Characteristics of environmental harm in the context of air pollution

摘要

A framework that allows a simple qualitative assessment of both technical and socio-economic aspects of environmental harm has been developed; that is a framework that captures not only the physical aspects of damage but also how society may feel about it. Technical characteristics of harm include spatial and temporal extent, severity, irreversibility and uniqueness. Social aspects include dread, distrust, equity and imposition. By plotting these on separate axes of a graph it is possible to assess those attributes of greatest concern, draw conclusions as to the nature of the harm, and public perception of it, as well as gaining some insight into appropriate courses of action. The results of applying the methodology to a radioactive release are presented and placed in the context of a range of other air pollution hazards.
