What do you call the rain that contains chemical waste and causes damage to plants and animals?

Acid rain forms when sulfur dioxide and nitrogen oxides from fossil fuel combustion react with water vapor in the atmosphere to create sulfuric and nitric acids. These acidic compounds fall as rain, snow, or dry particles, damaging forest ecosystems, acidifying lakes, and harming wildlife. Smog refers to air pollution, while seasonal and monsoon rains are natural precipitation patterns without chemical contamination.
