Abstract
Concentrations of trace metals and inorganic ions in proboscis and col lar, branchiogenital, hepatic and anal parts of Ptychodera flava were investigated. Concentration levels of Fe, Cu and Mn were higher in the body parts of mature worms in comparison to juveniles. In general, ma ximum accumulation of trace metals and inorganic ions was observed in the branchio-genital region of mature worms, while Fe and Mg levels we re higher in the anal part of juveniles.
