| Popis: | In this paper, the methodology of geochemical prospecting has been applied to the study of the scattering of cadmium, lead, cooper and zinc in the upper part of the Huerva river (Iberian Range, Spain). With this purpose two hundred and eleven samples of river sediments were collected along the upper part of the river. The analytical data, after being statistically processed, were interpreted with the aim of approaching to the main features of the models of scat tering and to infer the main anomalous sources of these heavy metals to the channel. The results of this study prove the existence of multiple, complex sources, with the remarcable presence of sources related to the human presence and activity. However, the system seems to have a good ability to depurate itself. |
