GUILLEN-MENDOZA, Daniel et al. Determination of lead levels in breast milk of breastfeeding mothers in nine districts in Lima, Peru. Acta méd. Peru [online]. 2017, vol.34, n.2, pp.90-94. ISSN 1728-5917.

Objective: To determine lead levels in breast milk in primiparous women from nine districts in Lima. Materials and methods: We conducted a cross-sectional study between October 2010 and August 2012. One-hundred samples of breast milk were included, these were from women who lived for more than 5 years in the same area in Lima. We used the atomic absorption spectrophotometry method for the measurements. Result: Thirty-seven percent of the samples had detectable lead levels, six of them were between 5.0 and 9.9 ng/g and five were over 10 ng/g. We did not identify associated risk factors. Conclusion: An important percentage of samples of breast milk are contaminated with lead, particularly in persons living in northern Lima
