San Antonio la Isla in Mexico reflects the flat Estado de México Toluca Valley corridor position at 2,580 metres, with vehicle traffic on surrounding roads and the agricultural and rural residential character contributing modest local sources. The elevated Toluca Valley's topographic enclosure creates modest concentration under inversions, while the altitude worsens ozone formation and the Mexico City-Toluca metropolitan regional background influences the area throughout most of the year.
