THE RISK MANAGEMENT FOR INDOOR AIR POLLUTION CAUSED BY FORMALDEHYDE IN HOUSING: THE HISTORICAL PERSPECTIVES ON EARLY WARNINGS AND ACTIONS

摘要

When addressing a broad range of hazards due to environmental pollutants linked to public health or the environment, there were some cases that the regulatory actions were delayed due to scientific uncertainty,ambiguity or complexity of causes inherent in the consequences of risk assessment regardless of early warnings on hazards. As the result, the hazards were expanded in these cases. Indoor air pollution caused by formaldehyde in housing have been conducted many investigations or regulatory actions in Europe and North America. We implemented the case studies of historical perspectives on early warnings and actions concerning health hazard due to formaldehyde in Germany, USA, Canada and Japan. We showed the ranges of actions that may be taken in response to risk from indoor air pollutants, which would be one of the risk management model for indoor air pollution.
