What are the primary contaminants impacting air quality?
Air quality is compromised by various pollutants, primarily categorized into particulate matter (PM), volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3). Particulate matter, especially PM2.5, can penetrate deep into the lungs and even enter the bloodstream, causing cardiovascular and respiratory health issues. VOCs, sourced from industrial emissions and vehicular exhaust, contribute to the formation of ground-level ozone, which is detrimental to respiratory health.
