Anthropogenic activities have drastically changed the biochemical cycles of heavy metals (HM) resulting in an elevated presence and availability of these elements in ecosystems and the urban environment. Six stations were selected for air sample collection for analysis .The method of field sampling is given according to manufacturer’s instructions booklet. Air quality with respect to SO2, NO2 and PM-10 has been determined in each site. Maximum concentrations of Zinc, lead, cadmium, copper and nickel were recorded at station four while minimum concentrations of lead, and zinc, were observed at station two. Maximum concentrations of chromium and Iron were observed at station three and minimum copper was recorded at station three. Maximum concentrations of manganese were recorded in station two and three and minimum concentrations of chromium were observed in station one and two. Levels of pollutant in residential areas and industrial areas were lower than the National Ambient Air quality Sources and EPA.
Key word: Ambient air, heavy metal, air pollution
