This CD contains all the information needed to use potentially dangerous chemicals prudently. Arranged in alphabetical order by chemical name, this reference provides: synonyms, CAS numbers, and molecular and structural formulas. It covers natural and man-made sources of a substance, as well as its uses and various formulations. Each substance is categorized by physical and chemical properties, air pollution factors, water and soil pollution factors, and biological effects. Pesticides, detergents, phtalates, polynuclear aromatics, and polychlorinated biphenyls are all investigated in detail. The CD also features information on aquatic toxicity and biological effects, odor thresholds, sampling and analysis data, and structural formulas of over 3,000 chemicals. Tables have been refined to focus on environmentally related materials.
