Chemical and toxciological characterization of e-liquid cigarettes

methods were developed for the quantitative determination of nicotine and its related impurities (HPLC- DAD) and for the flavours diacetyl and acetylpropionyl (HS / GC- MS). Also, screening methods were ...

Determinants of persistent organic pollutant (POP) concentrations in human breast milk of a cross-sectional sample of primiparous mothers in Belgium

determined by GC- ECNI- MS and GC- EI- MS / MS depending on the analytes’ sensitivity. Associations between POP concentrations in breast milk and potential determinants were investigated using two-way ...

Investigation of migrating substances from textile used as food contact material

the safety of these “new” food fabrics. A simple ultra-sound assisted extraction of substances from the fabrics was done with acetonitrile to avoid any compound losses. Both a GC- MS full scan screening ...

Modular Method for the Determination of Polycyclic Aromatic Hydrocarbons in Spices and Dried Herbs by Gas Chromatography–Tandem Mass Spectrometry

s),(benzo[a]anthracene [BaA], chrysene [CHR], benzo[b]fluoranthene [BbF] and benzo[a]pyrene [BaP]), in the wide matrix groupof spices and dried herbs by gas chromatography–tandem mass spectrometry (GCMS / MS). The ...

DETERMINATION OF ALLERGENIC FRAGRANCE INGREDIENTS IN FEMININE ABSORBENT HYGIENE PRODUCTS AND LUBRICANTS

allergenic fragrance ingredients in AHP s and lubricants by evaluating the packaging and labels. Thereupon, the fragrances present in the purchased samples were identified and quantified using GC- MS. The ...

Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills

genotoxic substances in e-liquid flavours. 77 e-liquids, representative for the different flavour categories, were collected on the Belgian market and screened for their chemical composition using GC- MS. By ...

Plasticizers and bisphenol A, in packaged foods sold in the Tunisian markets: study of their acute in vivo toxicity and their environmental fate.

Then, the identified chemical molecules were studied for their environmental fate and tested in vivo for its toxicity in mice models. The food products analyzed using GC- MS / MS indicated the presence of ...

Risk Assessment of Florists Exposed to Pesticide Residues through Handling of Flowers and Preparing Bouquets.

extracted with a multi-residue Quick Easy Cheap Effective Rugged Safe (QuEChERS) method and analyzed by a combination of gas and liquid chromatography tandem mass spectrometry (GC- MS / MS and LC- MS / MS) by ...

Development and validation of a HS/GC-MS method for the simultaneous analysis of diacetyl and acetylpropionyl in electronic cigarette refills

analytical methods have been published for determining e-liquid compositions, but concerns exist with respect to the lack of analytical evaluation. Hence in this study, a new HS / GC- MS-based method was ...
