which of the following is a primary air pollutant produced from burning coal?
The primary air pollutant produced from burning coal is sulfur dioxide (SO2). When coal is burned, it releases sulfur compounds present in the coal into the atmosphere. Sulfur dioxide is a harmful gas that contributes to the formation of acid rain and can also have negative effects on human health.
Sulfur dioxide is considered a primary air pollutant because it is emitted directly into the air from coal combustion. It can react with other compounds in the atmosphere to form secondary pollutants, such as sulfuric acid aerosols, which further contribute to air pollution and its harmful effects.
In addition to sulfur dioxide, burning coal also releases other primary air pollutants such as nitrogen oxides (NOx), particulate matter (PM), and carbon monoxide (CO). These pollutants have detrimental effects on air quality, climate change, and human health.
It is important to note that the emissions of these pollutants can be reduced through the use of cleaner technologies, such as flue gas desulfurization systems and the implementation of stricter emissions standards. Additionally, the transition to cleaner energy sources, such as renewables, can greatly reduce the environmental impact of coal burning.
