..These pilot data suggest that nursing mothers are exposed to phenols and parabens; urine is the best measurement matrix; and correlations between chemical and endogenous immune-related biomarkers merit further investigation. ..
Calafat A, Valentin Blasini L, Ye X. Trends in Exposure to Chemicals in Personal Care and Consumer Products. Curr Environ Health Rep. 2015;2:348-55 pubmed publisher
..We compare US trends to national trends from Canada and Germany. Exposure to the original compounds is still prevalent among these general populations, but exposures to alternative chemicals may be increasing. ..

..Nevertheless, to demonstrate the utility of these measures for exposure and risk assessment purposes, additional data about sampling and storage of the milk, and on the stability of the analytes in milk, are needed. ..
