Vitamin B12 could trigger outbreaks of acne, scientists have today warned. The essential nutrient, found in meat, fish, eggs and dairy products, as well as in Marmite, alters the activity skin bacteria. This leads to unsightly spots and pimples in susceptible people, a new study found.
Sulfur dioxide, SO2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead, and iron) that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid. Sulfuric acid is a major component of acid rain. Acid rain can damage forests and crops, change the acidity of soils, and make lakes and streams acidic and unsuitable for fish.
When fuel-containing sulfur, such as coal and oil, is burned and when gasoline is extracted from oil or metals are extracted from ore. When sulfur dioxide dissolves in water vapor to form acid and interacts with other gases and particles in the air, it forms sulfates and other products that can ultimately do what?
