Última Estimation par spectrofluométrie des concentrations d'hydrocarbures dans l'eau de mer en Manche Occidentale à la suite du naufrage de l"AMOCO CADIZ" du 30 mars au 18 avril 1978 ArchiMer Marchand, Michel. The oil .pollution,resulting from the "AMOCO CADIZ" tanker spill on the Brittany coast of North Finistere-has affected a very large section of the western Channel, limited for the period covering March 30 to April 18 to the west by the 5°W meridian, to the east by the St-Brieuc Bay, to the north by the 49°20' parallel. The contents of hydrocarbons observed in sea water at different levels show that the whole of water column is contaminated by hy­drocarbons and indicate very probably the pollution of the sedimentary phase in the areas, hited by the drifting sheets.

This paper reports the development of a sensor based on surface-enhanced Raman scattering (SERS) for analyses in sea-water. Polycyclic aromatic hydrocarbons (PAHs) are targeted by these sensors and their detection in situ summons up chemical synthesis and optical development. Firstly, a relevant synthesis of SERS active substrates based on gold nanostructures is presented. Different kinds of substrates have been synthesized under variable experimental conditions to modify some parameters such as i) gold shape, size and distribution and such as ii) chemical functionalization: (i) gold nanoparticles were prepared either by chemical reduction of HAuCl4 or by physical deposition. (ii) Substrates were functionalized by hydrophobic films to allow nonpolar...
