In the environment, organisms including man are exposed to mixtures of chemicals rather than single compounds. Examples of mixtures are food and feedstuff, pesticide and medical products, dyes, cosmetics, and alloys. Many other commercial products, such as printing inks, contain a mixture of substances, possibly up to 60 individual chemicals in 1 formulation. Preparation of these chemicals may involve the use of several hundred other substances in upstream processes.
