Abstract
    The pollution of eight pleasure harbours on the Provençal seashore by cadmium, copper, mercury, lead and zinc has been studied using edible urchins Paracentrotus lividus and mussels Mytilus galloprovincialis as bio-indicators. The determination of the degree of contamination of the mussels and urchins in harbours from small to average size was completed by an in situ study of experimental contamination of test animals placed into suspensed cages in harbours from average to high capacity. Mussels have turned out to be more reliable indicators than urchins but these latter bring interesting and complementary information. The most contaminated organs of the urchins are the digestive tube and the gonads. The study has shown that the degree of contamination of the animals is not always linked to the size of the harbour, but can be modified by outside factors. The responsability of antifouling paints and zinc anods is highly probable. Finally, the study with the help of cages proved to be a good method in the harbours where the test animals have disappeared because of a very high degree of pollution.
