The trace elements of environmental interest include antimony, arsenic, beryllium, boron, cadmium, chlorine, chromium, cobalt, copper, fluorine, lead, manganese, mercury, molybdenum, nickel, selenium, thallium, vanadium and zinc. The radioactive trace elements thorium and uranium can be added to this list. This document does not prescribe the methods used for the determination of individual trace elements.
