This article studies the migration of MOAH from hot melt adhesives used in multilayer laminates into food simulants. First, initial concentration a group compounds selected as markers several was determined by headspace solid phase microextraction coupled to gas chromatography mass spectrometry (HS-SPME-GC-MS), using previously optimised method. Then, fraction and studied. The analysed with fla...
Organosulfur compounds (OSCs) are naturally emitted via various processes involving phytoplankton and algae in marine regions, from animal metabolism, and from biomass decomposition inland. These compounds are malodorant and reactive. Their oxidation to methanesulfonic and sulfuric acids leads to the formation and growth of atmospheric particles, which are known to influence clouds and climate,...
Tetracosahexaenoic acid (THA, 24:6n-3) has been shown to have the strongest ability to suppress accumulation of lipids in HepG2 cells among well-known n-3 highly unsaturated fatty acids, such as EPA and DHA. In this study, a method for mass production of THA was investigated using distributions of THA and DHA in thirty-two marine organisms, such as starfishes, right-eyed flounders, shellfishes,...
