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:

This document lists available protocols and SOPs for the NHEXAS Phase I Maryland study. It identifies protocols and SOPs for the following study components: (1) Sample collection and field operations, (2) Sample analysis and general laboratory procedures, (3) Data Analysis Procedures, and (4) Quality Assurance. Keywords: protocols; standard operating procedures (SOPs).

The National Human Exposure Assessment Survey (NHEXAS) is a federal interagency research effort coordinated by the Environmental Protection Agency (EPA), Office of Research and Development (ORD). Phase I consists of demonstration/scoping studies using probability-based sampling designs. The studies collected household environmental and personal samples for chemical analysis, and questionnaires were administered. The NHEXAS Phase I Questionnaires were organized into six modules for simplicity in administration (to minimize respondent burden and maximize participation rates at each step) and for collecting information that can be temporally related to the exposure, concentration, and/or biological measurements collected in NHEXAS: Descriptive, Baseline, Technician, Follow-up, Time and activity diary, and Dietary diary (and follow-up). The NHEXAS-Maryland study sampled residences determined by a proportion-based sample of Baltimore and four adjacent counties and measured metals, pesticides, and polynuclear aromatic hydrocarbons (PAHs). The study was conducted by Harvard University, Emory University, Johns Hopkins University, and Westat. Data collection occurred up to six times over one year for the participating households. Analytical results were obtained under strict QA/QC requirements during collection, processing, and final deposition into databases.

NOTE: The U.S. Environmental Protection Agency (EPA), through its Office of Research and Development (ORD), partially funded and collaborated in the research described here. This SOP is part of the Quality Systems Implementation Plan (QSIP) that was reviewed by the EPA and approved for use in the Maryland study and is provided for documentation purposes. It does not reflect EPA methods and should not be construed as such. The methods were generated by the consortium to be used for the NHEXAS pilot study.
