520			_aABSTRACT The goal of this research work was to determine motor vehicle emissions contributions to air pollution at numerous locations in Lagos State, Nigeria. Ikorodu-Ketu, Festac Town– Iyana Oba, Toll gate Sango–Ijaiye, Oshodi–Iyana Ipaja and Lekki-Ikoyi Link Bridge were the locations which have been selected for this study. This research was done on suspended particulate matter and air contaminants namely carbon monoxide (CO), and sulphur dioxide (SO2) while others are nitrogen dioxide (NO2) and hydrogen sulphide (H2S). Carbon monoxide, nitrogen dioxide, hydrogen sulphide, and hydrogen sulphide in the air were detected using an equipment called the Kanomax Multi-Gas Detector 2700 Series. In order to quantify the suspended particulate matter, the TSI Aero Trak Handheld Particle Counter Model 9303 was used. The traffic observation was done during the peak-period of traffic congestion in these areas. The usual periods are between 8:00AM and 10:00AM in the morning while it is around 4.00-6.00PM in the evening. These were keenly observed for five (5) days i.e. from day 1 to day 5. A manual count was done at the various location in these hours and recorded. It was revealed that Ikorodu-Ketu has the greatest concentration of Carbon Monoxide (CO) substance in the morning with 49.00ppm and 83.00ppm and Oshodi- Iyana Ipaja has the highest in the evening with 60- 120ppm. The high accumulation of CO in IkoroduKetu and Oshodi-Iyana Ipaja can be attributed to the intensive automobile activity. Traffic flow influenced the amount of CO greatly in the area concentration of CO at places of free-flowing vehicles was lower than that for places with obstructed flow of traffic. This observation was gotten as a result of the statistical evaluation of the data collected from the sampling station. Through these observations, it was deduced that an increment in traffic congestions is a factor for increase in the concentration of air pollutants emitted by vehicles in Lagos. The study also revealed that there is a variation in urban air quality as a result of the fluctuation in vehicular movement and emissions. From the results obtained, all pollutants except H2S, showed a strong correlation with nature of traffic. It is however unfortunate that the pollutants that were measured in these areas surpassed and are above the standard of World Health Organization (WHO) for out-of-doors air quality.
