Abstract
On the basis of information in the technical literature, the values and dangers deriving from trace metals in the environment are discussed. Particular attention is given to metals as airborne contaminants. Beryllium, antimony, bismuth, tin, nickel, cadmium, lead and mercury are counted as occupational medical problems in the industrial environment. Other than such occupational exposures, trace metals in the air are not currently threatening the health of the public.
