Some contaminants are recorded as micrograms per gram and others as nanograms per gram. Contaminant sums defined in Materials and Methods.

PCBs = polychlorinated biphenyls; DDT = dichlorodiphenyltrichloroethane; CHL = chlorpyrifos; HCB = hexachlorobenzene; HCHs = hexachlorocyclohexanes; PBDEs = polybrominated diphenyl ethers; HBCDD = hexabromocyclododecane; PBT = pentabromotoluene; HBB = hexabromobenzene; OC = organochlorine; BFR = brominated flame retardant; n.d. = levels under the limit of detection.
