Vale Ciencias de la Tierra sediments salt marshes Sarcocornia fruticosa Aboveground plant tissues belowground plant tissues Sixteen PAH compounds (containing three to six rings) were quantified in sediments from the Rosário and Mitrena salt marshes in the Tagus and Sado estuaries, respectively, colonized by Sarcocornia fruticosa, and in belowground and aboveground plant tissues. Sediments from Rosário presented higher PAH concentrations (0.838.71 µg gֿ¹) than those from Mitrena (0.221.63 µg gֿ¹). Levels in belowground plant tissues showed a pronounced contrast between the two marshes: 84165 and 0.150.43 µg gֿ¹, respectively. Belowground material in contaminated layers contained 955 times more PAHs than sediments, while ratios lower than one were obtained in lower contaminated layers. Five- and six-ring compounds predominated (6075%) in sediments and belowground plant material from both sites. Aboveground plant tissues presented no differences in PAH concentrations (0.170.18 ng gֿ¹) and composition in both marshes, only three- and four-ring compounds being detected. Thisnarrow concentration range appears to indicate that atmospheric deposition is the predominant pathway of PAH accumulation in aerial plant tissues. 2008 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48034310 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.3 Vol.34 |
