Polybrominated Diphenyl Ethers (Pbdes)
America’s Children and the Environment, Third Edition DRAFT Indicators Biomonitoring: Polybrominated diphenyl ethers (PBDEs) EPA is preparing the third edition of America’s Children and the Environment (ACE3), following the previous editions published in December 2000 and February 2003. ACE is EPA’s compilation of children’s environmental health indicators and related information, drawing on the best national data sources available for characterizing important aspects of the relationship between environmental contaminants and children’s health. ACE includes four sections: Environments and Contaminants, Biomonitoring, Health, and Special Features. EPA has prepared draft indicator documents for ACE3 representing 23 children's environmental health topics and presenting a total of 42 proposed children's environmental health indicators. This document presents the draft text, indicator, and documentation for the PBDEs topic in the Biomonitoring section. THIS INFORMATION IS DISTRIBUTED SOLELY FOR THE PURPOSE OF PRE- DISSEMINATION PEER REVIEW UNDER APPLICABLE INFORMATION QUALITY GUIDELINES. IT HAS NOT BEEN FORMALLY DISSEMINATED BY EPA. IT DOES NOT REPRESENT AND SHOULD NOT BE CONSTRUED TO REPRESENT ANY AGENCY DETERMINATION OR POLICY. For more information on America’s Children and the Environment, please visit www.epa.gov/ace.

Certificate of Analysis
National Institute of Standards and Technology Certificate of Analysis Standard Reference Material 2257 PBDE Congeners in 2,2,4-Trimethylpentane This Standard Reference Material (SRM) is a solution of 38 polybrominated diphenyl ether (PBDE) congeners in 2,2,4-trimethylpentane. This SRM is intended primarily for use in the calibration of chromatographic instrumentation used for the determination of PBDE congeners. A unit of SRM 2257 consists of five 2 mL ampoules, each containing approximately 1.2 mL of solution. Certified Concentrations of Constituents: The certified concentration values and estimated uncertainties for the select constituents, expressed as mass fractions, are given in Table 1 along with the Chemical Abstract Service (CAS) Registry Numbers. The certified concentration values are based on results obtained from the gravimetric preparation of this solution and from the analytical results determined by using gas chromatography. A NIST certified value is a value for which NIST has the highest confidence in its accuracy in that all known or suspected sources of bias have been investigated or accounted for by NIST [1]. The measurands are the total concentrations of analytes shown on Table 1. Values are metrologically traceable to the International System of Units (SI) derived unit for mass fraction expressed as micrograms per gram. Expiration of Certification: The certification of SRM 2257 is valid, within the measurement uncertainty specified, until 31 July 2028, provided the SRM is handled and stored in accordance with the instructions given in this certificate (see “Instructions for Handling, Storage, and Use”). The certification is nullified if the SRM is damaged, contaminated, or modified. -
