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 more people than other pollutants. The ma-jor components of PM are sulphate, nitrates, ammonia, sodium chloride, black carbon, min-eral dust and water. It consists of a complex mixture of solid and liquid particles of organic and inorganic substances suspended in the air [1]. In the range of different size of particulate matters the most important indicators of pollution in the air are particulate matters with equiva-lent diameter of 10 microns or less and of 2.5 microns or less, the so-called PM10 and PM2.5. Other pollutant - Black carbon (BC) consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is emit-ted in both
