Determinants of risk perceptions of a hazardous waste site.

Toxic chemicals from waste sites are viewed as a major cause of multiple health problems, especially cancers. Accurate health risk estimates moderate fears and are linked to levels of education.

Journal Article

A before stimulus after quasi experiemental design is used to assess the factors relating to risk perceptions of a hazardous waste site. First, a pretest obtains measures of attitudes and beliefs about hazardous waste and waste sites. Second, a detailed hypothetical "superfund" scenario, including a complex cleanup plan is introduced. Finally, indices of health risk estimates, trust, knowledge, and other pertinent beliefs are obtained. Levels of concern, both before and after cleanup, are the dependent variables. Independent variables include risk management options, health risk estimates, trust and five sociodemographic characteristics. Concern is extremely high prior to cleanup and moderately high after cleanup. Concern is a clear function of health risk estimates. Toxic chemicals from waste sites are viewed as a major cause of multiple health problems, especially cancers. Accurate health risk estimates moderate fears and are linked to levels of education. Education, however, does not explain concern. Trust is a major factor explaining concern and health risk estimates. The implications of these findings for risk communication is discussed.
