aMedian (range). Di-ortho PCB = CB-138, CB-153, CB-180; Mono-ortho PCB TEQ = CB-105, CB-118, CB-156, CB-167 [32]. The study group "Infections" consists of all study participants (prenatal exposure N = 190; postnatal exposure N = 175), the "White blood cells" group is a subgroup of infants among the study participants which had their WBC counts analyzed (N = 86), and within this subgroup lymphocyte subsets were analyzed in the "Lymphocyte" group composed of infants with enough blood left after WBC count analysis (N = 52). bng/g lipid. Mono-ortho PCBs: pg TEQ/g lipid [32]. Serum sampled week 32–34. cng/g fresh weight*days. Mono-ortho PCBs: pg TEQ/g fresh weight*days. Calculated as organochlorine concentration in mother's milk on a fresh weight basis*days of nursing*(%of full nursing/100). | |||
