[Course of the level of aliphatic and naphtenic hydrocarbons and of 3,4-benzopyrene in mussels taken in a coast area polluted by a fuel spill].

After a fuel spillage, a coastal zone was polluted and wild Mussels were contaminated by paraffinic and naphtenic hydrocarbons and 3,4-benzopyrene. The evolution of this contamination was followed. Normal levels were re-established after a month and a half. Normal paraffins were metabolised faster.
