Distribution of carbon monoxide in Jiddah atmosphere
Abstract A comprehensive field study of atmospheric carbon monoxide was conducted in Jiddah, one of the fastest growing cities in the world, for the period of 1984 through 1987. The carbon monoxide trends were developed for five stations scattered around the city of Jiddah. Daily, monthly, and annual mean, maximum and mean maximum concentrations are discussed. The average CO concentration for 1984, 1985, 1986 and 1987 was 1.48 μL/L, 1.90 μL/L, 1.51 μL/L and 1.96 μL/L, respectively. The four years average CO concentration was 1.71 μL/L and a maximum of 25.59μL/L was recorded once at station 101 in 1984. Despite the annual increase in the number of cars, the annual mean of the four years almost remained unchanged. However, a decrease in CO maximum and mean maximum concentrations from 1984 to 1987 was observed. This decrease was mainly due to the phasing out of many construction and industrial projects and the enforcement of the Motor Vehicle Periodic Inspection (MVPI). The statistical significance of data and proposed air quality standards for the city are discussed. Analysis of data shows lower mean than any international air quality standard.
