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.

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.

Microextraction techniques combined with X-ray fluorescence spectrometry for determination of different metal ions in water
Karina Kocot (a), Beata Zawisza (a), Eva Marguí (b), Ignasi Queralt (c), Rafal Sitko (a)

In present work new preconcentration procedures combining microextraction techniques and X-ray fluorescence spectroscopy were developed. Proposed methodologies are promising tools for multielemental analysis enabling detection of natural pollutants in different water samples.

Application of Central Composite Design (CCD) for the Optimization of Ultrasound-assisted Extraction (UAE) of Phenolics from Corn (Zea mays)
Widiastuti Setyaningsih, 1,2 Erwan Duros, 3 Ceferino Carrera, 4 Miguel Palma, 2 Carmelo G. Barroso 2

A new Ultrasound-assisted Extraction (UAE) of phenolic compounds from corn (Zea mays) has been optimized by means of chemometrics tool. The proposed method was validated and successfully applied to the analysis of phenolics content in several corn cultivars.

Metabolism of Eight Model Pharmaceutical Compounds in Rat and Human HepatoPac Versus Liver Microsomes and Suspension Hepatocyte Platforms
Julius O. Enoru, William DeMaio, Adiba Watanyar, Kenneth Draper, Amanda Moore & Okey Ukairo

This poster presents our comparative metabolite profiling analysis of eight model pharmaceutical compounds with various biotransformation reactions using a functionally stable model of primary hepatocytes [micropatterned co-cultures (MPCCs)] in parallel with the traditional liver microsomal and suspension hepatocyte systems.
