TL;DR: In this article, 12 OPE analogs were analyzed in 50 human placentas collected in Eastern China, and the concentrations of the 9 most frequently detected OPEs (Σ9OPEs) ranged from 34.4 to 862ng/g lipid weight (lw).

TL;DR: Investigation of the concentrations, size-specific distributions, and preliminary exposure assessments of 10 organophosphate flame retardants were investigated in suspended particulate matter collected from offices suggested a low risk of exposure to OPFRs for people working in such offices, and inhaled OP FRs would mainly deposit in the head region of the respiratory tract.

TL;DR: In this paper, a 1-year observational campaign at 53 sites with uniform protocols was conducted to investigate the spatial distributions and seasonal variations in atmospheric NH3 on a national scale in China.

TL;DR: The EESI-TOF as mentioned in this paper ionization time-of-flight mass spectrometer was proposed to provide real-time, near-molecular (i.e., molecular formula) measurements at atmospherically relevant concentrations without analyte fragmentation or decomposition.

TL;DR: Novel real-time measurements of highly oxygenated organic molecules in the particle phase are reported using the recently developed extractive electrospray ionization time-of-flight mass spectrometer (EESI-TOF), revealing that condensed-phase reactions rapidly alter OA composition and the contribution of HOMs to the particle mass.
