    Metadata Updated: September 30, 2025

    SRM 1953 Organic Contaminants in Non-Fortified Human Milk - This Standard Reference Material (SRM) is intended for use in evaluating analytical methods for the determination of selected polychlorinated biphenyl (PCB) congeners, chlorinated pesticides, polybrominated diphenyl ether (PBDE) congeners, and elements in human milk and similar matrices. Reference concentration values are provided for polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), as well as some inorganic constituents. An information concentration value is provided for the PCB mixture Aroclor 1260. All of the constituents for which certified, reference, and information concentration values are provided in SRM 1953 are naturally present in the milk. A unit of SRM 1953 consists of five bottles of approximately 5 mL of frozen non-fortified human milk. This data is public in the Certificate of Analysis for this material.
