What are the 5 major air pollutants?

The common air pollutants are:
  • Particulate matter (PM10 and PM2.
  • Ozone (O3)
  • Nitrogen dioxide (NO2)
  • Carbon monoxide (CO)
  • Sulphur dioxide (SO2)

What is the most harmful pollutant?

Nitrogen Dioxide

NO2 is the most harmful of these compounds and is generated from the combustion of fuel engines and industry. It can damage the human heart and lungs and it reduces atmospheric visibility at high concentrations. Finally, it is a critical precursor to the formation of ground-level ozone.

What is the most common source of air pollution?

Most human-made air pollution comes from burning fossil fuels for transportation, electricity, and industry. Common pollutants produced by engines that burn fossil fuels are carbon dioxide, nitrogen oxides, sulfur dioxide, volatile organic compounds (VOCs), and particulates.

Exposure to air pollution can affect everyone’s health. When we breathe in air pollutants, they can enter our bloodstream and contribute to coughing or itchy eyes and cause or worsen many breathing and lung diseases, leading to hospitalizations, cancer, or even premature death.

Who is most affected by air pollution?

Older adults: Older people are more likely to be affected by air pollution, perhaps due to generally weaker immune systems, or undiagnosed respiratory or cardiovascular health conditions. As people age, their bodies are less able to compensate for the effects of environmental hazards.

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.

What health issues can pollutants cause?

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.
