‘Total’ concentrations refer to the sum of the free plus conjugated species. Raw data only from participants with milk samples available; A and B subscripts denote two aliquots from the same sample (MilkA and MilkB). A portion of MilkA was used in previous analyses for other environmental chemicals (vonEhrenstein et al 2010). M:S:U Ratio calculated using MilkB aliquots (tubes not opened prior to analyses) and Serum ‘Total’ values.
N/A=not applicable; limit of detection (LOD).
