Air pollution continues to threaten the climate worldwide. Invisible particulate matters in the air are chemical, physical or biological agents that modifies the natural characteristics of the at-mosphere and contaminate the indoor or outdoor environment. Power plants, household combustion devices, automobiles and industrial production are common sources of air pollu-tion. The natural sources also exist and they include forest fires or volcanic eruption. Accord-ing to a World Health Organisation (WHO) assessment of the burden of disease due to air pollution, more than 2 million premature deaths each year can be attributed to the effects of urban outdoor air pollution. Pollutants of major public health concern are particulate matter (PM) and soot or Black Carbon (BC). They affect …show more content…

It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is emit-ted in both anthropogenic and naturally occurring soot. BC associated with premature mortali-ty and climate change enforce. [2]
PM10 contributes to the range of negative human health effects observed in urban environ-ments. Scientific researches show that long- and short-term exposures to fine particulate mat-ter, can cause premature death and bring harmful effects to the cardiovascular system, in-cluding increased prospect for heart attacks and strokes. Scientific evidence also links PM to harmful respiratory effects, including asthma attacks. There is a close quantitative relationship between exposure to high concentrations of small particulates (PM10 and PM2.5) and in-creased mortality. Contrary, small and reduced concentrations of those particulate matters, trim the number of related mortality. This allows a conclusion for population health improve-ments that could be expected if particulate air pollution is reduced.
By reducing air pollution levels, countries can reduce the burden of disease from stroke, heart disease, and lung
