Distribution and exposure assessment of phthalic acid esters (PAEs) in indoor dust of Shanghai
Abstract
ObjectiveTo characterize the distribution and assess the exposure to phthalic acid esters (PAEs) in the indoor dust of Shanghai City.MethodsSamples were collected from 33 sampling sites, including homes, hotels, offices and public places, in Shanghai in 2018, 2019, and 2020. The samples were pretreated by 100 sieves, extracted and concentrated, and then analyzed by gas chromatography-mass spectrometry in selected ion mode (SIM).ResultsResults on the characteristics of PAEs in indoor dust in different places showed that concentrations of PAEs were in a range of skin contact>respiratory inhalation. Exposure risk of PAEs in children is greater than that in adults.
