摘要: Abstract Carbonyl compounds including their concentrations, potential sources, diurnal variations and personal exposure were investigated in six subway stations in-subway trains Shanghai June 2008. The carbonyls collected onto solid sorbent (Tenax TA) coated with pentafluorophenyl hydrazine (PFPH), followed by solvent extraction gas chromatography (GC)/mass spectrometry (MS) analysis of the PFPH derivatives. total carbonyl concentrations train about 1.4–2.5 times lower than stations. A significant correlation (R > 0.5, p
