Résumé

Butyltins have been used as biocides in antifouling paints for ship hulls, in fungicides, insecticides and wood preservation products and as stabilizers in polyvinyl chloride (PVC) since 1960. Although their use on small vessels is regulated in Canada since 1989, butyltins are still used as antifouling agent by a significant portion of the worldwide commercial fleet. Butyltins can be found in sediments in the form of tributyltin and its degradation products, dibutyltin and monobutyltin. These organic metals are persistent in the environment, bioaccumulate in aquatic organisms and cause toxicity. As a part of collaboration between monitoring and research programs on the chemical contamination in the St. Lawrence River (Canada), we analyzed butlytin in 250 sediment samples carry out in fluvial lakes, commercial harbours, and marinas along the river.
