Background: Human exposure to phthalates, endocrine disruptors ad reproductive toxicants, is ubiquitous because of their extensive use as plasticizers. Breast milk is the optimal source of nutrition for newborns, however, it can be a source of exposure to several environmental contaminants, Including phthalates. Up to date limited information exists on lactational exposure to phthalates and their metabolites in Italy: the aim of this study, therefore, was to determine the levels of 8 different phthalates diesters and monoesters in breast milk of women living in Modena, Italy, and to investigate the relationship with women's diet and other habits.Methods: 130 women (mean age: 33; range: 19 - 45 years) provided a sample of breast milk (30-40 days postpartum) and filled in a questionnaire on personal data and on potential sources exposure to phthalates. After solid extraction, samples were analysed by triple Quad LC/MS Mass Spectrometry.Results: Phthalate diesters, due to their metabolic degradation, resulted almost undetectable. Phthalate monoesters appeared more widespread. Among them, mono-isononylphthalate (MiNP) was detected in 125 breast samples (mean: 1.63 +2.71; range: 0.10 - 18.4 µg/l) and mono-ethylphthalate (MEP) in 106 samples (mean: 2.35 + 7.36; range: 0.04 - 69.0 µg/l). Their levels appeared higher in lactating women more frequently using cosmetics or consuming food and beverages preserved in plastic containers. Differences, however, were not statistically significant. Further, levels appeared well below the daily intake levels established by the European Food Safety Authority (EFSA).Conclusions: Although a number of phthalate monoesters were detected in maternal breast milk, their concentrations tended to be lower than those reported in other international studies and the values recommend by EFSA. Human milk represent a unique nourishment for infants in a crucial period of their life: its use should not be discouraged.
