Human milk is an important part of the diet for infants up to six months of age. Scientists know relatively little about the amount of some chemicals in human milk.  The purpose of this research was to measure phthalates and di-(2-ethylhexyl) adipate (DEHA) in human milk. Phthalates are chemicals widely used in plastics and personal care products.  DEHA is also used in products containing plastic such as plastic wrap.

Researchers at Health Canada developed a laboratory method to measure DEHA and phthalates in 305 human milk samples collected from the Canadian Maternal-Infant Research on Environmental Chemicals Study. Some phthalates were not detected in any of the samples while DEHA and certain other phthalates were detected at low concentrations

This research demonstrated the feasibility of measuring these chemicals in human milk and concluded that concentrations of all phthalates and DEHA in human milk are relatively low.
