title: Environmental politics and science: the case of PBB contamination in Michigan.
abstract: This article examines how politics and science interacted against a background of uncertainty to shape policy in the case of environmental contamination by polybrominated biphenyls (PBB) in Michigan. In 1973, between 500 and 1,000 pounds of the flame retardant PBB were accidentally shipped and used instead of the dairy feed additive magnesium oxide, resulting in the widespread contamination of animal feeds, animals, and human food products. The contamination was initially perceived as the private trouble of a single farmer. The problem next became a public issue as public and private institutions grappled with questions of illness, safety, and disposal. To gain influence over those institutions, dissatisfied individuals and groups then turned the PBB contamination into a political controversy. The final section of the present article analyzes how science and politics interacted in: the ways bureaucratic organizations defined the three problems of contamination; the role political controversy played in redefining problems and influencing policy; and the political roles of scientists in controversies over environmental contamination.
