👉 Taxi fumes refer to the pollutants and harmful substances released into the air by vehicles, particularly those using combustion engines like traditional taxis. These emissions include carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), and volatile organic compounds (VOCs). CO is a colorless, odorless gas that can be deadly in high concentrations, while NOx contributes to smog and acid rain. Particulate matter, especially fine particles (PM2.5), can penetrate deep into the lungs and bloodstream, causing respiratory and cardiovascular issues. VOCs react with NOx in the presence of sunlight to form ground-level ozone, another harmful pollutant. These fumes not only degrade air quality but also pose significant health risks to both drivers and passengers, especially in urban areas with high traffic density.
