supply of air or ventilation in their houses. During fire incidents‚ many people die because they sometimes inhale carbon monoxide that is poisonous for a human body. That is also a good way to find out if a person was alive or dead by the time the fire got to them; if they were dead before the fire got to them‚ they would not have certain inhalation burns or carbon monoxide (CO) in their blood.

air that can cause harm to humans and the environment. Pollutants may be natural or man-made and can be further classified as primary or secondary. Usually‚ primary pollutants are directly emitted from processes such as ash from volcanic eruption‚ monoxide gas from a motor vehicle exhaust or sulphur dioxide released from factories. On the other hand‚ secondary pollutants are not emitted directly rather‚ they are formed in the air when primary pollutants react or interact. Besides‚ some pollutants may

electrical signals. Air pollution is caused when air in the atmosphere is filled with particulate matter. The largest source air of pollution in cities is from vehicle exhaust fumes. Carbon monoxide is the largest air pollutant in the United States‚ and it’s number one source is from vehicle exhausts. Carbon monoxide is a poisonous‚ odorless‚ colorless gas that is formed when burning fossil fuels such as coal‚ petroleum and natural gas.

The most obvious cause for pollution in the air is the continuous augmentation of motorized vehicles that increase carbon monoxide in the air. This results in the de-purification of the air. Not as vast as motorized vehicles‚ but even more important‚ are the contents of smoke and gaseous residues that are injected into the atmosphere by the industries.essay on pollution.

increases the risk of coronary heart disease e.g. being overweight and having an unhealthy diet. Embracing an unhealthy lifestyle can also lead to heart disease‚ for instance‚ cigarette smoking. This is because carbon monoxide and carbon dioxide are present in cigarette smoke. Carbon monoxide combines with haemoglobin and therefore reduces the amount of oxygen transported in the blood resulting in a shortage of blood for the
