Chemicals: friends and foes.

There are many chemicals used in and around homes and workplaces that can result in accidents. Can it be said that the insecticides, drugs, polychlorinated biphenyls, DDT, asbestos, cleansers, cosmetics, and other chemicals are worth the price paid in terms of accidental poisonings? That is for the consumer to decide. Generally, it is the misuse of these chemicals that often leads to tragedy. Chemicals can be dangerous, but they can be advantageous when used with care.
