Zapotlanejo's air quality reflects the flat Jalisco Altos plateau at 1,580 metres adjacent to Guadalajara, with vehicle traffic on surrounding roads and the leather goods, livestock, and agricultural corridor contributing elevated chemical PM2.5 from the tanning operations. The elevated plateau position aids dispersal on most days, while the leather tanning's distinctive chemical emissions represent Zapotlanejo's most locally unique air quality contribution throughout most of the year.
