Article Synopsis
- The study examined the presence of aluminum (Al), antimony (Sb), and lithium (Li) in pooled breast milk samples from 83 donor mothers in Spain.
- Concentrations of Al were found in 94% of samples, while Sb and Li were present in 72% and 79%, respectively, with Al having the highest median concentration.
- The research highlighted that the levels of these metals were mainly linked to the mothers' dietary habits and the lipid content of breast milk, along with the use of personal care products, rather than the postpartum timing.
Background: Human breast milk is considered the optimal source of nutrition for infants. Milk from breast milk banks offers an alternative to infant formulas for vulnerable hospitalized neonates most likely to benefit from exclusive human milk feeding. However, breast milk can also be a source of exposure to environmental contaminants, including endocrine-disrupting chemicals (EDCs).

Methods: Pb, Hg, Cd, and As concentrations were measured in 242 pooled breast milk samples from 83 donors to a Human Milk Bank in Spain, in 2015-2018, determining their association with the donors' sociodemographic profile, dietary and lifestyle habits, and post-partum time, among other factors, and with the nutritional characteristics of samples. Mixed-effect linear regression was used to identify predictors of Hg and As concentrations in breast milk and mixed-effect logistic regression to identify predictors of the presence of Pb and Cd.
Article Synopsis
- Breast milk, while providing optimal nutrition for infants, can also expose them to environmental contaminants like PFAS (perfluoroalkyl compounds) due to their widespread presence in the environment.
- A study analyzed pooled milk samples from 82 donors, finding PFAS present in nearly all samples, with varying concentrations and types, indicating a potential health concern.
- Factors influencing PFAS levels in breast milk included dietary habits, particularly the consumption of animal products and the use of personal care products like skin care and makeup.
Introduction: the pandemic caused by SARS-CoV-2 led to the declaration of the state of sanitary alarm between March and June 2020 in Spain. The activity of human milk banks was affected during that period, making it necessary to implement new measures in order to promote milk donation and diminish said impact. Method and objective: the aim of the study was to evaluate the impact of the state of alarm decreed from March 14 to June 22, 2020 on the breastmilk bank at Hospital Virgen de las Nieves, Granada, Spain, in comparison with the same period during the previous year.
