Distribution of Ammonia in the Jiddah Atmosphere

Abstract

Reports a comprehensive field study of atmospheric ammonia (NH⊂3) concentration which was conducted in Jiddah, Saudi Arabia (one of the fastest growing cities in the world) for the period 1984‐1987. Ammonia trends have been developed for five stations in Jiddah: daily, monthly and annual means, maximum and mean maximum reported. The average NH⊂3 concentration for 1984, 1985, 1986 and 1987 was 0.027 μl/l, 0.023 μl/l, 0.018 μl/l and 0.020 μl/l, respectively. A decrease in NH⊂3 concentration from 1984 to 1987 was observed. The four years′ average concentration was 0.022 μl/l and a maximum of 0.490 μl/l was recorded once at station 104 in 1984. The statistical significance of data and background information for air quality standards for the city are discussed. Analysis of data shows a lower mean than any international air quality standards.
