 Justify “Dust is a pollutant”?

Answers (1)

The air we breathe indoors and outdoors always contains particle pollution. Some particles, such as dust, dirt, soot, or smoke, are large enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope. Dust particles, often referred to as particulate matter (PM), in the atmosphere arise from a wide variety of sources. Given the wide variety of pollutants and chemical compositions involved, dust particles play a role in many air pollution issues.

  • Human health effects of particles respiratory and heart problems caused by inhalation of small particles have been related to the mass concentration of particles below 10 µm diameter.
  • Deposition of regional pollutants causing acidification and eutrophication.
  • Breathing low levels of household or urban dust does not cause health problems in most individuals but anyone who is exposed to high levels of dust may be affected – the longer you breathe in the dust, then the greater the chance that it will affect your health.
  • The Department of Health recommends that you think about using dust control and personal protective equipment whenever you undertake dusty activities at home or at work.
  • People more likely to develop health problems from long-term exposure to high levels of dust include: babies and young children, elderly people (65 years and over), people with pre-existing respiratory conditions (e.g. asthma, bronchitis), including smokers, heart conditions
