A Spanish study found traces of environmental pollution in breast milk BreastMilk Pediatrics Breastfeeding ChildHealth env_int_journal
By Dr. Liji Thomas, MDJul 6 2022Reviewed by Benedette Cuffari, M.Sc. Breastfeeding is important for the health of both the mother and infant. By providing nutrients, immunologic factors, emotional satisfaction, and bonding, breastfeeding is recommended to begin within an hour of birth and continue for a minimum of six months.
Children who were breastfed as infants are more likely to be protected against excess weight gain in later life, have a higher intelligence quotient and have greater capabilities to think and react to stimuli. Pollution and breastmilk The cumulative exposure of women to environmental pollutants, especially persistent organic pollutants such as polychlorinated biphenyls , dioxins, and furans, as well as toxic metals, has led these chemicals to be identified at varying concentrations within breastmilk. Some of these chemicals disrupt normal endocrine function, which could subsequently affect the normal development of the infant.
Nine of 11 PCB congeners were detected in the samples, with the highest concentration being about 800 pg/mL for PCB-153 Chlorpyrifos, for example, was present in up to 40% of samples at concentrations of up to 150 pg/mL and 11 ng/g fat. While these levels compare with those of most other non-European countries, as European levels were not available at the time the study was conducted, they were much lower than those reported in Iran or India, which were over 2,000 pg/mL and about 70 ng/g fat.
Notably, infant formula also contains environmental pollutants, as does baby food, presumably from the manufacturing chain.
