Sulfur Dioxide ([So.Sub.2]) Accumulation in Soil and Plant's Leaves Around an Oil Refinery: A Case Study from Saudi Arabia (Report) (Case Study‪)‬

INTRODUCTION Environmental pollution resulting from oil refineries is a worldwide concern. Petroleum hydrocarbon wastes leaked, emitted or even buried can cause severe damage to the biological system. A polluted area is characterized by; the high levels of emitted pollutants and organic compounds into the air, the high contamination levels of soil, plants and ground water and/or the possible movement of these contaminated matters to other areas(1). Part of the complexity of this problem is the conflict between the economical benefits of these refineries and its hazards to the public health and the surrounding environment. Air pollution usually causes severe negative effects on biota and serious health risks on the public living in the surrounding area(2),(3).
