| Abstract | This study consisted of examining Cd concentration in cephalopods from the Inner Gulf of Thailand followed by an experiment on bioaccumulation of Cd in green mussel (Perna virulis) at different conditions. Three different species of cephalopods were sampled from main markets along the Inner Gulf of Thailand and analysed for their Cd content. Cd level of the cephalopods Pharoah cuttlefish (Sepia paraonis) from Samuthprakarn contained quite high Cd concentration (2-3 mg/kg dw.). Cd concentration was higher in tentacle part than body part. Most of Cd concentration in cephalopods along Inner Gulf of Thailand were still within standard for food consumption, except for a few samples exceeding the standard have been collected in some area. Due to its efficient as filter feeders capable of removing particles from the water column, green mussel (Perna viriclis) at the growth stage of marketable size was used to investigate bioaccumulation in different condition for 21 days. In normal condition, there were no Cd releases from sediment to effect bioaccumulation of green mussel but turbulent sediment with seawater lead to increase rate of bioaccumulation. For condition spike with cadmium 10 ug/L in seawater, Cd concentration in green mussel increases as a function of time and come to a steady state after 14 days of exposure. Bioconcentration factor at equilibrium was estimated to be 1304. This suggested that green mussel is a sensitive species for biological monitoring of Cd soluble in the seawater |
