Pregnant and lactating women are constantly and ubiquitously exposed to a wide range of environmental contaminants from a variety of sources, including air, food, water, workplace and domestic settings. Pollutants are found in human milk, according to the research, and one of the rising problems is what occurs when a nursing child is unwillingly exposed to toxins through breastfeeding. Currently, there is no solid evidence of any consistent or clinically meaningful health repercussions in newborns exposed to environmental toxins through breast milk.

The present evidence firmly suggests that the advantages of nursing exceed the possible negative effects of contaminants in human milk. The French Pediatric Society’s nutrition committee strongly supports breastfeeding, but also urges for public health initiatives to minimise general pollution in the environment, to continue encouraging breastfeeding, and to encourage research in this field.
