Environmental risk communication is examined as a community-based public health issue in this study. It provides data on information dynamics in six communities prior to the implementation of national community right-to-know legislation. It also provides a baseline for measuring changes in knowledge, attitudes, information gathering activities and other behaviors. Respondents (3,129) from six communities, Albuquerque, New Mexico; Cincinnati, Ohio; Durham, North Carolina; Middlesex County, New Jersey; Racine, Wisconsin; and Richmond, Virginia, provided information about recall of environmental risk information and sources, as well as personal knowledge, attitudes and behaviors related to environmental health risks. Local media are the most pervasive source of environmental information. Interpersonal sources were reported by fewer than 12% of the respondents. Credibility appears to be the most valuable attribute of an environmental information source. Credibility and expertise are perceived as independent characteristics by the public. More and more diverse information sources and higher levels of consumer interest are needed to involve the public effectively in environmental issues. Future comparison studies in these communities will illustrate more fully how to achieve responsible community involvement in environmental health issues.
