(The EPA said acid rain occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere and transported by wind and air currents.) Because wind can blow acid rain’s components ...

One study found that acid rain in China may have even contributed to a deadly 2009 landslide. China is implementing controls for sulfur dioxide emissions, which have fallen 75 percent since 2007 ...

Acid rain is precipitation that contains harmful acids formed from air pollution, and it can damage ecosystems, structures, ...

Acid rain is primarily caused when sulfur dioxide, released into the air by the burning of coal, high-sulfur oil, and smelting and refining of metals, interacts with rain or fog. The acidic rain ...

Acid rain became a massive issue throughout the mid-1900s along the eastern coast of the United States. This was caused by the expelling of sulfur dioxide and nitrogen oxides into the air by coal ...

The State Environmental Protection Administration (SEPA) has warned that China's efforts to hold acid rain and sulfur dioxide (SO 2) at bay will fail if no further action is taken. It estimates ...

Acid rain is any form of precipitation where water and oxygen react with nitrogen oxide and sulfur dioxide to form acidic compounds. While natural causes such as volcanic eruptions can release ...

The term also refers to fog, hail or even dust that is acidic. Acid rain happens when sulfur dioxide and nitrogen oxides are emitted into the atmosphere and moved by wind and air currents ...

Our state is part of the region that consistently leads the nation in emissions of acid rain-producing sulfur dioxide and nitrogen oxides. Pennsylvania is a leader in acid rain in the U.S. Acid ...

Acid rain forms when water and oxygen in normal precipitation mix with chemicals such as sulfur dioxide and nitrogen oxides. The chemical reaction turns normal rain more acidic. Primary sources of ...
