Digital Analytical Study toward Air Pollution Effect Upon an Absorption Spectrum for Different Color Pigments

In urban centers, particulate matter and gaseous emissions as pollutant emissions from industries and auto exhausts are responsible for rising discomfort, increasing airway diseases and deterioration of artistic and cultural patrimony. The presented paper concerns with such topic; smoke effect inside a system designed for this purpose. In such system, a burning incense is used as a source for smoke emission to study its effect upon the absorption spectrum for an ink with different pigments. Results show an evidence to the concept of wavelength absorption/reflection attitude for an ink; ink absorbs the appropriate wavelengths to give rise the required color. The latter evidence is true for all colors expect for white/black pigments. The later pigments have identical curved lines for Red, Green, and Blue bands with a trough (high reflectivity)/peak (high absorption) respectively.
