Sch-Chemical Deception

Lappe, professor of Health Policy and Ethics at the University of Illinois, here examines the public health crisis brought on by the proliferation of chemicals in the workplace, in agriculture and in medicine. Challenging a number of toxicological dogmas, he addresses the risks of carcinogens and teratogens (substances that adversely affect the fetus), delayed effects of exposure and the body's natural defenses. Lappe discusses the toxicity of heavy metals, solvents, radiation; environmental pollution caused by CFCs and carbon dioxide. He surveys drugs with toxic side effects--DES, thalidomide, oral contraceptives, steroids. He reminds us that contaminated drinking water is also a major concern. He argues that the ability of the planet and its people to cope with toxic substances has been overestimated. The material is fairly technical but the message is clear: we are all at risk. (Sept.)
