Acidic deposition has an important effect on the transport and speciation of soluble aluminum. Toxicity of aqueous aluminum seems to be strongly dependent on aluminum speciation and the presence of complexing ligands such as fluoride. A study is reported of the complex formation kinetics of AlF/sup 2 +/ in the environmentally significant pH range 2.9-4.9. The pH and temperature dependencies of the overall rate of reaction are discussed along with environmental implications for areas subjected to acidic deposition. 22 references, 6 figures, 4 tables.
