Abstract: This study was conducted to assess the meteorological parameters and their influence on the air pollutants in the study area using portable handheld meters. The level of air pollutant concentration depend not only on the quantities that are emitted from air pollution sources but also on the ability of the atmosphere to either absorb or disperse these emissions. The research showed that meteorological parameters had significant effects on air pollutants and there was also poor linear relationship on the air pollutants. Geographical and meteorological conditions of the study area can also influence some local background concentration of air pollutants since there is a relationship between air pollution and meteorological variables.In view of this, therefore, atmospheric pollutant conditions most often are subjected to spatio-temporal variations causing the air pollution pattern to change with space and time due to changes in meteorological and topographical conditions. The aim of the study was to assess existing meteorological variables as they influence the air quality status in the study area.

Introduction The absence of proactive environmental laws/regulations and ineffective enforcement of the existing laws and regulations create a big gap in air quality management (Ahove, 2006; Olowoporoku, 2011). Several studies have reported that residents of refinery areas, commercial squares, traffic junctions and residential areas which are densely populated suffered adverse effect of PM 10 and associated high rate of respiratory diseases in most cities in Nigeria (Okecha, 2000; Efe, 2005 and 2006; Gobo et al., 2012; Kochubovski and Kendrovski, 2012; Antaiet al., 2016). Existence of man with respect to sustainable development society requires proper management and preservation of the environment through adequate knowledge of the changes in the air quality status of the environment and proposed mitigation measures (Bhatia, 2011).This is hinged on space variation of sources as well as atmospheric gradients which most often results in the diffusion and transportation of the pollutants to areas outside the source of the air pollution. Atmospheric dynamics which are generally controlled by meteorological factors (including temperature, air pressure, humidity, wind speed and direction, etc) remarkably influence the tendency for the release of atmospheric toxins to the environment.

Materials And Methods Nature/Sources of Data Seven (7) selected sampling points were measured during data collectionfrom the primary sources in the study area to assess the meteorological parameters.
