abstract = {Bioavailability of Fe, Cu, Zn, As, Cd and Pb has been studied in 17 samples of surface sediments of the Ria
of Huelva. In all cases, total concentration of these elements is high, especially of Zn (1660,6 ppm),
followed by Cu (1499,9 ppm), Pb (919,2 ppm), As (432,5 ppm) and Cd (2,7 ppm). The highest
concentrations associated with bioavailable fractions are shown by Zn (86% of total concentration) followed
by Cd (76,5%), Fe (59%), Cu (45%), As (32%) and Pb (31%). The main source of metal input are the Tinto
and Odiel rivers, which acidic water (pH < 4) discharge coming from acid mine drainage (AMD) to the
estuary. Acidic water inputs and mixing processes with sea water are the main control in the spatial
distribution of metals and their association with the different target fractions},
