A Systems Approach to Environmental Control

This paper illustrates the ways in which the environment problems besetting us today can be viewed using such closed-loop principles as transmission, coupling, shielding, and others very familiar to the systems engineer.It shows need within the industry for a fuller development of the systems philosophy in the handling of environmental problems and need for further automation in both environmental monitoring and environmental control. Analogies between control theory and Pollution control concepts are given, and several applications of the system concepts are provided in areas of shielding, filtering and collection. Needs for proper monitoring, standards, and early warning of serious conditions are also discussed.
