Industrialization is a major force altering the environment for human habitation. Pollution from industrialization may pose new adaptive challenges for Homo sapiens as well as for other species. The study of human biological adaptation is a traditional area of physical anthropology, but until recently it has not focused on the adaptative challenges of the modern anthropogenic environment. By combining research from anthropology, epidemiology, and public health, it is possible to gauge some of the effects of pollution on human health and adaptation. This review focuses on human growth as a measure of health and a component of human adaptability. Considerable evidence now exists for an adverse impact of lead, noise, and polychlorinated biphenyls on human growth, either prenatal, postnatal, or both. There is substantial replication of results among studies, many of which differ in exposure assessment and classification, sample composition and size, and statistical techniques. Because of this amongstudy variation, specifying the exact amount of growth retardation due to a pollutant is difficult, but the direction and often the magnitude of the effect is similar across studies. There remain numerous barriers to more definitive research on environmental pollutants and health outcomes of importance to biological anthropologists. These are discussed also.Industrial pollution has rapidly and tremendously altered the environment for human habitation. Until industrialization, contaminant levels in the environment and in people were probably quite low. The possible exceptions are few. Lead from poorly fired pottery (Nriagu, 1983) and indoor air pollution from ineffectively drafted hearths (Eisenbud, 1978) may have been the main pollutants a t different times. With the development of craft specialists, occupational exposure began, and from this origin, pollutant levels grew with production. Compared to crafts techniques, industrialization represents a quantum leap in production and in contamination.The environment today contains new materials and old materials at concentrations much higher than people have ever encountered before. Exposure in the home and work place has become routine. A crucial feature of the new exposure pattern is that children are exposed also. The exposure may occur postnatally, or prenatally through passage of contaminants across the placenta. Human physical growth and development is known to be sensitive to a variety of environmental influences. Though early observations on the ecosensitivity of 0 1991 Wiley-Liss, Inc.

YEARBOOK OF PHYSICAL ANTHROPOLOGY[Vol. 34, 1991 growth may have been anecdotal, research over the last century has documented specific environmental features associated with variation in the pattern of human growth (Tanner, 1962;Bogin, 1988). The physical influences of temperature, hypoxia, and season of the year, as well as numerous social arrangements and characteristics, including parents' occupations and incomes, birth order, family size, and urban versus rural resid...
