Spatial approximation of gas concentrations resulting from mobile sources in Panama City, using geographic information systems
Air pollution is the accumulation in the air of concentrations of various substances that can cause damage to ecosystems. It is not only a consequence of industrialization in or near urban centers, but also it is necessary to consider factors such as vehicle fleet size and poor road infrastructure....

| Summary: | Air pollution is the accumulation in the air of concentrations of various substances that can cause damage to ecosystems. It is not only a consequence of industrialization in or near urban centers, but also it is necessary to consider factors such as vehicle fleet size and poor road infrastructure. In Panama, the concern for air pollution comes from the 90s, with the approval of the law No. 36 of 1996 that established the Specialized Analysis Institute (IEA in Spanish) at the University of Panama (UP). This institute has the responsibility to install and maintain a network of stations to measure and analyze air pollution parameters at a national level, specially those produced by internal combustion engines. Panama is considered as the Central American city with the highest air pollution index, due to the impact produced by emissions from the transport sector (Swisscontact 1999). In this article, we analyzed the relationship between population density vs ozone, by employing Geographic Information System (GIS) over monthly averaged data en μg/m3, for 2005, 2008 and 2010. Influence zones of each one of the four monitoring station evaluated were also used. Finally, it was found that highest ozone concentrations were found in areas with highest population density. |
