Coal pollution mitigation Since air is mostly nitrogen, combustion of coal often leads to production of nitrogen oxides. Sulfur dioxide and nitrogen oxides are primary causes of acid rain. For many years--before greenhouse gasses were widely understood to be a threat-- it was thought that these by-products were the only drawback to using coal. These by-products are still a problem, but they have been greatly diminished in most advanced countries due to clean air regulations. It is possible to remove most of the sulfur dioxide (SO), nitrogen oxides (NO), and particulate matter (PM) emissions from the coal-burning process. For example, various techniques are

Besides monitoring individual polluters, NEA also checks the ambient air quality for signs of pollution so actions may be taken to prevent any problem from worsening. Inspections on industrial and trade premises are also conducted on a regular basis to ensure that environmental regulations, such as the Environmental Protection & Management Act (Air
