Cars emit a variety of toxic substances, primarily through their exhaust systems. Key pollutants include:
Carbon Monoxide (CO): A colorless, odorless gas that can cause serious health effects by reducing oxygen delivery to the body's organs. Nitrogen Oxides (NOx): Contribute to respiratory problems and the formation of smog and acid rain. Particulate Matter (PM): Tiny particles that can penetrate deep into the lungs and even enter the bloodstream. Volatile Organic Compounds (VOCs): Contribute to the formation of ground-level ozone and can cause various health problems.
