This review is derived in the main from a technical report of the same title prepared by the author in 1974 for The Aluminum Association, 750 Third Avenue, New York, N.Y. 10017, under the direction of Associated Water and Air Resources Engineers, Inc., Nashville, Tenn. The cooperation of both organizations is gratefully acknowledged, as is the assistance of Prof. Eric L. Morgan, Tennessee Technological University, in preparation of the original manuscript.
