These results give an indication of the potential of 500-2000 m shell material from greenlipped
mussels (Perna canaliculus) to remove Zn2+ or Cu2+ from aqueous solution. The contact
of aqueous Zn2+ or Cu2+ ions with crushed shell probably resulted in the formation of solidphase
ZnCO3 and CuCO3. Although the retention of Zn2+ (aq) was more effective, compared
with Cu2+ (aq), the results indicate the crushed mussel shell has the potential to significantly
reduce the aqueous concentration of both metals in stormwater.
