| Mussel tissue - Organics
This Standard Reference Material® (SRM®) is intended for use in evaluating analytical methods for the determination of
selected polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyl (PCB) congeners, chlorinated pesticides,
polybrominated diphenyl ether (PBDE) congeners, hexabromocyclododecane (HBCD) isomers, methylmercury, inorganic
mercury, and total mercury in marine bivalve mollusk tissue and similar matrices. All of the constituents for which certified
and reference values are provided are naturally present in the freeze-dried mussel tissue. A unit of SRM2974A consists
of one bottle containing approximately 5 g of freeze-dried mussel tissue.
