Abstract

Monitoring programme was conducted in Muna Valley during muslims pilgrimage period, 1402 H (1982 G). Measurements of sulphur dioxide, ammonia and particulates were carried out at the middle of the most busiest place in the valley. The rate of dustfall during pilgrimage period was 294 mg m-2 d-1 while its background rate was found to be less than 90 mg m-2 d-1. Concentrations of sulphates and tarry matter in dustfall were more than three times higher than their concentrations in dustfall over the area after pilgrims departure. Sulphur dioxide and suspended particulate were found associated at high concentrations enough to create health problems for those who are suffering from bronchitis and other chest troubles. High concentration of ammonia detected are possibly one of the prime causes of throat irritation during pilgrimage period. The results of the present work confirm that the atmosphere of Muna Valley is favoring the accumulation of pollutants to the limits causing adverse health effects for pilgrims. Control measures should be adopted and environmental planning for Muna Valley should be considered. These measures are urgently needed to avoid air pollution episodes in the valley during the occupancy of more than 2 million persons
