The interest in the particulate matter speciation is increased during these last years: in particular, the inorganic fraction is studied for its sanitary implications. In fact, whereas for some elements the toxic effects are well known, for other elements there is little information about it. For instance, in this contest an important role is played by the Rare Earth Elements, e.g. Ce, Eu and Yb. These elements, some of them ubiquitous worldwide, are largely used in different industrial applications (optical fibers and electronics) whereas there are few issues on their physiology properties. In any case, Ce and the other REEs should be considered moderately toxic: recent studies suggest that REEs may bind specifically to endothelial sites in the brain and be relevant to the physiological brain functions. This difficulty is mainly due to their determination: they are at very low levels.. View More»
