Air pollution is a mixture of solid and gaseous particles in the atmosphere. The solid and gaseous particles always consist in air, but pollution means an excessive amount of these particles which result in contamination of the air.
The solid particle in the air mostly consist of dust and gases consist in are are mostly CO2, carbon monoxide, carbon dioxide, methane, chlorofluorocarbons, nitrous oxide. These pollutants which adulterating the air can even cause health issues. This can result in severe disease and even death in many cases.These air pollution has natural reason and also happens due to human impact.
Natural causes of air pollution:
Natural causes of air pollution consist of volcanic eruptions and forest fires. The volcanic eruption doesn’t happen all the time but when happens, it can have a major impact on the local region and even slight impact on atmosphere and other regions. Volcanic eruption mostly erupts pollutants like sulphur dioxide, carbon dioxide, hydrogen fluoride. In which, sulphur dioxide is the gas which causes acid rain.
Plus Volcanic also emit volcanic ash and can travel thousands of miles and can cause respiratory problems, especially to the young children and also to the people having respiratory issue already. It can also lower the land temperature by blocking the sun rays and also leads to climate change.
Another source as mentioned above for natural pollution is forest fires. forest fires emit carbon monoxide, sulphur dioxide, nitrogen dioxide, ozone, and particulate matter. Carbon monoxide, which is a poisonous gas, can be emitted in large amounts during forest fires.
Particulates, which are mixtures of soot, tars, and volatile organic substances, either solid or liquid, are emitted in large quantities from forest fires. The particulates, which can be smaller than 2.5 micrometers in diameter, if deeply inhaled into the lungs, can damage lung tissues and cause respiratory and cardiovascular problems.
Although, there are also other natural sources of pollution but the impact is very less.
Human causes of air pollution:
Emissions from industries and manufacturing activities is one of the leading contaminator of air which can cause air pollution. These industries consist of waste incinerated which burn waste no matter what in it which can even burn heavy metal, plastics which are very hazardous. The manufacturing industries also emits high levels of carbon monoxide, organic compounds, and chemicals into the air. Petroleum refineries also release lots of hydrocarbons into the air and they are greenhouses causes global warming.
Transportation is also one of the biggest contributors of air pollution in the atmosphere especially after industrial era. The vehicle which are used in transportation are mostly uses fossil fuel. Thus, these vehicles emit dangerous gases such as carbon monoxide, oxides of nitrogen, hydrocarbons and particulates.
The other pollutant are household and farming pollution. Crop dusting, fumigating homes, household cleaning products or painting supplies, over the counter insect/pest killers, fertilizer dust emits harmful chemicals into the air and cause pollution. In many cases, when we use these chemicals at home or offices with no or little ventilation, we may fall ill if we breathe them.
