title: Bisphenol A and nonylphenol in foodstuffs: Chinese dietary exposure from the 2007 total diet study and infant health risk from formulas.
abstract: Concentrations of bisphenol A (BPA) and nonylphenol (NP) were measured in food samples from the 2007 Chinese total diet study (TDS). BPA and NP were detected in 72 and 143 of 144 TDS samples, respectively, with concentrations ranging from 20 ng/kg to 267 μg/kg and 30 ng/kg to 1,268 μg/kg, respectively. BPA was highest in Hebei (HB) province for most food groups. NP was much higher in milk than in other foods across all the provinces. Mean exposures to BPA and NP were estimated to be 43 ng/kg bw/day and 520 ng/kg bw/day for a Chinese adult, respectively, well below the tolerable daily intake (TDI). Mean exposure to NP from formula for infants aged 0-6 years ranged from 300 ng/kg bw/day to 17 μg/kg bw/day. For infants aged 0-1 year, intakes ranged from 5 to 17 μg/kg bw/day, which is above the TDI.
