Title: Utilizing ion mobility spectrometry and mass spectrometry for the analysis of polycyclic aromatic hydrocarbons, polychlorinated biphenyls, polybrominated diphenyl ethers and their metabolites

Abstract

Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) are persistent environmental pollutants originating from incomplete combustion of organic materials and synthetic sources. PAHs, PCBs, and PBDEs have all been shown to have a significant effect on human health with correlations to cancer and other diseases. Therefore, measuring the presence of these xenobiotics in the environment and human body is imperative for assessing their health risks. To date, their analyses require both gas chromatography and liquid chromatography separations in conjunction with mass spectrometry measurements for detection of both the parent molecules and their hydroxylated metabolites, making their studies extremely time consuming. Here in this work, we characterized PAHs, PCBs, PBDEs and their hydroxylated metabolites using ion mobility spectrometry coupled with mass spectrometry (IMS-MS) and in combination with different ionization methods including electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI) and atmospheric pressure photoionization (APPI). In conclusion, the collision cross section and m/z trend lines derived from the IMS-MS analyses displayed distinct trends for each molecule type. Additionally, the rapid isomeric and molecular separations possible with IMS-MS showed great promise for quickly distinguishing the parent and metabolized PAH, PCB, and PDBE molecules in complex environmental and biological samples.

Fig. 1 Fig. 1: a) Representative chemical structures of PAHs, PCBs and PDBEs. PAHs consist of fused benzene rings (i.e. naphthalene, anthracene and benzo(a)pyrene) as shown in the top panel, while the different phenyl linkages and nomenclature of PCBs and PBDEs are shown below. For the PCBs and PDBEs, chlorines and brominesmore » are substituted for hydrogens at the 10 possible positions on the two phenyl rings and they are numbered as 2 to 6 on the first ring and 2´ to 6´ on the second. The 2, 2´, 6 and 6´ positions closest to the diphenyl (or diphenyl ether) bond are described as ortho, while para corresponds to the 4 and 4´ positions and meta has the 3, 3´, 5 and 5´ positions. The number and location of chlorines and bromines determine both the physical and biological activities of each molecule. b) A schematic of ion mobility spectrometry separation principle. Briefly, in an IMS separation, the ions travel through a drift cell filled with buffer gas (i.e. N2) under the influence of a weak electric field. The separation depends on the mass, charge and the shape of the ions. For isomers with the same m/z, compact structures will travel faster than more extended structures.« less
