“…The combination of a reasonable resolution of a few microns combined with a detection power in the ppm (10 À6 g g À1 ) range offers possibilities for trace element mapping giving insight in trace element composition. PIXE method has been widely used for trace elemental analysis since Johansson et al (1970) achieved mass detection limits in the region of 10 À12 g. The extensive literature on the subject includes several excellent review articles (Johansson and Johansson, 1976;Owers and Shalgosky, 1974).…”

In this work, PIXE experiments were performed for measuring heavy and light elements' (ranging from aluminium to lead) concentrations inside various polluted and unpolluted soils as well as liquid samples collected from different phosphate factory sewers in the El Jadida-Safi Atlantic coastal region (Morocco). In addition, uranium ((238)U) and thorium ((232)Th) contents were evaluated in the same samples studied by using CR-39 and LR-115 type II solid state nuclear track detectors (SSNTDs). The influence of the phosphate industry wastes on the concentrations of both radioactive and non-radioactive elements of the samples studied was investigated.

“…A tecnica de fluorescencia de raios X pode ser aplicada em aniilises arnbientais, aniilises de solus:oes e iiguas, aniilises de metais, aniilises de solos, rochas, entre viirias outras [33]. Antes de serem realizadas as aniilises, suspensoes e dispersoes devem ser estabilizadas para evitar sedimentas:iio.…”
