Matière organique et pollution par les hydrocarbures dans les sédiments superficiels du golfe d'Arzew (mer Méditerranée, Algérie) ArchiMer
Buscail, R; Foudil-bouras, Ae; Pauc, H.
The distribution of global organic parameters (organic carbon, nitrogen, hydrolyzable carbon) was established in surficial sediments of the Gulf of Arzew. Moreover, humic substances, humin and hydrocarbons have provided information on the organic matter origin and evolution in the identified sedimentary areas: prodeltas at the mouth of the dry rivers Cheliff and Macta; muddy mid-deposits and carbonated shallow environments. The higher organic matter concentrations characterize the muddy mid-deposits and especially the western part located near the Arzew and Bethioua harbours (TOC > 0.9 %; Nt = 0.35 % d.w.). The marine origin of the organic matter is supported by low C/N ratios (5-9) in the total sediments and the position in the Van Krevelen diagram of...

The monitoring programme of the ecological and ecotoxicological consequences of the "Erika" oil spill ArchiMer
Laubier, Lucien; Le Moigne, Morgan; Flammarion, Patrick; Thybaud, Eric; Cossa, Daniel.
On December 11, 1999, Erika, an oil tanker flying the Maltese flag and loaded with 31 000 t of heavy fuel oil, was making its way from Dunkirk to Livorno when it encountered difficult weather conditions Southwest of the Brittany coast gale force winds 8 to 9 and 6 mwaves). On the morning of 12th December, the captain broadcast an SOS; his vessel was breaking in two, approximately 30 nautical miles to south of Penmarc'h Point (Fig. 1; Finistère, France). The fore section of the vessel sank during the night of the 12-13 December and the aft section was taken in tow on the morning December 13, but subsequently sank in the early afternoon. Both parts lay in 120 m of water and were located 10 km apart. Approximately, 19 000 t of heavy fuel oil were spilled into...

Bioremediation of diesel/biodiesel contaminated sandy soil in microcosm: evaluation of fungal bioaugmentation and natural attenuation Biological Sciences
Anjos, Noelly Almeida dos; Lima, Suzy Darley de; Rothebarth, Ana Vitória de Paula; Lima, Zoraidy Marques de; Caixeta, Danila Soares; Morais, Eduardo Beraldo de.
  Biodiesel is a clean renewable fuel used as alternative energy source to diesel and it is commercialized as a minor component in diesel blends. Similarly to diesel, biodiesel spill is a source of contamination for the ecosystem making necessary to provide effective remediation strategies. Bioremediation is a technology that has been applied with success to clean up hydrocarbon-contaminated environments. In this study, fungal bioaugmentation strategy was compared with natural attenuation during bioremediation of a sandy soil contaminated with diesel, biodiesel and blends (B20 and B50). Respirometric assays simulating the contamination of soil were carried out in Bartha flasks used to measure microbial CO2 production. Penicillium sp. AV4 isolated from the...
