    This paper presents a statistical analysis of air quality monitoring in Nairobi city, at three major roads and Industrial Area, a site closer to the main industrial activities. The study was carried out using different gas analyzers and samplers. From the statistical analysis it was found that, there were extremely high values of black carbon which went beyond the upper limit of the instruments (50,000 Å‹g/m3) during the day on Ladhis road. Nakumatt Junction site recorded extreme values of Black carbon (14,008 Å‹g/m3) in the evening hours, while at Pangani Roundabout site, the diurnal mean value was extreme (14,446.5 Å‹g/m3) for the period. None of the four sites exceeded the WHO 24 h limit for both PM10 (50 μg/ m3) and PM2.5 (25 μg/m3). The 24 h mean values of PM10 in the three sites also did not exceed the ambient air.. View More»
