Human exposure assessment to a large set of polymer additives through the analysis of urine by solid phase extraction followed by ultra high performance liquid chromatography coupled to tandem mass spectrometry.
J. Chromatogr. A. 1423 , 111-23, (2015) Polymer items are extensively present in the human environment. Humans may be consequently exposed to some compounds, such as additives, incorporated in these items. The objective of this work is to assess the human exposure to the main additives such as thos... |

Migration of antioxidant additives from various polyolefinic plastics into oleaginous vehicles.
Int. J. Pharm. 257(1-2) , 217-25, (2003) The migration of the antioxidant additives pentaerythrityl tetrakis(3,5-di-tert-butyl-4-hydroxyphenyl)propionate (Irganox 1010) and tris(2,4-di-tert-butylphenyl)phosphite (Irgafos 168) from polyolefinic packaging into oily vehicles was investigated. The polyo... |

Effects of electron beam irradiation on the migration of antioxidants and their degradation products from commercial polypropylene into food simulating liquids.
Food Addit. Contam. 10(4) , 443-52, (1993) The influence of electron beam irradiation on migrational behaviour of additives present in food packaging material was studied. The migration experiments were carried out on irradiated and non-irradiated polypropylene pouches containing aqueous food simulati... |

Organic Secondary Ion Mass Spectrometry: Signal Enhancement by Water Vapor Injection
J. Am. Soc. Mass Spectrom. 21(12) , 2005-10, (2010) The enhancement of the static secondary ion mass spectrometry (SIMS) signals resulting from the injection, closely to the sample surface, of H 2O vapor at relatively high-pressure, was investigated for a set of organic materials. While the ion signals are gen... |

Feasibility study for the development of certified reference materials for specific migration testing. Part 2: estimation of diffusion parameters and comparison of experimental and predicted data.
Food Addit. Contam. 22(2) , 173-84, (2005) This paper describes the second part of a project whose main objective was to develop the know-how to produce certified reference materials (CRMs) for specific migration testing. Certification parameters discussed are the diffusion coefficient, D(P), the resp... |

Combustion products of plastics as indicators for refuse burning in the atmosphere.
Environ. Sci. Technol. 39(18) , 6961-70, (2005) Despite all of the economic problems and environmental discussions on the dangers and hazards of plastic materials, plastic production worldwide is growing at a rate of about 5% per year. Increasing techniques for recycling polymeric materials have been devel... |

Feasibility study on the use of probabilistic migration modeling in support of exposure assessment from food contact materials.
Risk Anal. 30(7) , 1052-61, (2010) The use of probabilistic approaches in exposure assessments of contaminants migrating from food packages is of increasing interest but the lack of concentration or migration data is often referred as a limitation. Data accounting for the variability and uncer... |

Determination of UV stabilizers in PET bottles by high performance-size exclusion chromatography.
Food Addit. Contam. 13(5) , 575-86, (1996) A Size Exclusion Chromatography-High Performance Liquid Chromatography (SECHPLC) method to determine antioxidants and UV stabilizers in PET bottles has been developed. In only a single run a synthetic mixture of the stabilizers was separated and quantified. T... |

Microwave-assisted oxidation of phosphite-type antioxidant additives in polyethylene film extracts.
J. Chromatogr. A. 1175(2) , 154-61, (2007) Two oxidation methods for reducing the analysis time required to determine Irgafos 126 and Irgafos 168 by pressurised liquid extraction (PLE) and high-performance liquid chromatography (HPLC) were optimised and compared. Analyte oxidation was performed using ... |
