Investigation of anthropogenic and natural organic inputs in estuarine sediments using hydrocarbon markers (nah, lab, pah)
Provedor de dados: 5
Autores: Bouloubassi, I; Saliot, A.
Surface sediments were collected in the Rhone delta, NW Mediterranean, at two seasons and analyzed for composition of non-aromatic hydrocarbons (NAH), long-chain linear alkylbenzenes (LAB) and polycyclic aromatic hydrocarbons (PAH) by GC and GC/MS following fractionation by normal phase HPLC. Concentrations varied from 21.2 to 166.7 mu/g for NAH, from 2097.9 to 9324.2 ng/g for total PAH and from 342.5 to 2713.0 ng/g for LAB. These levels are comparable to those reported for other coastal areas worldwide in the vicinity of important urban and industrial activities. Detailed analysis permitted identification of several contributions to the bulk sedimentary hydrocarbon mixture from fossil fuel related sources, pyrolytic processes, domestic wastes as well as...
