Also a by-product ofoil refining and burning. The gas smells of rotten eggs and in highconcentrations can kill or cause illness.Having a strong aversion to water.A treatment technology involving destruction of waste bycontrolled burning at high temperatures.Integrated Pollution ControlIntegrated Pollution Prevention ControlExcavated or natural depression in the ground surface, forming animpoundment into which liquid material is placed.R&D <strong>Technical</strong> Report P5-042/TR/04iii
