Abstract: Air samples from densely and less densely populated areas of Abuja Municipal Area Council, Kuje and Dobi Village in Gwagwalada Area council were analyzed using BW Technology GasAlaert® Microclip (gas detection instrument). The results showed varying concentrations of hydrogen sulphide, carbon monoxide and low explosive limit gases. The high concentrations of pollutants detected in Abuja municipal area council can be attributed to increased population growth, increased production of gaseous wastes and increased number of industries. However, no low explosive limit gas was detected in Kuje area council and with only emission of low explosive limit gases in Dobi, Gwagwalada area council which was due to decomposed refuse around the market and rice milling waste within settlements, in Dobi village.
