Heavy metal detoxification wide variety of applications. Occupational exposure most often occurs in mining, extraction, and in the processing of alloy metals containing beryllium. Beryllium causes lung and skin disease in 2 to 10 percent of exposed workers. Cadmium is an extremely toxic metal commonly found in industrial workplaces, particularly where any ore is being processed or smelted. Several deaths from acute exposure have occurred among welders who have unsuspectingly welded on cadmium-containing alloys or with silver solders. Forms of hexavalent chromium can be toxic. Calcium chromate, chromium trioxide, lead chromate, strontium chromate, and zinc chromate are known human carcinogens. An increase in
Tube Alloys national leader to approve a nuclear weapons programme on 30 August 1941. The Chiefs of Staff Committee supported the decision. A directorate of Tube Alloys was established as part of Appleton's Department of Scientific and Industrial Research, and Wallace Akers, the research director of Imperial Chemical Industries (ICI), was chosen as its head. Anderson and Akers came up with the name Tube Alloys. It was deliberately chosen to be meaningless, "with a specious air of probability about it". An advisory committee known as the Tube Alloys Consultative Council was created to oversee its work, chaired by Anderson, with its other
