Lead contamination, the media and risk communication: a case study from the Ribeira Valley, Brazil

Abstract

AbstractThis paper discusses the importance of risk communication in studies of public health issues, and analyses the roles of scientists and the media in communicating scientific data, and their influence on risk perception. The findings are based on a case study from Adrianópolis in the Ribeira Valley (Brazil), conducted between 2005 and 2006, where residents were exposed to lead contamination that originated from a smelter and a sulphide mine. This study had two goals: (1) to understand the impact of information regarding lead contamination on the daily lives of the local inhabitants; (2) to understand and analyse the consequences of an absence of a strategy for risk communication by the researchers involved in the study. Besides drawing attention to the need for studies concerning passive environmental issues, the Adrianópolis case study showed that there was a lack of adequate planning for dissemination of information to local inhabitants that seriously undermined the relationships between researchers, the community and the media, and this caused damage to the various stakeholders.
