Contributions of CO, NO₂ and SO₂ from automobile emission to environmental problems in Niger state, Nigeria

This study assessed the contribution of automobile emission to CO, NO₂ and SO₂ in Niger state, Nigeria. Three research questions were formulated to guide the study. The research questions assessed the quantities of CO, NO₂ and SO₂ being emitted in the study area. Q-Rae Plus Multi-gas Monitor was used to collect the data on the quantity of CO, while the Q-Trak Plus IAQ Monitor was used to collect the data on the quantity of NO₂ and SO₂. Mean was the statistical tool used to answer the research questions. The findings revealed among others, that emission of CO, NO₂ and SO₂ from automobile in Niger State is higher than the minimum Federal Environmental Protection Agency standard. Based on the findings of the study, recommendations were made which among others include; Developing effective control of automobile emissions quality management programmes; improvement of motor traffic flow and control which requires good city road network; provision of reliable mass transport system which will reduce the number of vehicles and motor cycles on Niger State roads and therefore reduce emissions; and strengthening of the vehicle inspections and maintenance Department.
