摘要：Boiler stack emissions were characterized and quantified for a tyre manufacturing company over a period of six months. The isokinetic sampling method was used. Variation of pollutant concentration as a function of distance from the emission source was also assessed. Results showed the major pollutants as sulfur dioxide, nitrous oxide carbon monoxide and particulates. Levels of sulfur dioxide ranged between 199mg/m3 and 233mg/m3; nitrogen dioxide between 59 and 99 milligrams per cubic meter (mg/m3); carbon monoxide between 54mg/m3 and 94mg/m3 and particulates between 212mg/m3 and 280mg/m3 during the sampling period. Levels of pollutants generally decreased during the sampling period. There was also a gradual decrease in the concentration of the pollutants with increasing distance from the epicenter with the highest levels being recorded at a distance of 300m for all pollutants
