“…These values can be attributed to high vehicular tra c during these periods as earlier reported (Ibe, Opara, Njoku et al, [7]. It can be also seen from the results that CH 4 emissions were usually high during the am peak period; this is likely not unconnected to the presence of Olusosun dumpsite which is the largest dumpsite in Africa (see Ahove,Ojowuro & Okafor,[2]) about 3km away from the motor park. In addition to this, the relative humidity was also highest at this period of time.…”

Over the years, scientists have established that when fossil fuels are burnt, the resultant effect is pollution of the ambient air with pollutants such as carbon monoxide (CO), methane (CH4), oxides of nitrogen (NOX), oxides of sulfur (SOX), volatile organic hydrocarbons and particulate matter and atmospheric greenhouse gases such as carbon dioxide (CO2) and methane (CH4) and heat-warming or cooling aerosols such as black soot and sulfate aerosols, respectively. These pollutants become present in the atmosphere at a concentration that can affect human health, the environment, and even society as a whole. Since around 1750, human activities have increased the concentration of CO2 and other greenhouse gases in the atmosphere by many tens of percent over the last two centuries. The Federal Government of Nigeria, through the office of National Environmental Standards and Regulation Enforcement Agency (NESREA), established guidelines and standards (limits) for the abatement and control of all forms of pollution through the establishment of Nigerian Ambient Air Quality Standards (NAAQS). Different studies on the impacts of urban road transportation on ambient air quality carried out by scholars have suggested that most pollutant gases in the atmosphere are traffic-related as a result of the combustion of petroleum-based products like gasoline and diesel in internal combustion engines. This study deployed a quantitative technique to determine the emissions profile of transport nodes in Ikeja, Lagos through the use of AEROQUAL 500s portable air monitoring equipment. Results showed that CO, CO2 and CH4 emissions were highest during the AM peak and PM peak periods and lower during the inter-peak period, while NOx emissions were relatively stable throughout the time periods.
