Types of Harmful Car Emissions

The most common means of transport used today are cars. Their increased use has also increased the negative impact they have on the environment. Global warming is a worldwide challenge, and relevant authorities have confirmed that automotive emissions contribute significantly to degrading our environment.

Particulate Matters

These are particles which can be either visible or invisible depending on the size. Any particles of more than 10 micrometers in diameter are classified as particulate matters. They are part of the black carbon in car exhaust smoke and have both health and detrimental environmental effects. In humans, they trigger the development of respiratory disorders as well as cardiovascular related diseases. Gliding tires and brakes can also result into productions of toxic particulate matters.

Hydrocarbons (HC)

Hydrocarbons are the unburned fuel that escapes the combustion process. Under conditions of efficient fuel combustion, only water, and carbon dioxide results from the process. These two are nontoxic, but anything else arising from combustion of these fuels is harmful. Hydrocarbons are toxic and can cause asthma, liver diseases as well as different types of cancers.

Nitrogen oxides (NOx)

Oxides of nitrogen are nitrogen oxide (NO2) and nitrogen oxide (NO). Air is composed mostly of oxygen and nitrogen to a large extent. Under proper running conditions of an engine, nitrogen is oxidized into nitrogen oxide. Nitrogen oxide is not a friendly gas as it absorbs oxygen from the air and this can have detrimental effects as carbon monoxide. It also contributes to smog formation and formation of acidic rain.

Carbon monoxide (CO)

Carbon monoxide is a product of inefficient fuel combustion in diesel and petrol engines. CO when it combines with oxygen forms carbon dioxide. Thus under all conditions CO gas is dangerous if you get exposed to it. It inhibits red blood cells from releasing oxygen to the body as well as preventing it from absorbing more oxygen from the lungs. Prolonged exposures to this gas are fatal, and the best first aid action is to take the affected person in a place with an efficient circulation of air.

Sulfur oxide (Sox)

Fuels especially diesel contain sulfur and during its combustion, sulfur oxides are produced. Among them is sulfur dioxide which is a gas with an awful smell and also readily reacts with other substances in the environment to form very harmful products like sulfuric acid, sulfurous acid as well as sulfate particles.

Greenhouse Gases

Other gases which are not environmental friendly when produced in excess is carbon dioxide. It inhibits the normal functioning of living organisms especially in areas where there is no enough plants and vegetation to take up the carbon dioxide from the air.


If you notice your car is not properly burning the fuel; seek the services of a qualified mechanical technician. Take a personal initiative in creating a better tomorrow. Global warming is a threat to the health existence of our future generations. In extreme cases, poor environmental hygiene practices have been observed to contribute to congenital disabilities and physical disabilities.
