Abstract
Green mussel (Perna viridis) can playing role as bio-indicator or biomonitoring agent for heavy-metalcontaminations in the sea. In this research, the concentrations of four elements Ni, Cu, Zn and Cd in P. viridis and in the serum of rat which orally feed by P. viridis were determined by Atomic Absorption Spectrometry (AAS) following dry acid digestion. Parameter analysis was evaluated by determining confidence limit for the obtained results. The result showed that there was a sequence of heavy-metal content in green mussels sample and laboratory rats serum, such as Ni < Cd < Cu < Zn.Keywords: heavy metals, green mussels, laboratory rats serum, AAS
Highlights
Chemical wastes such heavy metals in seawater ecososystems from anthrophogenic activities input such as industrial effluent, urban runoff, domestic activities etc were serious probleme for aquatic ecosystems (Skoog et al, 1994; Beiras et al, 2003 ; Catsiki et al, 2003; Liu and Kueh, 2005)
Studies reported at several Southeasts country’s coastal water (i.e. Malaysia, Hogkong, Thailand, India and Jakarta bay, Indonesia) that Cu, Zn and Cd have been highly accumulated in the green mussels tissues (Yap et al, 2003, 2004) that can potentially being consumed by human via seafood market activities
Atomic Absorption Spectrometry (AAS) (GBC® 902)/Perkin Elmer for analysis heavy metals in mussels with gas flow condition contain of air- acetilene and wave long (λ) were measured Ni(II) (λ= 232.0 nm), Zn(II) (λ =213.9 nm), Cu(II) (λ= 321.47 nm) and Cd(II) (λ= 228.8 nm)
Summary
Chemical wastes such heavy metals in seawater ecososystems from anthrophogenic activities input such as industrial effluent, urban runoff, domestic activities etc were serious probleme for aquatic ecosystems (Skoog et al, 1994; Beiras et al, 2003 ; Catsiki et al, 2003; Liu and Kueh, 2005). Marine organisms such bivalve molluscs i.e. mussels have the ability to uptake heavy metals contamination from their aquatic environment. Our study was to determine the Ni, Cu, Zn and Cd concentration in the mussel and to determine their concentration in rat laboratory serum which orally feed with P. viridis
