In this presentation we will deal with chemicals produced in the United States in excess of 1 billion pounds per year. It is presumed that chemicals produced in such high volume would be those most likely to present health hazards under certain conditions of exposure. A recent EPA document, Perspectives on the Top Fifty Production Volume of Chemicals July 1980, lists the Top 50 Chemicals. Although eleven of the top twelve are inorganic elements, mineral acids and bases or salts, 31 of the 50 are organic, mostly monomers of plastics, rubbers or fibers also fertilizers, antifreeze and intermediates. Xylene appears twice - once as mixed xylenes which is mostly meta and also as p-xylene, although toxic levels are not distinguished.
