The application of toxicity test on the specie Atriplex lampa in the risk assessment of oil spills in Patagonian soils

Oil spills near of the Comodoro Rivadavia city (Chubut, Argentina) were studied. Total petroleum hydrocarbon (TPH) is used to characterize the samples and bioassays were carried out using plants as test organisms. The percentage germination (G), the root elongation (R) and the hypocotyls elongation...

Total petroleum hydrocarbon (TPH) is used to characterize the samples and bioassays were carried out using plants as test organisms. The percentage germination (G), the root elongation (R) and the hypocotyls elongation (H) in Lactuca sativa L and two native species to Patagonian region, Atriplex lampa and Prosopis denudans were used as toxicological indexes. It was considered the effect of salinity on the bioassays, based on the measurement of the electrical conductivity of soil (EC). Application of principal component analysis to experimental data showed that the first component accounted for more than 58.3% of variance. The 1st PC is largely influenced by the germination percentage of Lactuca sativa L (GL) and Atriplex lampa (GA), in that order of significance. The second component accounted 16.9% of variance. The 2ndPC is largely influenced by TPH and EC. A simple and direct correlation between TPH and toxicity was not found suggesting that TPH in conjunction with ecotoxicity test would be more successfully tool to define the end point of a remediation. The native specie Atriplex lampa showed to have a similar sensibility to the Lactuca sativa L suggesting that it could be used as a phytoindicator in assessement of environmental risk. Fil:Ríos, S.M.
