Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air . These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.
What air pollution means?
Air pollution is a mixture of solid particles and gases in the air . Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it’s also called smog. Some air pollutants are poisonous.
What is air pollution and its causes?
Most of the air pollution takes place due to the burning of fossil fuels such as coal, oil, gasoline to produce energy for electricity or transportation. The release of carbon monoxide in high level indicates how much fossil fuel is burned. This also emits other toxic pollutants in the air.

What are major sources of air pollution?
There are four main types of air pollution sources: mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces.
What are the causes and effects of pollution?
High levels of air pollution can cause an increased risk of heart attack, wheezing, coughing, and breathing problems , and irritation of the eyes, nose, and throat. Air pollution can also cause worsening of existing heart problems, asthma, and other lung complications.
What are five effects of air pollution on humans?
Air pollution is considered as the major environmental risk factor in the incidence and progression of some diseases such as asthma, lung cancer, ventricular hypertrophy, Alzheimer’s and Parkinson’s diseases, psychological complications, autism, retinopathy, fetal growth, and low birth weight .
How can we identify air pollution?
Air quality is measured with the Air Quality Index, or AQI . The AQI works like a thermometer that runs from 0 to 500 degrees. However, instead of showing changes in the temperature, the AQI is a way of showing changes in the amount of pollution in the air. Air quality is a measure of how clean or polluted the air is.
What are the effects of pollution on human health?
Exposure to high levels of air pollution can cause a variety of adverse health outcomes. It increases the risk of respiratory infections, heart disease and lung cancer . Both short and long term exposure to air pollutants have been associated with health impacts. More severe impacts affect people who are already ill.
What is the biggest single cause of air pollution?
In terms of overall range and extents of impacts, however, it is my opinion that burning of fossil fuels (coal, gasoline, etc..) is the single largest source of air pollutants. These fuels cause smog, acid rain, soot and particulates increases, greenhouse gas emissions, and dispersal of some heavy metal contaminants.
