- Phthalates and bisphenol A (BPA) are plasticizers used in many industrial products that can act as endocrine disruptors and lead to metabolic diseases. During the LIFE PERSUADED project, we measured the urinary concentrations of BPA and Di(2-ethylhexyl)phthalate (DEHP) metabolites in 900 Italian women representative of the Italian female adult population (living in the north, centre, and south of Italy in both rural and urban areas). The whole cohort was exposed to DEHP and BPA with measurable levels above limit of detection in more than 99% and 95% of the samples, respectively. The exposure patterns differed for the two chemicals in the three macro-areas with the highest urinary levels for DEHP in south compared to central and northern Italy and for BPA in northern compared to central and southern Italy. BPA levels were higher in women living in urban areas, whereas no difference between areas was observed for DEHP. The estimated daily intake of BPA was 0.11 μg/kg per day, about 36-fold below the current temporary tolerable daily intake of 4 μg/kg per day established by the EFSA in 2015. The analysis of cumulative exposure showed a positive correlation between DEHP and BPA. Further, the reduction of exposure to DEHP and BPA, through specific legislative measures, is necessary to limit the harmfulness of these substances.

- <b><i>Background/Aims:</i></b> Polybrominated diphenyl ethers (PBDEs) are widely used as flame retardants and have shown endocrine disruption properties in experimental studies. The aim of this study was to investigate the association between the exposure to PBDEs and alterations of puberty in girls referred for idiopathic central precocious puberty (ICPP) and premature thelarche (PT). <b><i>Methods:</i></b> A case-control study was conducted in 124 girls: 37 girls with ICPP (mean age 7.4 ± 0.9 years), 56 with PT (mean age 5.7 ± 2.1 years) and 31 controls (mean age 5.4 ± 1.9 years). PBDE serum concentrations, hormone levels and anthropometry were assessed. PBDE concentrations were corrected for total serum lipid content. Individual exposure to PBDEs was evaluated through ad hoc questionnaires. <b><i>Results:</i></b> PBDE serum concentrations corrected for total lipid content were significantly higher in girls with PT (mean 1.49 ± 0.63 log ng/g) than in controls (mean 1.23 ± 0.54 log ng/g; p < 0.05). PT girls showed higher levels of PBDE than ICPP girls (1.49 ± 0.63 vs. 1.37 ± 0.49 log ng/g), though this was not significant. An analysis of the questionnaires revealed no significant differences in exposure between the three groups. <b><i>Conclusion: </i></b>Our findings suggest that higher concentrations of serum PBDEs are associated with PT in girls.

Italian Children Exposure to Bisphenol A: Biomonitoring Data from the LIFE PERSUADED Project

Tidskriftsartikel (refereegranskat)abstract
- A human biomonitoring (HBM) study on bisphenol A (BPA) in Italian children and adolescents was performed within the LIFE PERSUADED project, considering the residing areas, sex and age. The median urinary BPA level was 7.02 µg/L, with children living in the South of Italy or in urban areas having higher levels than those residing in the North or in rural areas. Children aged 4–6 years had higher BPA levels than those aged 7–10 and 11–14 years, but no differences were detected between sexes. The exposure in Italian children was higher compared to children from other countries, but lower than the HBM guidance value (135 µg/L). The estimated daily intake was 0.17 μg/kg body weight (bw) per day, about 24-fold below the temporary Tolerable Daily Intake of 4 μg/kg bw per day established by the European Food Safety Authority. However, this threshold was exceeded in 1.44% of the enrolled children, raising concern about the overall exposure of Italian young population.
