The aim of this study was to get information about the detoxificant responses and heavy metal accumulation in Cristatella mucedo CUVIER, 1798, a freshwater bryozoan. Total glutathione content and enzymatic activities of glutathione peroxidase, glutathione reductase, catalase, glutathione S-transferase, and heavy metal accumulation of lead, cadmium, chromium and nickel were performed on samples of Cristatella mucedo. The colonies were collected from Lake Piediluco (Umbria, Italy) during the summer 1997 and 1999. As a general rule, higher levels of biochemical parameters were evidenced in specimens sampled during 1999, probably in consequence to the highest metal concentration in tissues of this species.

Abstract
The aim of this study was to get information about the detoxificant responses and heavy metal accumulation in Cristatella mucedo CUVIER, 1798, a freshwater bryozoan. Total glutathione content and enzymatic activities of glutathione peroxidase, glutathione reductase, catalase, glutathione S-transferase, and heavy metal accumulation of lead, cadmium, chromium and nickel were performed on samples of Cristatella mucedo. The colonies were collected from Lake Piediluco (Umbria, Italy) during the summer 1997 and 1999. As a general rule, higher levels of biochemical parameters were evidenced in specimens sampled during 1999, probably in consequence to the highest metal concentration in tissues of this species.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
