Introduction: The aim of this study is to provide data on the evaluation of tungsten in breast milk. Materials and Methods: In this study, a cross-sectional survey design was used to evaluate a community of 950 inhabitants where lactation is practiced by 100% of mothers, with an average time of 12.7 months. It was carried out with the participation of women breastfeeding at that time in the community, 17 census sample, ages between 17 and 49 years, accepted to participate 14 (82%), in the month of June 2017. The analysis was carried out with the inductively coupled plasma mass spectrometry (ICP-MS) model 7900 brand Agilent Technologies. Results: Tungsten or tungsten was found in 100% of the samples of breast milk studied, it was determined minimum 0.026, maximum of 1.746, median 0.0785, DS 0.452, coefficient of variation 1.940. 1μg / L. This unusual finding of Tungsten poses new challenges on environmental pollution and its possible effects on maternal child health, especially in the prenatal stage. Discussion: This study shows in all the mothers studied with which they feed their children milk, they have Tungsten levels. The possible effect on the health of Tungsten absorbed at low doses during lactation is not known. Tungsten should be studied through longitudinal studies of exposure.
