Fluorine immission to acid soil in the vicinity of an aluminium smelter in Galicia (NW Spain) and its influence on aluminium dynamics

Purpose The aluminium smelter located in the northern coast of Galicia (NW Spain) is a source of fluoride pollution. Previous papers Gago et al. (Commun Soil Sci Plant Anal 32:2503–2517, 2001, Fluoride 35:110–121, 2002) have identified an area of 3-km radius around the factory being affected by fluoride emissions. This study aims to investigate the influence of fluoride emissions on fluorine concentration and speciation as well as on aluminium speciation in soils in the vicinity of the smelter.
