atmospheric deposition of toxic materials
Abstract:The Integrated Atmospheric Deposition Network is a joint effort of the United States and Canada to measure atmospheric deposition of toxic materials to the Great Lakes. It was mandated by Annex 15 (Airborne Toxic Substances) of the Great Lakes Water Quality Agreement (GLWQA) between the United States and Canada. The GLWQA was originally signed in 1972, and amended in 1978 and again in 1987, when Annex 15 was added among others. The network also fulfills the requirements of section 112 (m) of the U.S. Clean Air Act Amendments (CAAA) of 1990, the Great Waters Program, which calls for a Great Lakes atmospheric deposition network. The plan for development of the new network was approved in 1990 (Canada/U.S. Coordinating Committee on Annex 15, 1990). Measurements of the following toxic chemicals were to begin during Phase I (1991 and 1992): total polychlorinated biphenyls (PCBs) and major congeners, the alpha and gamma isomers of hexachlorocyclohexane (HCH), polyaromatic hydrocarbons (PAHs) with B(a)P as the goal, and lead (Pb). Those toxic compounds included as a second priority, and known to need considerable methods development, included chlorinated pesticides such as DDT and its metabolites, as well as chlordane, nonachlor, heptachlorepoxide, methoxychlor, dieldrin, HCB, and endrin. Also in the second-priority group were the trace metals arsenic, selenium, cadmium, and mercury. The plan called for installation of one master (research-grade) sampling station on each of the Great Lakes by the end of 1992, but this schedule was advanced by one year to meet the requirements of the Great Waters Program in the 1990 CAAA, which required one sampling site on each lake by the end of 1991. The plan also calls for two or more satellite (routine) sites on each of the Great Lakes, plus one or more background stations. Plans for installation of satellite sites have not yet been implemented. The master stations operate two or more of the primary network samplers to provide the sampling replication necessary to determine sampling and analytical precision. They typically provide enough space and electric power to accommodate additional research. The satellite stations are expected to include single samplers of the same types used at the master stations. All sampling and analytical operations are governed by the Quality Assurance Project Plan (QAPjP) for the work (Gatz et al., 1993). Details of analytical methods are given by Willett and Basu (1993) and are summarized below.
