The enantiomeric ratios (ER) of α-HCH and o,p′-DDT ((+)-isomer concentration/(−)-isomer concentration) and o,p′-DDD (first eluting enantiomer/second enantiomer) were investigated in 112 human placentas from Finnish boys collected 1997–2001. Both o,p′-DDD and α-HCH showed changes in their ER depending on the total concentration of the compound in the sample. Their ERs are approaching a value close...
