Effects of Sulfur Dioxide
• On the Environment:
Sulfur dioxide emissions when released into the air, make their way into cloud water droplets. These sulfuric acid droplets are one of the causes of summertime haze, and are also the precursor to acid rain. As the Sulfur Dioxide reacts with water (shown in reaction below), Sulfuric acid is formed within the tiny cloud water droplets. While some of the sulfuric acid particles fall as "dry" acid deposition, the tiny water droplets containing sulfuric acid continues to attract more molecules of water to form larger droplets of dilute sulfuric acid. This causes the rain to become acidic, and the acidic pollution can be transported by wind over many hundreds of miles, and deposited as acid rain. The acid rain, would in turn, affect the pH level of structures, but mostly soil and water, thus affecting the ecosystem, as the right pH condition of the soil is a component which determines the growth and abundance of plants, the very base of the food chain.
Acid Rain: SO2 + H2O -> H2SO3
