AB: Observations of highly elevated concentrations of cyanides in the atmosphere above Mexico City during March 2006, demonstrate that biomass burning significantly impacts the regional air quality. In particular, such fires significantly enhance the amount of benzene, carbon monoxide, and organic aerosol in the outflow from the basin. The biomass burning emissions coupled with the anthropogenic NOx , fuel ozone production in the outflow. Significant improvements in visibility may be realized with burning management in and around the basin.
