“…), except for some experimental data on the solubility of PGE in different solvents [2, 14, 15, 16 ,17, 18], little is known about the mobility and speciation of this group of elements in the environment [19,20,21]. Similarly, only few data exist on the emission mechanisms and on the characteristics of the emitted particles [18,22,23,24]. Such studies are mostly limited to an assessment of the particle size distribution [2,18].…”
