Causes of Air Pollution
The presence of hazardous substances in the atmosphere, which are largely created by human activity, causes air pollution. It can also occur as a result of natural events such as dust storms, volcanic eruptions, and wildfires, which wreak havoc on the air quality.
The following are some of the origins of air pollution:
- Emissions From Factories and Industries- Industries and factories pollute the air by releasing large amounts of carbon monoxide, chemicals, hydrocarbons, and other organic substances.
- Fossil Fuel Combustion- Sulphur dioxide and nitrogen are produced when fossil fuels such as oil and coal are used for electricity and road traffic.
- Waste Production- Methane production in landfills is usually to blame.
- Agricultural Activities- One of the most dangerous chemicals released during agricultural activity is ammonia. Insecticides, pesticides, and fertilisers pollute the atmosphere by releasing toxic chemicals.
- Mining Activities-The minerals beneath the earth’s surface are retrieved utilising enormous pieces of equipment during the mining operation. The dust and chemicals emitted during the operation not only contaminate the air, but also harm the employees’ and local residents’ health.
- Domestic Sources- Toxic chemicals are emitted into the air by household cleaning products and paints. The odour emanating from freshly painted walls is due to the chemicals inherent in the paints. It not only pollutes the air, but it also makes it difficult to breathe.
What is Air Pollution? Definition, Types, Causes, Prevention
The negative changes that are taking place in our environment and how they are affecting our lives. Pollutants are substances that contaminate the air and water. Natural sources of pollution include smoke and dust from forest fires and volcanic eruptions. Man-made pollution includes power plant and automotive emissions, as well as the burning of firewood. The principal air pollutants include carbon dioxide, nitrogen oxides, carbon monoxide, methane, and Sulphur dioxide. Global warming is caused by rising carbon dioxide levels.
