Organic contaminants in non-fortified human serum
This material is intended for use in evaluating analytical methods for the determination of selected
polychlorinated biphenyl (PCB) congeners, chlorinated pesticides, and polybrominated diphenyl ether (PBDE)
congeners in human serum and similar matrices. A unit of NIST-1957 consists of five bottles of freeze-dried nonfortified
human serum which 首ld be reconstituted with 10.7 mL of water. Certified values are given for eight
PCB congeners (some in combination), three chlorinated pesticides, and four PBDE congeners along with one
polybrominated
biphenyl congener. In addition, reference values are provided for 23 other PCB Congeners, chlorinated
pesticides and PBDE congeners, for seven perflourinated compounds (PFCs), for eleven polychlorinated
dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). Information values are provided for two
hydroxylated compounds and for Aroclor 1260. All of the constituents for which certified and reference values are
provided in SRM 1957 are naturally present in the serum.
