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
Environmental issues in Georgia pollutants monitored in Georgia include particulate matter (total suspended particulates [TSP]), carbon monoxide (CO), nitrogen oxides (NO2, NO), and sulfur dioxide (SO2). In Georgia the public transport system is not sufficiently developed. A significant proportion of the population uses private vehicles as the preferred mode of transport. The number of private vehicles has grown rapidly over the past decade and has almost doubled in the last five-year period. Traffic has increased followed by industrial sources. The country has seen a sharp rise in the number of old, dirty diesel vehicles on the road over the last decade and pollution testing
