[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]. / Evolution de la teneur en hydrocarbures aliphatiques et naphténiques, ainsi qu'en 3,4-benzopyrène, de Moules prélevées dans une zone côtière polluée par une nappe de "fuel"

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.

[Bioecological consequences of an accidental hydrocarbon discharge on the rocky shore of the high Normandy coast. Results one year after the oil pollution on the november 26th 1974]. / Conséquences bioécologiques d'un déversement accidentel d'hydrocarbures sur le platier du littoral haut-normand. Bilan un an après la marée noire du 26 novembre 1974

We have followed, during one year, the ecological consequences of an accidental oil pollution on four rocky shores of the norman coast. In the shores where the detergents have not been used, the mussels have progressively excreted the hydrocarbons accumulated in their organism ; the other fixed animals have not been changed. In the shores where the detergents have been used their spreading had not only noxious demoecological consequences, but also synecological consequences with modifications of the fixed species which have colonized the rocks. These observations prove that the use of detergents to clean the polluted shores is not without care.
