摘要:The reduction of disaster risks is gaining relevance in the environmental sciences, resulting in very relevant territorial diagnoses. Having that in mind, the goal of the present work is to analyze and evaluate the levels of technological threats arising from the storage of dangerous products in the city of Paranaguá. The developed methodology has been theoretically based in the Spanish legislation “Reglamento de Actividades Molestas, Insalubres, Nocivas y Peligrosas, 1961” (Regulation of Irritating, Unhealthy, Noxious and Dangerous Activities, 1961), as well as complemented with a proposal from the Organization of the United Nations (UN) and from the National Agency of Land Transports of Brazil (ANTT). The analysis was performed with the help of the ArcGIS 10.1 software, considering distance as an exposure factor. From the application of this methodology, it can be inferred that 84.75 km² are under technological threat, and more than 124,000 people would be affected in case an event takes place.
