title: Following the Aznalcóllar toxic spill.
abstract: Ten years after the Aznalcóllar mine spill, the decline in metal contamination in the area is evident. However, some elements are still found in elevated concentrations. In Scrobicularia plana, zinc, lead, and arsenic exceeded health advisory levels at several locations although there is no indication of risks associated with consumption of this mollusc. The estuary seems to have enhanced the bioavailability of arsenic and lead. Research should continue to understand the significance of this contamination.
