What is PM2.5 and PM10? Effects on Human Health & Environment

PM2.5 and PM10

PM stands for Particulate Matter and it is also called particle pollution, which is a mixture of solid particles and liquid droplets present in the atmosphere. The particles that are present in the air are so minute that you cannot see with the naked eye. Some of the particles are so tiny that it can only be detected by using an electron microscope. Particle pollution includes, PM2.5 and PM10 are very dangerous. Here the former is a coarse particle that has the diameters of generally 10 micrometers and the latter is a very fine inhalable particle, with diameters of 2.5 micrometers and smaller.
PM2.5 is very fine dust particle and the size is 30 times smaller than a single hair which calculates about 60 micrometers in diameter and exposure to it is very harmful to your health.

Particulate Matters come in different sizes and shapes and it can be caused by both human and natural sources. The sources can be primary and secondary, where the primary include automobile emissions, dust, and cooking smoke. The secondary source of pollution can be complex reactions of chemicals like sulfur dioxide and nitrogen oxides. These particles mix in air and pollute it. In addition to these, forest fires, wood-burning stoves, agriculture burning, industry smoke, dust originated from construction works are few more sources of air pollution.

Health Effects of PM2.5 and PM10

Both PM2.5 and PM10 particles are so small that you cannot view through your naked eyes and they act as gas. When you breathe and penetrate deeply the PM particles into the lungs, you can experience a number of health impacts starting from coughing and wheezing to asthma attacks. You can also experience high blood pressure, heart attack, strokes and in serious condition, it can also result in premature death.

Some other health effects are mentioned below:

  • Shortness of breath
  • Irritation of the eyes
  • Tightness of the chest
  • Reduced lung function
  • Severe respiratory diseases
  • Irritation is eyes, nose, and throat
  • Irregular heartbeat and etc.

Who is at Great Risk?

Everyone needs air to breathe and in some way or other, they get exposure to air pollution by inhaling contaminated air. The study says that exposure to air pollution is higher in urban and industrial areas compared to rural areas. Besides, children and senior citizens are most likely to be badly affected by exposure the air pollution. People with heart and lung diseases are also at great risk to air pollution.

How Can You Reduce the Exposure of PM?

So, bring home the best air purifier and stay protected from the exposure of air purifier.


As the level of air pollution (PM2.5 and PM10) is rising high to the danger mark every day, you should ensure to stay protected from it You should take care of yourself so that you don’t become prey to air-borne diseases. Use a mask when you are outside and to breathe fresh air indoor make use of air purifier. Using of air purifier would minimize the risk of exposure to air pollution.
