ABSTRACT
Albert Einstein said that the environment was "everything that is not me". Interesting and important chemical reactions occur in nature. Photochemical smog and acid rain are examples of chemistry in the atmosphere. Pollution problems in lakes, rivers, sediments, soil, and groundwater are caused by a failure to control the discharge of pollutants, either intentional or accidental. Contamination of soil and groundwater is caused by careless disposal and spills of chemicals. An important part of many soil and groundwater remediation projects is separating the pollutants from the natural media so they can be treated using the processes that are common for wastewater and gaseous emissions. Pollution prevention and control engineering involves the organization of artificial things to increase the level of health and happiness. The synthesis of pollution prevention and control systems involves linking reactors and separation processes in support of each other.
