Andrade P. Marcet L. Fernández Feal C. Fernández Feal E.F. Covelo F.A. Vega Ciencias de la Tierra oil spill marsh soils heavy metals hydrocarbons The objectives of this study were to determine the effect of the Prestige oil spill on the total petroleum hydrocarbons andheavy metal contents of soils in two marshes (Lires and Villarrube, Galicia, Spain) and the relationship between their oxidationreductionpotential and the solubility of heavy metals with sulfide and sulfate contents. Soil samples were taken from pollutedand unpolluted areas and their petroleum hydrocarbon contents, heavy metal contents and other chemical characteristics weremeasured. The soils affected by the oil spill show remarkable contents of Cr, Cu, Ni, Pb and V. The Lires marsh soils are moreaffected by fuel oil than Villarrube marsh. The effects of the contaminating agents on the soils reach distances of up to 500 mfrom the coastline. In the first 400 m, there are important spatial variations because the fuel oil penetrated into the soils throughtidal action and not directly. The Cr, Cu, Ni, Pb and V contents of polluted soils were between 50 and 200 times higher than thoseof their unpolluted counterparts and the background concentrations in Galician coastal sediments. In the case of Cr, Cu, Ni, Pband V, their originthrough the fuel oil was corroborated by the high correlation (r > 0.90) between the concentrations of thesemetals and the total petroleum hydrocarbon content of the polluted soils, which shows the combined addition of these metalsthrough the fuel oil 2004 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48030309 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.3 Vol.30 |
