Data collected at an urban area located on the costal line of the Arabian Gulf was analyzed to determine the seasonal variation and effects of three major primary pollutants. The pollutants chosen were methane (n-CH4), NOx and benzene. Methane and NOx were chosen since there sources cover a wide sector of the areas under investigation of urban development. Benzene was chosen for study since it is considered the primary airborne carcinogen with the highest cancer slope potency factor. The objective of the study is to determine over the three years period of investigation the trends of these gases and response to metrological and climatic conditions. It was found that dust adsorption had a great influence on methane ambient levels. NOx and benzene were greatly affected by each seasonal condition.
