RT Journal A1 Zobel LR, Olsen GW, Butenhoff JL T1 PErfluorinated compounds and immunotoxicity in children JF JAMA JO JAMA YR 2012 FD May 9 VO 307 IS 18 SP 1910 OP 1911 DO 10.1001/jama.2012.3599 UL http://dx.doi.org/10.1001/jama.2012.3599 AB A Danish study examined whether perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) may impair children's immune systems.2 Fei et al2 randomly selected 1400 pregnant women from 91 827 persons in the Danish National Birth Cohort between 1996 and 2002 and investigated their offspring's history of hospitalizations for infectious diseases through 2008 (n = 363 children). Prenatal serum concentrations of PFOS and PFOA, similar to the values in the study by Grandjean et al,1 were not associated with hospitalizations for infectious diseases. Fei et al2 concluded that their data did not support the hypothesis that prenatal PFOS and PFOA exposures decrease resistance to childhood infections.
