to breathe. The pollution that causes acid rain can also create tiny particles.
