To study the pollution characteristics and exposure health risk of perfluoroalkyl substances (PFASs) in road dust, 12 PFASs were analyzed by ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) this study. PFAS concentrations dust ranged from 0.95 to 111 ng·g-1, with an average concentration (25.6±37.2) suggesting large spatial differences between dust. on main roads significantly higher than minor roads, downtown displayed levels suburban roads. Perfluorobutanoic...
In this study, soil samples were collected from the eastern edge of Qinghai Tibet Plateau in December 2019. The level and distribution characteristics organophosphate esters (OPEs) seasonal frozen analyzed, their sources discussed. results showed that target analytes including tri-n-butyl phosphate (TnBP), tris(2-ethylhexyl) (TEHP), tributoxyethyl (TBEP), triphenyl (TPhP), tri(2-chloroethyl) (TCEP), trichloropropyl (TCPP), tris-(2,3-dichloropropyl) (TDCPP) detected with 100% frequency....
Surface soil samples collected at 18 sites from the northeast Tibetan Plateau were used to analyze perfluoroalkyl substances (PFASs) via ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) study concentration levels and sources of PFASs. The results showed that 11 PFASs detected in soil, ω(Σ11PFASs) ranged 0.043-1.573 ng·g-1 with an average 0.398 ng·g-1. PFBA displayed highest level a mean content 0.164 ng·g-1, whereas PFHxA was lowest (0.005 ng·g-1). concentrations...
