Particulate matter is the sum of all solid and liquid particles suspended in air many of which are hazardous. This complex mixture includes both
organic and
inorganic particles, such as dust, pollen,
soot, smoke, and liquid droplets. These particles vary greatly in size, composition, and origin.
Particulate matter is a contributory and causative factor for many diseases.
There is even evidence that the Covid-19 and other viruses can be borne on
these particles. Environmentally, this pollution is a causative factor for
global warming. The following is a quote from
the World Health Organisation:
“Air pollution kills an estimated seven million people
worldwide every year. WHO data shows that 9 out of 10 people breathe air that
exceeds WHO guideline limits containing high levels of pollutants, with low-
and middle-income countries suffering from the highest exposures. WHO is
supporting countries to address air pollution.
From smog hanging over cities to smoke inside the home, air
pollution poses a major threat to health and climate. The combined effects of
ambient (outdoor) and household air pollution cause about seven million
premature deaths every year, largely as a result of increased mortality from
stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and
acute respiratory infections.”
Many scientific
studies have shown that PM2.5 pollution is responsible for reduced lung
function and capacity in children. This can lead to the development and exacerbation
of asthma and other pulmonary and cardiovascular diseases.
