The human exposures can come from various routes, since many products nowadays contain BPA. It was also reported that BPA existed in atmospheric environment all over the world, especially in South Asia where the concentrations are relatively high. Besides, indoor air and indoor dusts are also suspected to be the sources of exposures for BPA. Based on published literatures, the contributions of BPA to human exposures mainly came from dietary sources. However, the levels in indoor air and indoor dusts are more important for infants and toddlers, due to their unique life styles. To assess the exposures for this susceptible group, there is a must to determine the associated concentrations, since no data is currently available in Taiwan. This is a three years joint-project, which will focus on the developing of sampling and analytical methods for BPA in indoor air, indoor dusts as well as in atmospheric environment. Besides, the distributions of BPA in different environmental matrix will also be determined. The purposes of this research are: (1) to develop the sampling and analytical method for BPA in indoor air by SPME (solid phase microextraction) with non-equilibrium sampling through the analysis by triple quadrupole gas chromatography with tandem mass spectrometry (GC/MS/MS) (8/2013~7/2014); (2) to develop the analytical method for BPA in indoor dusts by SPME with MAE (microwave assisted extraction) through the analysis by GC/MS/MS (8/2013~7/2014); (3) to develop the sampling and analytical method for both gaseous and particle bound BPA in atmospheric environment by polyurethane foam (PUF) and quartz filter through the analysis by GC/MS/MS (8/2014~7/2015); 4) to assess the exposures of BPA in Taiwan by determining the associated concentrations in indoor air, indoor dust, and atmospheric environment (8/2015~7/2016).雙酚 A環境樣本分析暴露評估固相微萃取非平恆採樣Bisphenol AEnvironmental Sample AnalysisExposure AssessmentSPMENon-Equilibrium Sampling
