Development of an Analytical Strategy for Simultaneous Determination of Multiple Contaminants in Paper Food Packaging
Adam Vavrouš (1), Lukáš Vápenka (2), Kristina Kejlová (1), Jitka Sosnovcová (1), Dagmar Jírová (1)

We developed a method for simultaneous determination of polycyclic aromatic hydrocarbons, polyfluorinated compounds, ink photoinitiators, phthalates and bisphenols in paper food packaging employing GC–MS/MS and HPLC–MS/MS.

METHOD DEVELOPMENT FOR THE SIMULTANEOUS DETERMINATION OF METHYLMERCURY AND INORGANIC MERCURY IN SEAFOOD
Sergio Carneado, Ariane V. Zmozinski, Carmen Ibáñez-Palomino, Àngels Sahuquillo, José Fermín López-Sánchez, Márcia M. da Silva

This work reports the method development for the simultaneous determination of methylmercury (MeHg+) and inorganic mercury (iHg) species in seafood. The study focused on the extraction and quantification of MeHg+ by liquid chromatography coupled to on-line UV irradiation and cold vapour atomic fluorescence spectroscopy (LC-UV-HG-AFS), using HCl 4 mol L-1 as extractant agent.

Leveraging CI-H Mass Defect Plots for the Identification of Halogenated Organic Contaminants
Jonathan D. Byer, Mehran Alaee, Karl Jobst, Grazina Pacepavicius, Joe Binkley

A number of legacy contaminants and other pesticides, as well as a number of previously unknown compounds were tentatively identified in the pooled sample. Cl-H mass defect plots are a useful tool for filtering through complex data for the identification of halogenated contaminants. This technique functions as a screening tool for the identification of unknowns, and in the future, may be used as a form of fingerprinting to compare samples.

Flash Pyrolysis Coupled to GCxGC-TOFMS and GC-High Resolution TOFMS for Characterization of Crude Oil and Petroleum Fractions
Clecio F. Klitzke, Joe Binkley, Jeffrey Patrick

The pyrolysis of asphaltenes from discrete crude oil samples shows distinct composition in terms of light and heavy aromatic hydrocarbons and alkyldibenzo-thiophenes. The use of Py–GC×GC–TOFMS is crucial for the determination of isomeric composition, and Py–GC–HRTOFMS with high resolution and high mass accuracy complements the identification by unequivocal chemical formula assignments. The study of the relationships of the crude oil and asphaltene composition are in progress.

Analysis of Low Levels of Bisphenol A (BPA) in Canned Broths
Ken G. Espenschied, Michael Ye, Olga I. Shimelis, and Christine Dumas

Bisphenol A (BPA) is a primary monomer used in the manufacture of many plastics and epoxies. Some of these plastics are used as beverage containers and as liners and sealants for metal food containers. Because of BPA’s potential to act as an endocrine disrupter at low concentrations in humans, regulations have been enacted regarding BPA concentrations in food and beverages sold for human consumption.

Total Phenolics and Beta-1,3-Glucans Extracted from Medicinal Mushrooms (Ganoderma lucidum, Inonotus obliquus, and Phellinus linteus)
Jaecheol Kim, Kiuk Lee, Keum Taek Hwang(1), Gichun Yoo(2)

This study was to analyze the total phenolics, beta-glucans, and beta-1,3-glucans in water extracts of three medicinal mushrooms (Ganoderma lucidum(GL), Inonotus obliquus(IO), and Phellinus linteus(PL)) under different extraction conditions.
