ABSTRACT In three separate experiments, the clam, Rangia cuneata was exposed under and near an oil separator platform in Trinity Bay, Texas for periods of approximately 100 days. The greatest naphthalenes uptake was in those clams exposed beneath the platform. Clams exposed at distances of 150-1,000 m from the platform showed little or no uptake of naphthalenes. In clams returned to the lab and allowed to depurate, most of the accumulated naphthalenes were released though detectable levels remained in some of the clams after 47 days. There was good correlation between the rates of naphthalenes uptake by the clams and naphthalenes levels in the sediments at the different stations. However, clams analyzed by gas chromatographic techniques showed high levels of weathered hydrocarbons suggesting that the sediments are a source of hydrocarbons accumulated by the clams. The results are discussed in relation to the physical features of Trinity Bay which is a very shallow, semi-enclosed body of water with a high suspended sediment load.

Landfarming bioremediation was performed over 2 years on soil heavily polluted with weathered oil and oil derivatives: 23200 mg kg-1 of mineral oil, 35300 mg kg-1 total hydrocarbons, and 8.65 mg kg-1 of total PAHs. During the experiment, mineral oil, total hydrocarbon and PAH concentrations decreased by approximately 53%, 27% and 72%, respectively. A GC/MS-Scan was used to identify the crude oil components that persist after bioremediation treatment of contaminated soil and the metabolites generated during this process. The data shows that in weathered-hydrocarbons contaminated soil, the number of initially detected compounds after the bioremediation process further decreased over a 2 year period, and at the same time several new compounds were observed at the end of experiment. Higher persistence was also shown for heavier n-alkanes and branched alkanes, which could be detected over a longer period of time. The analysis highlights the importance of n-alkanes, their substituted derivatives and polycyclic aromatic hydrocarbons as the most significant pollutants.
