New BPA Detection Tests
News Dec 07, 2015
Bisphenol A (BPA) is a chemical that is employed in the manufacture of certain materials, including polycarbonate and epoxy resins. Recently, the use of BPA was restricted, which may cause the industry to switch to alternative substances. The chemical structure of many alternatives is close to BPA. To date, little is known about the occurrence of these BPA analogues in food. The JRC-Institute for Reference Materials and Measurements (IRMM) developed suitable analytical methods for the determination of BPA and 12 BPA analogues in complex food. In the future, the need to generate reliable occurrence data may arise. The analytical methods are characterised by high selectivity and sensitivity, allowing the determination of these substances at the sub-microgram per kilogram level.
Stable Beta-Amyloid Dimers Identified in Alzheimer’s BrainsNews
A recent study exploited state-of-the-art mass spectrometry to provide the first direct evidence of beta-amyloid dimers in patients with Alzheimer’s disease and points to the potential of these molecules as biomarkers. Beta-amyloid dimers may be the smallest pathological species that trigger Alzheimer’s disease.
Kitchen Cabinets Can Emit Potentially Harmful CompoundsNews
Probably the last place anyone would want to find airborne polychlorinated biphenyl compounds (PCBs) is in the kitchen, yet that's exactly where scientists detected their presence, according to a new report.READ MORE
