Bioaccumulation and distribution of Mn and Zn in the total soft tissues, digestive glands, residuals and adductor muscles of the horse mussel Modiolus modiolus from three sites, including industrialized and non-industrialized locations in Eastern Canada, were investigated. Extremely high digestive gland metal concentrations were found in individual mussels, as high as 1819 μg/g Mn wet weight and 1964 μg/g Zn wet weight, with mean values from 358 to 404 μg/g Mn and from 399 to 614 μg/g Zn for the collection sites. High Mn to Zn interrelationships were observed inall types of tissues and at all sites. Between different tissues, Zn was interrelated by linear relationships, and Mn was best described by power curve relationships for all tissue types. In the total soft tissue, Mn and Zn interrelations were fitted to power regression curves with different slopes between the three study sites. This indicated that horse mussel was exposed to different metal levels inthe environments and could be useful for monitoring these metals. The uptake of both metals at extremely high concentrations, the lack of regulation and the occurrence of interactions all suggest that Mn and Zn may play a biological role in horse mussels. Zn and Mn interactions, surprisingly, were not disrupted at the very high concentrations of either metal, which proves that the mechanism of metal interactions does not involve a detoxification role.
