A geography of moral hazard: Sources and sinks of motor-vehicle commuting externalities

Health & Place, 2014
Motor-vehicles are responsible for harms to health that are not directly experienced by individual drivers - such as air pollution and risk of injury to pedestrians. In addition to their direct effects on health, these harms also represent a moral hazard since drivers are not required to consider their effects as part of their decision to drive.

A novel methodological framework for risk zonation and source-sink response concerning heavy-metal contamination in agroecosystems.

Science of the Total Environment, 2023
The accurate identification of high-risk zones and risk source-sink responses for heavy-metal (HM) contamination of agroecosystems remains challenging due to involving multiple environmental media such as soils, dustfall, and crops and a wide range of ...
