Abstract

Objective To evaluate levels of urinary bisphenol A,daily intake and its influencing factors among two-year-old children. Methods Questionnaires and spot urine samples were collected from 365 children living in a county of Jiangsu province.Urinary BPA concentration was determined,daily intake was calculated and the influencing factors were identified. Results The detection rate of urinary BPA was 72.05%.The detectable range was 0.20~106.38 μg/L.The median value and the median value of BPA concentration with creatinine correction were 0.95 μg/L and 2.96 μg/g,respectively.The calculated maximum value of BPA daily intake was 4.596 μg/kg bw/24 h and was lower than the tolerable daily intake(TDI)in Europe.Statistical analysis indicated that the BPA concentrations were similar between female and male children.The locations of residence had statistically significant effects on concentrations (P<0.05). Conclusion The findings suggests that the two-year-old children are widely exposed to BPA in the studied county and the calculated daily intakes are lower than TDI in Europe.
