Technological Solutions and Contested Interpretations of Scientific Results: Risk Assessment of Diesel Emissions in the United States and in West Germany, 1977-1995.

This article traces the different classifications of diesel emissions either as "safe" or as "hazardous" in the US and in West Germany between 1977 and 1995. It argues that the environmental regulation of diesel emissions was a political threshold. It contributes to our general understanding of how politicians, environmental lobbyists, scientists, and engineers constructed the standards and norms that defined the "safe" limit of environmental pollutants.
