This is due to the tendency for bioaccumulation in lipids, which breast tissue and organs tend to have a high percentage of. I'm not an expert, just what I remember reading, so someone please chime in for the exact mechanisms. Likely to be some other contributing factors, like their role in producing breast milk biochemistry related to that (speculating: accumulates in the mother but doesn't get passed on to the child).
