ABSTRACT

This chapter presents the Air management, Water management, Solid waste management, Health risk assessment and Hazard risk assessment. Gas absorption, as applied to the control of air pollution, is concerned with the removal of one or more pollutants from a contaminated gas stream by treatment with a liquid. The objective of any water quality management program is to control the discharge of any liquid pollutants so that water quality is not degraded to an unacceptable extent below the natural background level. More modern commercial operations, such as just-in-time or on demand manufacturing, call for reducing in-plant inventory to the absolute minimum possible, particularly with toxic, flammable, and explosive liquid waste. Volatile, hazardous, and toxic liquids may have to be stored under pressure. Many of the risks became apparent through various earlier studies involving cancer, and they have led scientists to utilize health risk assessments (HRAs).
