Identifying Potential Impact of Lead Contamination Using a Geographic Information System
/ The main objective of this research was to identify the potential hazards associated with lead contami-nation from fixed sources in the city of Tijuana. An exploratory model is presented that describes the potential polluting sources as well as the exposed universe. The results of the analysis provide a clear picture of the geographic distribution of hazards areas for potential lead pollution in Tijuana. The findings are indicative of the dramatic consequences of rapid industrialization and urbanization in a city where there have not been significant planning efforts to mitigate the negative effects of this growth. The approach followed helps to narrow the universe of potential pollution sources, which can help to direct attention, research priorities, and resources to the most critical areas.KEY WORDS: Lead contamination; Industrial hazards; GIS; Tijuana; Mexico
