The study of the distribution of trace elements (Sc, V, Cr, Co, Ni, Cu, Zn, Rb, Sr, Y, Zr, Nb, Ba,
Pb, Th and As) in the stream sediments from the Jijia Basin generally indicated that the
environment is either unaffected or slightly affected. Local anomalies determined after defining
the background and the threshold values are due to both anthropogenic factors and geogenic
factors. A particular case is that of Ni, where over 75% of the data exceed the target value.
However, the normal distribution of this element, as well as the high levels of Ni found in some
soils from the studied area, suggest that we are dealing with a geogenically-enriched
environment. The median values for most of the elements contents are close to those determined
for European stream sediments.
