An epidemiological study in US has shown that acute exposure to vehicle emissions over ten years period reduces lung function among tunnel officers Evans, (1998). A similar study confirms that there is a prevalence of chronic bronchitis and asthma in street cleaners exposed to vehicle pollutants in concentrations higher than WHO recommended guidelines, thus leading to significant increase in respiratory problems Rachou, (1995). Having viewed these consequences, the need to embark on research of this kind becomes obvious. This research work is intended to investigate the level of vehicular emission and air quality standard in a growing city Calabar, Nigeria. The knowledge from this investigation will assist authority in planning adequate pollution control measures. It is equally hoped that the study will generate interest on further research on the impact of vehicle emission on air quality and health implications in Calabar in particular and Nigeria in general for effective air quality control and management. 1.1. Traffic Emission in Developing Countries In most developing countries of the world vehicular growth has not been checked properly by environmental regulating authorities leading to increase levels of pollution. Traffic emissions contribute about 50-80% of NO2 and CO concentration in developing countries Fu (2001), and Goyal (2006). This situation is alarming and is predicated on the poor economic
