| The concentrations of twelve heavy metals in sediments and in female Nereis diversicolor collected in the estuary of the River Aa and in the little harbour of Boulogne were investigated. Concentration variations which were sometimes considerable were found according to the site, the period of the year, the age of the animals and the cations studied. In addition, numerous intermetal correlations were detected in the nereis. Cytochemical and radioautographic studies revealed that the tegument and the gut were two routes of penetration and storage. Moreover, the gut could be a detoxification and excretory site. |

| Les recherches antérieures sur la pollution littorale du Nord de la France, Hydrobios 80 (1) et Hydrobios II (2) pour les sédiments, Mollusques 82 (3) pour les moules et les coques, ont montré l'existence de deux zones côtières plus fortement contaminées : - entre Calais et Dunkerque, les teneurs des sédiments en plomb, cadmium, nickel et chrome sont anormalement élevées, les origines les plus probables de cette pollution étant les dépôts de dragages des ports, et les apports continentaux liés aux activités industrielles portuaires et aux eaux de l'Aa. |
