Levels, dietary intake and risk of polybrominated diphenyl ethers (PBDEs) in foods commonly consumed in Nigeria

Bisphenol-A (BPA) in Foods commonly consumed in Southwest Nigeria and its Human Health Risk

“…All reagents and consumables used were of high purity (99.99%) and analytical grade. Acetonitrile and n -hexane were obtained from Merck (Darmstadt, Germany), anhydrous magnesium sulfate and sodium chloride were obtained from BDH Laboratories (UK) as reported elsewhere 43 . Reference standard of BPA was obtained from Sigma-Aldrich (St Louis, MO).…”

“…Sample collection considered in this study was reported elsewhere 43 . Eight different food categories such as meat products, aquatic foods, dairy products, edible oil, eggs, fruits, vegetables, and cereals were selected and collected from 3 local markets in Mile-12, Ile-Epo and Bodija; and 2 superstores in Maryland and Dugbe in Lagos and Ibadan, Southwest Nigeria.…”

“…The advantages offered by QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) technique over the traditional methods of food analysis, which is laborious, time consuming, and requires the use of large volume of organic solvent, have been reported 43,44 . QuEChERS is a simple, rapid, and cost effective sample preparation method 43,44 .…”

“…The advantages offered by QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) technique over the traditional methods of food analysis, which is laborious, time consuming, and requires the use of large volume of organic solvent, have been reported 43,44 . QuEChERS is a simple, rapid, and cost effective sample preparation method 43,44 . This study assesses the levels of BPA in foods commonly consumed in Southwest Nigeria using QuEChERS protocol prior to derivatisation of the extracts and analyses by GC-MS and also evaluates the health risk of BPA exposure from food intake by adult population in Southwest Nigeria.…”

High residue bio-based structural–functional integration epoxy and intrinsic flame retardant mechanism study

“…In 2004 and 2008, the EU had banned several types of polybrominated diphenyl ethers (PBDEs) for their latent hazards. [9][10][11] In a view of ame retardants addition will may lose the mechanical properties of polymers, the introduction of halogenated elements into molecular structure can avoid the decline of comprehensive performance for cured thermosetting. In this work, we used nitrogen-phosphorus synergistically to improve the ame retardancy when simultaneously raise the high temperature char residue and balanced mechanical properties.…”
