Workshop on Modeling Air Toxics with HYSPLIT

Estimated 1999 mercury emissions from large point sources in Mexico, based on an inventory prepared by Acosta and Associates for the Commission for Environmental Cooperation.
Mark Cohen gave a one-day course August 24, 2009 on modeling air toxics with HYSPLIT to a group of Mexican government and academic scientists in Mexico City. The course was part of a week-long workshop organized by the Commission for Environmental Cooperation (CEC).
The course utilized the extensive training materials developed for HYSPLIT by Roland Draxler, Glenn Rolph and others at ARL, and also included new materials regarding simulation of mercury and dioxin. Several hand’s-on computer modeling exercises were included in the training. More information, including workshop data and materials, is available regarding this 2009 Mexico Air Toxics Training.
Review of Great Lakes Air Toxics

Estimated mean air transport travel times for atmospheric pollutants to the Great Lakes, prepared by Eva Voldner for the International Joint Commission.
A five-part set of review documents regarding the emissions, monitoring, fate and transport of toxic air pollutants in relation to the Great Lakes was prepared for the International Joint Commission (IJC) in 1997. The review focused on the 27 Level I and Level II pollutants identified in the Binational Virtual Elimination Strategy.
