| A study of the Urique River was conducted to determine the presence of the Chemical, spatial and temporal (mobilization) trends of potentially harmful metáis and metalloids in its water and sediments in the rainy and dry seasons. The present study is part of community monitoring projects and the habitat diagnostics from species with risk in this zone. The determination of the heavy metáis in Urique 's river has a special interest because this which is located in an important región for the biodiversity and the cultural diversity inthe Sierra Tarahumara of Chihuahua, México. The objective was to determine the possible contamination originated from anthropogenic activities (mining and settlement), comparing these metal's concentrations with threshold limit of regulated instances. We employed the optical emission with inductively coupled plasma Spectrometry (ICP plasma) and atomic absorption spectrometry (AAS). 41 samples of water and sediments were taken in different points near from settlement and mining along the river. The results obtained were: (1) in water samples were founded concentrations of As, Al and Fe over the máximum limits of Mexican normative and (2) in sediments valúes higher were for As, Hg and Pb according with intemational guidelines (presents in USA and Cañada) | |
