Urinary concentrations of BPA and analogous bisphenols (BPF and BPS) among school children from Poland. Exposure and risk assessment in the REPRO_PL cohort

This research was funded by the National Science Centre, Poland (Grant No. 2021/41/B/NZ7/04341).The aim of this study was to determine the presence and distribution of BPA and the two main substitutes BPF and BPS in 150 urine samples of school-age children from Poland. In addition, our purpose was to assess the main socio-demographic and life-style determinants of bisphenol exposures and calculate the overall risk assessment. Samples were analyzed using high performance liquid chromatography with online sample clean-up coupled to tandem mass spectrometry (online-SPE-LC-MS/MS). Data analysis and graphics were performed using the statistical software R and ggplot2 package.The attached files contain data on BPA, BPS, BPF (in μg/L) concentrations in urine samples of children aged 7 years from the Polish Mother and Child Cohort (REPRO_PL) and socio-demographic characteristics: children’s sex, place of residence, BMI and exposure to ETS at age 7, maternal age, socio-economic status (SES), maternal and paternal educational level.Data has been encoded - ReadMe.
