Abstract

A study of the Sonora and Bacanuchi rivers was conducted to assess the mobility and bioavailability of heavy metals. These rivers were affected by a spill caused by the mining activity of the region, which is considered the most important ecological disaster in the modern history of Mexico. BCR sequential extraction was performed to determine geochemical phases in which metals are found. The evaluation of heavy metal contamination was performed using Enrichment Factor (EF) and Geoaccumulation index (Igeo). Sediments showed high concentrations (mg/kg) of Cu (8-716), Cr (8-90), Fe (7,300-52,400), Mn (80-938), Ni (6-48), Pb (14-210) and Zn (41-470). Metal concentrations in geochemical phases exhibited the following order: residual>Fe/Mn oxides> exchangeable>organic matter. The order of mobility and/or bioavailability of metals was: Mn>Cu>Ni>Pb>Zn>Fe>Cr. EF showed an anthropogenic enrichment in both rivers for Cu, Cr, Mn, Ni, Pb and Zn, mainly derived from the mining activity. Values of Igeo were classified as non-contaminated to moderately contaminated. The Bacanuchi river showed moderate to strong contamination of Cu and Pb. The quality criteria comparisons (LEL and SEL) indicate both rivers are contaminated by metals and represent a danger to biota, due to the high metal mobility and bioavailability
