Molecular markers are groups of compounds that come from specific sources. Following the dispersion and reactions of these compounds in the environment can frequently help us understand biotic and abiotic geochemical processes. This talk will focus on collections of anthropogenic compounds as they move through the earth`s atmosphere. We will present two examples: (a) We have used the concentrations of mixtures of twenty-two highly chlorinated pesticides in tree bark to understand the global dispersion of these compounds and to distinguish the {open_quotes}global distillation effect{close_quotes} from local sources.
