What are the health effects from acid rain?
Acid rain does not directly affect human health. But the main components of acid rain — sulfur dioxide and nitrogen oxides — do. These gases contribute to particulate pollution, which can affect the heart and lungs. High levels of sulfur dioxide can aggravate lung and heart diseases. Nitrogen oxides increase levels of ground-level ozone, react with other chemicals to form toxins, and contribute to global warming.
