Air Pollution from Combustion Engines

Combustion engines, prevalent in vehicles and industrial machinery, emit harmful pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM). These emissions significantly degrade air quality and pose serious health risks.


Impact of Industrial Activities on Air Quality

Industries are major contributors to air pollution due to their extensive use of fossil fuels and production processes. The release of pollutants such as sulfur dioxide (SO2) and volatile organic compounds (VOCs) from industrial activities significantly deteriorates air quality, impacting both human health and the environment.
