Levels of six trace metals were measure in Mytilus edulis during a six month period. Patterns of seasonal variation were established and normal ranges of metal burdens in mussels were determined. Metals measured were vanadium, manganese, nickel, copper, zinc and cadmium. Sexually mature M. edulis, between 50 and 60 mm in size, were sampled in Yaquina Bay, Oregon at regular intervals between October 1979 and June 1980. Tissues were combined in two pools, ''somatic'' and ''gonadal''. Flame atomic absorption was used to determine concentrations of manganese, nickel, copper, and cadmium. Vanadium was determined by neutron activation analysis. With the exception of copper, all gonadal tissue burdens were greatest in late winter or early spring, at the time of gametogenesis. Somatic burdens of nickel, manganese, and zinc were maximal in early spring, while copper, cadmium and vanadium fluctuated without regard to gametogenesis or spawning. Zinc concentrations increased dramatically between days 22 and 80. Such increases may be indicative of the onset of gametogenesis. Results suggest that somatic and gonadal tissue should be considered separately when measuring metal levels. 1 table (JMT)
