Kuwaiti oil fires — Air quality monitoring

Abstract

Abstract Just before the Gulf War was concluded in early March 1991, more than 700 wells in Kuwaiti oil fields were set on fire. About 6 million barrels per day of oil were lost in flames and a large number of pools and lakes were formed. Burning wells in Kuwait emitted several thousand tons of gases such as sulfur dioxide, carbon monoxide, hydrogen sulfide, carbon dioxide, and the oxides of nitrogen, as well as particulate matter, on a daily basis containing partially burned hydrocarbons and metals, all of which were potential for affecting human health and vegetation growth. This paper summarizes the real-time measurements of various gaseous pollutants in the Eastern Province of Saudi Arabia in Dhahran, Abqaiq, Rahimah, Jubail and Tanajib. The statistics on monthly variation of gaseous pollutants showed that pollution concentration in general was high in May 1991. The levels of typical pollutants such as sulfur dioxide (SO 2 ), carbon monoxide (CO) and nitrogen dioxide (NO 2 ) in the ambient air were much lower than the permissible limits defined in the Meteorology and Environmental Protection Agency (MEPA) standards. The pollutants measured during the Kuwaiti Oil Fires were compared with the corresponding values measured in the previous year. The comparison shows that although the concentration of gaseous pollutants were within the MEPA limits, during the period of oil well fires, the concentration level increased persistently which might have been harmful for human health. The harmful effects of the major pollutants on human health and vegetation are also briefly discussed in the paper.
