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 had largely disappeared. Beginning around 1990, the US and Europe passed legislation that limited the amount of acid-forming pollutants — such as sulfur dioxide and nitrogen oxides ...

Decades ago, acid rain was one of the world’s most ... Fortunately, governments passed laws to reduce sulfur dioxide and nitrogen oxide emissions. But now, there’s an even scarier problem.

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 ...

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 ...
