In recent years waterpipe smoking has spread worldwide and emerged as global health issue. Yet only little is known on the composition of waterpipe smoke. Here, we present a study on the identification and quantification of primary aromatic amines (PAAs) in this complex environmental matrix. Smoking of the waterpipe was conducted with a smoking machine and particulate matter was collected on glass fiber pads. We developed a fast, simple and specific liquid chromatography-electrospray ionization tandem mass spectrometry (LC-MS/MS) approach to simultaneously detect 31 different PAAs in this matrix. The detection limits comprised a range of 0.45-4.50ng per smoking session, represented by 2-aminobiphenyl and 3,4,5-trichloroaniline, respectively. Intra- and inter-day precision were determined and proved excellent. We detected 31.3+/-2.2ng aniline and 28.0+/-1.6ng 4,4'-oxydianiline in the smoke of one waterpipe session. The water in the bowl exerted a small but considerable filter effect on PAAs. The method worked-out showed excellent sensitivity and specificity and is thus highly suited for the determination of PAAs in mainstream waterpipe smoke.
