How to limit the damage caused by air pollution to health

air pollution

For people in most parts of the world, air pollution is just a tolerable circumstance that does not cause immediate harm. But the reality check is that, air pollution is as dangerous as any other disease. The horror stories about China’s pervasive air pollution which costs the life of more than one million people every year are shocking and show no signs of improvement.

Considering the rapid urbanization, the question of how worse air pollution could get in near future is out of imagination and the only practical solution we can possibly implement right now is taking a personal commitment of playing our part in reducing air pollution and limiting the risk and the damage caused by it to our health.

The impact of air pollution on health

The Four key pollutants that can cause health risks if it exceeds the limits set by the WHO are particulate matter (PM), ozone, nitrogen dioxide and sulphur dioxide.
Nitrogen di oxide has a negative effect on lung function, especially in children with asthma. It is caused by the burning of fuels and heat. Sulphur dioxide is a colourless gas released when sulphur-containing fossil fuels are burned to produce heat and power. It causes High levels cause eye irritation, breathing difficulties and respiratory related problems.

PM 2.5

Particulate matter, in particular, affects more people than any other pollutant. It is a mix of solid and liquid particles suspended in the air and the smaller the particle is, the worse it is. The most health-damaging particles are those with a diameter of 10 microns or less, (PM10), which can penetrate and lodge deep inside the lungs. Chronic exposure to particles contributes to the risk of developing cardiovascular and respiratory diseases, as well as of lung cancer,” says the WHO.

However, recently there has been an increase in the concentration of PM 2.5 (Particulate matter less than 2.5 micron in size). These PM levels are particularly dangerous as it is so tiny that it could directly enter the lungs or blood stream by mere breathing.

As of the Words Heath Organisation’s extensive studies, here are a list of the best and worst nations for air pollution around the world in 2017. All units displayed in this table represent levels of PM2.5.


The major sources of PM are

  • vehicles
  • power generators
  • industrial and agricultural emissions
  • residential heating and cooking
  • the manufacture and distribution of chemicals
  • forest fires

Self- prevention tips to limit the damage

3. Air filtering plants- your air care buddy

Given that people spend more than 90 percent of their time indoors, air quality matters . Furnishings, upholstery, synthetic building materials, and cleaning products in homes and offices can emit a variety of toxic compounds, like formaldehyde. Indoor air pollution can also be caused by pollen, bacteria, and molds, as outdoor air contaminants like car exhaust finds its way into buildings. The good news is there is a solution to beat the inside pollution and it comes from the natural world. Plants absorb some of the particulates from the air at the same time that they take in carbon dioxide, which is then processed into oxygen through photosynthesis. But that’s not al, microorganisms associated with the plants are present in the potting soil which are also responsible for much of the cleaning effect.
