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 purpose of this protocol is to provide guidelines for the analysis of carpet dust samples for arsenic (As). This method involves the extraction of the analyte from carpet dust samples using 50% ultra-pure nitric acid, and subsequent analysis by hydride generation atomic fluorescence spectrometry (HGAFS). The analyte is identified by the presence of fluorescence at its specific wavelength. Quantitation of the analyte is carried out using a standard calibration curve. Recovery of the analyte is monitored using samples that are spiked with standards prior to the extraction process. Keywords: carpet dust; arsenic.
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 Region 5 study was conducted in EPA's Region 5 (Ohio, Michigan, Illinois, Indiana, Wisconsin, and Minnesota), and included personal exposure, residential concentration, and biomarker measurements of metals and VOCs. The study was conducted by the Research Triangle Institute (RTI) and the Environmental and Occupational Health Sciences Institute (EOHSI). The scope and design of the study are detailed in the following article: E. Pellizzari et al., Population-Based Exposure Measurements in EPA Region 5: A Phase I Field Study in Support of the National Human Exposure Assessment Survey. Journal of Exposure Analysis and Environmental Epidemiology, Vol. 5, No. 3, 1995, pp. 327-358.
