Carbon monoxide, for instance, is a colorless and odorless gas that is extremely toxic to humans and animals. It is produced when there is an incomplete combustion of carbon-containing fuels, often due to inefficient engine operation or faulty vehicle systems. High levels of CO can lead to reduced oxygen supply in the body, causing health issues, especially for individuals with cardiovascular or respiratory conditions.

Nitrogen oxides, on the other hand, are a group of highly reactive gases that include nitrogen dioxide (NO2) and nitric oxide (NO). These gases are formed at high temperatures during the combustion process. They contribute to the formation of ground-level ozone, a major component of smog, which is linked to respiratory problems and reduced lung function. NOx emissions also play a crucial role in the creation of fine particulate matter, which can penetrate deep into the respiratory system, causing irritation and inflammation.

Particulate matter, often referred to as PM, is a complex mixture of solid particles and liquid droplets suspended in the air. It includes a variety of substances, such as dust, pollen, smoke, and liquid droplets. PM is categorized based on its size, with PM10 and PM2.5 being the most common. The smaller the diameter, the easier it is for these particles to penetrate the respiratory system. PM2.5, in particular, can reach the deepest parts of the lungs and even enter the bloodstream, leading to various health issues, including respiratory and cardiovascular diseases.

To mitigate the impact of vehicle emissions, several measures can be implemented. These include adopting cleaner and more efficient combustion technologies, such as hybrid and electric vehicles, which produce fewer pollutants. Additionally, regular vehicle maintenance, such as tune-ups and emissions testing, can help ensure that engines are running efficiently and that pollutants are minimized.
