However, it must be emphasised that the comparison between the present results and those obtained from other works rests on a gap of at least three years. The determinations of heavy metal concent

The study done in Poconé focuses on Hg, Cu, Pb, Zn, Fe and Mn. In addition, the study aims to evaluate the level of contamination in sediments, soils an
