Document Summary
Chapter 10: body burdens of industrial chemicals in the general population: Petroleum and other materials are transformed by industrial processes into fuels, plastic, pesticides, cosmetics, food additives and pharmaceuticals. Residues of human made substance can now be found in the air, soil, water and food web in the most remote reaches of the plant. Pollutants that are distributed ubiquitously result in universal human exposure through inhalation, drinking water, and the food supply. Some of the substances to which the general human population is exposed resist metabolism and excretion and therefore accumulate in body tissues. The quantity of an exogenous substance or its metabolites that has accumulated in an individual or population is defined as a body burden. Individual"s body burden of a pollutant is estimated by measuring the concentration of that substance in one or more tissues, usually by gas chromatography/mass spectrometry.
