Effects Of Salinity On The Toxicity Of Ionic Silver And Ag-Pvp Nanoparticles To Tisbe Battagliai And Ceramium Tenuicorne, Ailbhe Macken, Hugh Byrne, Kevin Thomas
Effects Of Salinity On The Toxicity Of Ionic Silver And Ag-Pvp Nanoparticles To Tisbe Battagliai And Ceramium Tenuicorne, Ailbhe Macken, Hugh Byrne, Kevin Thomas
Articles
The toxic effects of polyvinylpyrrolidone (PVP) coated silver nanoparticles (Ag-NPPVP) and ionic Ag, to Tisbe battagliai (Tb) and Ceramium tenuicorne (Ct) were investigated and the usefulness of standardised marine guidelines for ENP risk assessment were assessed. The toxicity of Ag-NPPVP [CtEC50 = 26.6 µg/L, TbEC50 = 7.9 µg/L] and Ag+ [CtEC50 = 2312.2µg/L, Tb EC50 = 90.9 µg/L] to both test species differed, with the silver ENPs being more toxic. In contrast to Ag+ the toxicity of Ag-NPPVP increased significantly with increasing salinity, however, after thorough characterisation it was not …
Analogues Of The Epoxy Resin Monomer Diglycidyl Ether Of Bisphenol F: Effects On Contact Allergenic Potency And Cytotoxicity, Niamh O'Boyle, Tamara Delaine, Kristina Luthman, Andreas Natsch, Ann-Therese Karlberg
Analogues Of The Epoxy Resin Monomer Diglycidyl Ether Of Bisphenol F: Effects On Contact Allergenic Potency And Cytotoxicity, Niamh O'Boyle, Tamara Delaine, Kristina Luthman, Andreas Natsch, Ann-Therese Karlberg
Articles
Diglycidyl ethers of bisphenol A (DGEBA) and bisphenol F (DGEBF) are widely used as components in epoxy resin thermosetting products. They are known to cause occupational and non-occupational allergic contact dermatitis. The aim of this study is to investigate analogues of DGEBF with regard to contact allergy and cytotoxicity. A comprehensive knowledge of the structural features that contribute to the allergenic and cytotoxic effects of DGEBF will guide the development of future novel epoxy resin systems with reduced health hazards for those coming into contact with them. It was found that the allergenic effects of DGEBF were dependent on its …
