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.

Description:

The Metals in Dust data set contains analytical results for measurements of up to 11 metals in 182 dust samples over 91 households. Samples were taken by collecting dust samples from the indoor floor areas in the main room and in the bedroom of the primary resident. In addition, surface wipes were collected within the home. The primary metals of interest include lead (CAS# 7439-92-1), arsenic (CAS# 7440-38-2), cadmium (CAS# 7440-43-9), nickel (CAS# 7440-02-0), chromium (CAS# 7440-47-3), barium (CAS# 7440-39-3), manganese (CAS# 7439-96-5), selenium (CAS# 7782-49-2), vanadium (CAS# 7440-62-2), copper (CAS# 7440-50-8), and zinc (CAS# 7440-66-6). Keywords: dust; metals.

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.
