title: Effects of acidification on the mobility of metals and metalloids: an overview.
abstract: The exchange rates for metals and metalloids between sediments, soils, water and aquatic biota are discussed in terms of normal and acidified ecosystems. Where it is possible, the pathways for a number of toxic elements are presented with special emphasis on the impact of acidification on changing chemical speciation, and on the potential toxicity of such acid-generated chemical species. Concerns for the impact of acidification on the stability of ecosystems, the safety of drinking water, bioaccumulation in fish and in plants are addressed.
