Proximity and risk perception. Comparing risk perception 'profiles' in two petrochemical areas of Sicily (Augusta and Milazzo)

Studies on risk perception and 'proximity' usually compare populations living close to or far away from alleged pollution sources. Taking a different perspective, this paper compares the risk perception profiles of populations residing in the neighborhood of two petrochemical sites in Sicily (Italy), in order to check for similarities and differences. Based on the results of a survey carried out in the period 2008-2009 (1222 interviews), risk perception is investigated; finding that on a list of 15 social risks, the two populations show a similar risk perception only as far as hazards that can be retraced to the territorial industrial environment are concerned, while other risks are differently perceived. Specific risk perception indicators are presented and the relationship between risk perception, socioeconomic characteristics, and health is also deepened. The conclusion of this study is that proximity to industrial pollution sources influences risk perception and assimilates risk perception profiles of populations.
