Most of the studies on polybrominated biphenyls (PBB) have been on toxicological evaluations. Very few studies have dealt with their persistence and concentration potential in several environmental matrices such as soil, sediments, and biota as a function of matrix properties. The understanding of these relationships will form some basis for assessing the characteristics of the contaminant's be...

Nanotechnology in medical applications: possible risks for human health While products based on nanotechnology are actually reaching the market, sufficient knowledge on the associated toxicological risks is still lacking. Reducing the size of structures to nanolevel results in distinctly different properties. As well as the chemical composition, which largely dictates the intrinsic toxic proper...
