Micronuclei (MN), nuclear buds (NB), fragmented-apoptotic (FA) and bi-nucleated (BN) cells were analyzed in Mytilus edulis gills and in kidney erythrocytes of Atlantic cod Gadus morhua collected from three boreal locations in the North Atlantic, representing the pollution gradient originating from aluminium smelter industry (Mosjøen, Norway). Th e highest MN, NB, FA and BN values were measured in mussels from the most polluted site, Halsøy, which is located close to the aluminium smelter works. In Halsøy, a 5.2-fold increase (p < 0.0001) in MN, a 3.4-fold increase in fragmented-apoptotic cells (p = 0.0001), a 1.8-fold increase in nuclear buds (p = 0.0002) and a 1.7-fold increase in bi-nucleated cells (p = 0.0524) was found as compared to the reference site. A diff erence in the incidence of MN (p = 0.0052) and FA (p = 0.0003) were found in mussels from the reference and an intermediate contaminated site (Hundålbukta). A signifi cant diff erence in MN (p = 0.0087) and NB (p = 0.0186) frequencies were observed in fi sh kidney immature erythrocytes from Halsøy and Hundålbukta sites.
