Aquatic animals are also of use in monitoring radioactive contamination (e.g. Patzer, 1976). Data concerning the dynamics and uptake of heavy metals in aquatic invertebrates were reviewed by Bryan (1976a, .), Wright (1978) and Leland .. (1978). In comparison to these studies with aq

Retrospective and Historical Monitoring, years before the chemical analysis. A number of attempts have been made to trace the changes in pollution levels during the period of man’s increasing influence on the environment. The biological materials used for such studies have included peat, annual growth-rings of trees, bird feathers and hum
