  • During periods of highest metal concentrations, reproductivity in <i>Macoma balthica</i> appeared to be suppressed, suggesting a link between metal loads and reproductive success.

  • Declines in silver and copper concentrations coincide with improvements at the treatment facility.

  • Cu loads from the PARWQP strongly influenced Cu bioaccumulation in Macoma balthica through 1988&#150;91.

  • Between 1989&#150;1997, Cu and Zn were more strongly correlated to surrogate measures of urban runoff. This was not the case before 1989.
