Environmental agencies have been imposing more and more stringent discharge limits on industries involved in processes using metal ions. Numerous industries produce aqueous effluents con taining metal ions and particularly copper and cadmium. Copper sulfate is used on a large scale in the electroplating industries. In addition, copper salts are used as fungicides, timber preservatives, insecticides, paint corrosion inhibitors and in dyestuffs. Cadmium is used...

Environmental Biotechnology is an emerging field of scientific and technological investigations that is truly global. People around the world are now joined together by a common technical bond. Furthermore, popular recognition is high for the environmental problems being faced and solved by biotechnology methods. With a feeling of winning, but recognizing there is much work to be done, workers with in-depth experience in solving one problem in environmental biotechnology meet to learn from the background of other workers how they, too, are addressing and solving environmental problems.
