| dc.description | The control of air pollutants from anthropogenic sources seem almost impossible due to numerous influencing factors present in the atmosphere. This study carried out a virtual mathematical experimentation using Matlab and analytical approximation to estimate the dimensional impact of initial pollutant plume cloud from a sudden volcanic blast and the dynamics of its wind field. The impact concentration (β) at the point source by the end of the first second (1.0s) was 3.0×105μgm-3 which implied a 99.5% sudden decay when compared to 0.01s concentration value at the emission point source, the corresponding vertical profile of aerosol content is 1.0×1032μgm-3. The study observed that air pollutants release from explosives/blasts get transported into the atmosphere in the first few seconds by forceful injection instead of by gradual dispersion as is the case with normal air pollutants plume releases. A mathematical control process was propounded (which is still subject to further research) to reduce the quick flow of air pollutants to immediate eruption vicinity. | |
