Sõidukiemissioonid

Sõidukiemissioonid refers to the emissions produced by vehicles. These emissions are a significant source of air pollution, impacting both human health and the environment. The primary pollutants from vehicle emissions include carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), hydrocarbons (HC), and carbon dioxide (CO2).

Carbon monoxide is a colorless, odorless gas that can reduce the oxygen-carrying capacity of blood. Nitrogen oxides contribute to the formation of smog and acid rain, and can also irritate the respiratory system. Particulate matter, consisting of tiny solid or liquid particles, can penetrate deep into the lungs and cause respiratory and cardiovascular problems. Hydrocarbons are volatile organic compounds that contribute to smog formation. Carbon dioxide is a greenhouse gas that plays a major role in climate change.

Regulations and technological advancements have been implemented to reduce vehicle emissions. Catalytic converters are a common exhaust emission control device that converts toxic pollutants into less harmful substances. Modern vehicles are designed with improved fuel efficiency and more advanced emission control systems. Alternative fuel vehicles, such as electric and hybrid cars, are also gaining popularity as they produce significantly fewer or no tailpipe emissions. Monitoring and controlling vehicle emissions remain crucial for improving air quality and mitigating climate change.
