WARNING! DATA USE RESTRICTIONS
Read Carefully Before Using
The EPA does all it can to ensure that the identity of survey participants cannot be disclosed. All direct identifiers, as well as any characteristics that might lead to identifications, are omitted from the data. Any intentional identification or disclosure of a person or establishment violates the assurances of confidentiality given to the providers of the information. Therefore, users will (1) use the data in this study for statistical reporting and analysis only; (2) make no use of the identity of any person or establishment discovered inadvertently and will advise the HEDS Administrator of any such discovery; (3) will not link this data with individually identifiable data from other EPA or non-EPA data.
By using the data you signify your agreement to comply with the above-stated statutorily based requirements.
Arizona Border Study Consortium. U.S.-MEXICO BORDER PROGRAM ARIZONA BORDER STUDY--STANDARD OPERATING PROCEDURE FOR OPERATION, CALIBRATION, AND MAINTENANCE OF THE PERKIN-ELMER 5100 PC ATOMIC ABSORPTION SPECTROMETER (BCO-L-5.1). U.S. Environmental Protection Agency, Washington, D.C.
The purpose of this SOP is to outline the start-up, calibration, operation, and maintenance procedures for the Perkin-Elmer 5100 PC Atomic Absorption Spectrophotometer (PE 5100). These procedures are used for the determination of the target trace metal, as in soil, house dust, filter, and surface and dermal wipe sample digestates. This procedure was followed to ensure consistent data retrieval during the Arizona NHEXAS project and the Border study. Keywords: laboratory; atomic absorption spectrophotometry; metals; AAS.
The U.S.-Mexico Border Program is sponsored by the Environmental Health Workgroup of the Border 2012 Program. The Environmental Health Workgroup's mission is "to identify and address, in a binational framework, environmental factors that pose the highest risk to human health so that exposure to such factors may be reduced." To accomplish this mission, studies are performed to help understand the interrelationships between environmental conditions and human health. The Arizona Border Study, sponsored by the Environmental Health Workgroup, is an extension of the Arizona National Human Exposure Assessment Survey (NHEXAS) Phase I Study. The Arizona Border Study collected household environmental and personal samples for chemical analysis, and questionnaires were administered. The NHEXAS Phase I Questionnaires were used with some adjustments and were organized into seven modules (Descriptive, Baseline, Technician, Follow-up, Time and activity diary, Dietary diary, and Supplement) for simplicity in administration. The questionnaires are designed for collecting information that can be temporally related to the exposure, concentration, and/or biological measurements. The Arizona Border study sampled residences determined by a population-based probability research design for populations in the Arizona counties bordering Mexico, and measured metals, pesticides, polynuclear aromatic hydrocarbons (PAHs), and volatile organic compounds (VOCs). Analytical results were obtained under strict QA/QC requirements during collection, processing, and final deposition into databases. In addition, strict standard operating procedures were followed throughout the Arizona Border study. The study was conducted by a consortium composed of the University of Arizona, Battelle Columbus, and the Illinois Institute of Technology. Data collection occurred between September 1997 and July 1998 for the participating households.
