Distribution of nitrogen oxides in Jiddah atmosphere
Abstract A comprehensive field study of atmospheric nitrogenous pollutants was conducted in Jiddah, Saudi Arabia, one of the fastest growing cities in the world, for the period of 1984 through 1987. Nitrogen oxide trends have been developed for five stations in Jiddah. Daily, monthly, and annual means, maximum and mean maximum are reported. The average NOx concentration for 1984, 1985, 1986 and 1987 was 0.053 μL/L, 0.039 μL/L, 0.024 μL/L, 0.030μL/L respectively. A decrease in NOx concentration from 1984 to 1987 is observed. This decrease is mainly due to two reasons, viz., 1) phasing out of many construction and industrial projects and 2) enforcement of the Motor Vehicle Periodic Inspection (MVPI). Since the phasing out of the projects has taken place smoothly, the observed reduction in the pollutant's concentration during 1985–1987 was attributed to the implementation of MVPI. The statistical significance of data and background information for air quality standards for the city are discussed. Analysis of data shows lower mean than any international air quality standard.
