Best of 10 Cities with Cleanest Air in the World

Air pollution is just one of the many problems the earth
is facing right now. It has been a major environmental
risk that affects millions of people leading to numbers of
fatalities and several diseases like stroke, heart
disease, lung cancer, chronic and acute respiratory
illnesses like asthma. The air we breathe is essential to
our body as it needs enough supply of oxygen in order to
maintain the healthiness of the organs and the systems of
the body.
Some countries already developed several policies to
reduce air pollution. But there are still numerous
industries and other factors that contribute to the
severity of the case mostly in the developing countries.

The most harmful pollutant called the PM 2.5 is a tiny
particle commonly found in soot, smoke and dust. This tiny
pollutant causes chronic lung illnesses when it has
penetrated the lungs.

The Particulate Matter (PM) is composed of sulfate,
nitrates, ammonia, sodium chloride, black carbon, mineral
dust and water. Usually, those with diameters less than 10
microns are already considered the most-harmful health
damaging particles that can severely affect the lungs,
according to the World Health Organization. However, there
are other factors that cause serious health problems from
air pollution aside from PM which includes the Ozone,
nitrogen dioxide, and sulfur dioxide.

Clean air has become minimal and in demand nowadays. As
people get sick every day, lives are also at stake due to
these pollutants hovering the air. Although we tend to
focus on the most polluted cities and countries in the
world, here is the list of the top ten cities with the
