👉 Car fumes are a mixture of volatile organic compounds (VOCs) and other pollutants emitted from vehicles, primarily due to incomplete combustion of fuel and the breakdown of materials inside the engine. These emissions include carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC), and particulate matter (PM). CO is particularly dangerous as it can reduce oxygen in the blood, while NOx contributes to smog and acid rain. HC can also form ground-level ozone, a harmful air pollutant. Particulate matter, especially fine particles (PM2.5), can penetrate deep into the lungs and even enter the bloodstream, leading to respiratory and cardiovascular issues. Regular exposure to car fumes can exacerbate existing health conditions and pose significant risks to public health, especially in urban areas with high traffic density.
