| Abstract |
An increased incidence of aneuploidy was recorded in mussel (M. edulis ) embryos from a chemically polluted dock (King's Dock in Swansea), compared with the value for a clean open coast population (Whitsand Bay, southeast Cornwall). At King's 26% of embryos were affected compared with only 8% of those from Whitsand Bay where the occurrence of chromosomal abnormality was similar to the "spontaneous" incidence reported for the corresponding stage in human development. The concentrations of aromatic hydrocarbons and heavy metals in soft tissue were higher in the King's Dock adults compared with those from the Whitsand population, with the most marked increase in the case of hydrocarbons. |
