Public Risk Perception of the Petrochemical Industry, Measured Using a Public Participation Geographic Information System: A Case Study of Camp de Tarragona (Spain)

Abstract

Following the implementation of the petrochemical industry, the population of Camp de Tarragona began living with a chemical risk, and after two consecutive years of chemical-related accidents with fatalities (in 2019 in the firm Carburos Metálicos, and in 2020 in the firm IQOXE), it is necessary to know the population’s perception of this activity. Therefore, this study aims to analyze the population’s risk perception regarding the petrochemical industry, by applying a Public Participation Geographic Information System (PPGIS). To this end, the risk perception data obtained from the PPGIS were correlated with the sociodemographic data from the surveys; an analysis was made of the perceived risks associated with this activity and what its possible effect would be on a territorial level, always from the point of view of the surveyed public. The results showed that the population clearly identifies on the map what the main sources of chemical risk are and which places would be affected by a possible explosion. In addition, it was verified that certain sociodemographic characteristics, such as gender or age, affect people’s perception of the risk, and that the weather conditions and anomalous situations within the industry also influence people’s perception, indicating high values of danger.
