EPA (2000) identifies one study that found changes in the distribution of alanine aminotransferase and aspartate aminotransferase concentrations in breastfed infants.

Independent of changes over time in the DLC content of food and in dietary intake, it is generally recognized that body burdens of DLCs increase with age due to the long half-lives of these compounds. There is evidence of decreasing concentrations of DLCs in human breast milk: — There has been an approximately 25 percent decrease in I-TEQDF in cow and human milk fat between 1990 and 1994 in Germany. — In Birmingham, England, breast-milk concentrations were 37 pg ITEQDF/g of fat in 1987 to 1988 and 18 pg I-TEQDF/g of fat in 1993 to 1994, while concentrations at similar times in Glasgow, Scotland, were 29 pg I-TEQDF/g of fat and 15 pg I-TEQDF/g of fat, respectively.
