Integrated Atmospheric Deposition Network (IADN)

The IADN was created in response to the Clean Air Act Amendments and   Great Lakes Water Quality Agreement (Annex 15) in 199  by the   recommendation of the International Joint Commission. The intent of   the network is to measure and evaluate pollution concentrations in   the atmosphere (airborne vapor, airborne particles, and   precipitation) at a regional level of detail. In addition, loadings   of these selected toxic organic contaminants to the Great Lakes and   their virtual elimination dates from the atmosphere are calculated.   We also are exploring the relative importance of short vs. long-  range transport to the atmospheric concentrations and agricultural   inputs of in-use pesticides. Organic toxics of interest are   chlorinated pesticides, polychlorinated biphenyls (PCBs), and   polycyclic aromatic hydrocarbons (PAH). Recently, polybrominated   diphenyl ether (PBDE) flame retardants are included as regular   analytes.    Samples have been collected continuously at five master sites and at   several satellite sites by both the U.S. and Canadian investigators.   There are five master stations (one on each lake) and several   satellite stations. The United States (specifically Indiana   University) is responsible for the master stations on Lakes   Superior, Michigan, and Erie. Indiana University is also responsible   for the two satellite stations, which are located at Cleveland on   Lake Erie and in downtown Chicago near Lake Michigan. The satellite   site Brule River on Lake Superior was operated from 1994 to 2  2.     For inter-comparison with the data obtained by the Canadians,   Indiana University also measures samples acquired at Point Petre on   Lake Ontario.      (polychlorinated biphenyls); (polychlorinated biphenyl); (PCBs);   (PCB); (PCBs); (polycyclic aromatic hydrocarbons); (polycyclic   aromatic hydrocarbon); (PAHs); (PAH's); (PAH); (polybrominated   diphenyl ether); (PBDE's); (PBDEs); (PBDE); (flame retardants);   (flame retardant); (toxic organic); (toxic organics); (POP's);   (POPs); (POP); (persistent organic pollutant); (persistent organic   pollutants); (pesticide); (pesticides); (human health)
