Dataset of Atmospheric PAHs in Memphis
This dataset contains concentrations (in ng/m3) of 32 polycyclic aromatic hydrocarbons (PAHs) in the ambient air in the Memphis Tri-state Area (MTA) measured every 12 days from March 13th, 2018, to May 25th, 2019.
Steps to reproduce
PAH samples were collected at 19 sites in the Memphis Tir-state Area (MTA) every 12 days from March 13th, 2018, to May 25th, 2019. PAHs in the ambient air were collected onto a quartz fiber filter (QFF) and a sorbent “sandwich” containing polyurethane foam (PUF)/XAD-4 resin/PUF, housed in a high-volume sampler (TE-1000, Tisch Environmental Inc., Cleves, OH). The collection media were extracted together in an accelerated solvent extractor (ASE 350, Thermo Scientific, Waltham, MA), and the extract was concentrated using an automatic evaporator (Turbo Vap II, Biotage, Uppsala, Sweden). The final extract was analyzed for 32 target PAHs on a gas chromatography/mass spectrometry (Agilent 7890B/5977A, Agilent Technology Inc., Santa Clara, CA) system operated in a select-ion-monitoring (SIM) mode.
