| The main atmospheric pollutants in Bangkok are total suspended particles (TSP), particle matter smaller than 10 microns (PM-10), carbon monoxide (CO), ground-level ozone (O3), nitrogen oxides (NOx) and sulphur oxides (SOx)-which contribute as greenhouse gases to global warming. Air pollution in Bangkok results from a combination of transport (diesel fuel) and industrial sources. SO2 Originates primarily from industrial processes. NOx and CO originate primarily from vehicles. TSP pollution is caused in large part by street dust blown from unpaved roads, open lands and eroded hillsides surrounding the city. Diesel buses and industrial sources also contribute significantly to PM-10 emissions. Conventional urban air pollutants are considered the most important problem. In addition, there is atmospheric pollution with toxic substances, such as hydrocarbons. This study contains the application of simple method for estimation of urban background pollution and the Street Pollution. Furthermore, a GIS-based is a model for automatic mapping of street pollution levels in an entire urban area. This method of city mapping is a powerful tool to investigate possible effects of street configuration on pollution concentrations in a city. |
