Keywords: Green -lipped mussel Perna viridis, biomonitoring agent, heavy metals ABSTRAK Kertas kerja ini bertujuan untuk mengulas kembali kertas-kertas kerja yang telah diterbitkan menggunakan kupang Perna viridis sebagai agen pemantauan bagi pencemaran logam berat di rantau ini dan khasnya dari Malaysia dan membincangkan pengetahuan yang sedia ada. Juga dicadangkan bahawa penyelidikan lanjutan yang berpotensi pada masa hadapan yang akan menambahkan pemahaman kita dan pengetahuan dalam ekotoksikologi logam berat di Malaysia dengan menggunakan kupang P. viridis. Kajian menggunakan kupang ini boleh dikatakan sebagai sebahagian daripada program 'Mussel Watch' di rantau ini. Kerja-kerja dalam membuktikan P. viridis sebagai agen pemantauan, yang berdasarkan kriteria yang telah dicadangkan bagi sesuatu agen pemantauan yang baik, boleh diterima pakai untuk spesies moluska yang lain.

Keywords: Heavy metals, Perna viridis, east coast of Peninsular Malaysia ABSTRAK Kajian lepas melaparkan kupang Perna viridis adalah bertaburan secara meluas in persisiran pantai barat Semenanjung Malaysia tetapi bukan pada persisiran pantai timur Semenanjung. Dalam kajian ini, pemantauan dan pensampelan telah dilakukan dari Tumpat ke Mersing pada April 2004, tetapi kupang hanya boleh dijumpai pada Nenasi dan Kuala Pontian di persisiran pantai Pahang. Oleh itu, kajian ini memastikan bahawa kupang pada persisiran pantai timur adalah tidak bertaburan meluas seperti pada persisiran pantai barat Semenanjung. Kupang yang disampel telah dianalisis untuk kadmium (Cd), kuprum (Cu), plumbum (Pb) dan zink (Zn) dan kepekatan (J.lg/g herat kering) logam dalam tisu lembut keseluruhan adalah Cd: 1.89-2.13, Cu: 3.84-10.34, Pb: 7.95-8.84 dan Zn: 93.1-119.6. Keputusan menunjukkan bahawa sampel Kuala Pontian menimbun lebih tinggi kepekatan Cu (dalam tinggalan tisu lembut dan mantel) dan Zn (dalam tinggalan tisu lembut, mantel dan otot) apabila dibandingkan dengan Nenasi manakala Cd dan Pb menunjukkan tiada perbezaan yang signifikan (P> 0.05) di antara kedua-dua lokasi. Oleh sebab tiada input dan aktiviti antropogenik pada kedua-dua lokasi, perubahan kepekatan logam yang dibiotimbun di dalam tisu lembut herkemungkinan disebabkan oleh perbezaan yang signifikan dari segi saiz (panjang cangkerang dan lebar cangkerang) dan tahap kemasinan bagi kedua-dua lokasi. Faktarjaktar persekitaran yang lain juga mungkin boleh menyebabkan perbezaan dalam 'bioavailability' logam di dalam persisiran pantai yang dicerminkan oleh kepekatan herlainan di tisu lembut yang berlainan bagi kupang tersebut.

In this study, a polluted site at Kg. Pasir Puteh was assessed for heavy metal pollution by using transplanted caged mussel (Perna viridis) from a relatively clean population, Sg. Melayu; both are located in the Strait of Johore. For control purposes, the P. viridis from Kg. Pasir Puteh were also simultaneously transplanted in Sg. Melayu at the same time. It was found that Zn was the metal which got accumulated fastest in the transplanted mussel while Cd was the slowest. This study indicated that the byssus of Perna viridis was most effective for biomonitoring of Cd, Ni, Pb and Zn, while the shell could be used for the biomonitoring of Cu, Ni and Pb and the total soft tissue for the biomonitoring of Ni since they were able to accumulate and eliminate the respective metals well. By using mussel as a biomonitor, the present study found that Kg. Pasir Puteh, which is located in the eastern part of the Strait of Johore, had significantly higher contamination and bioavailabilities of Cd, Cu, Fe, Ni, Pb and Zn. Therefore, the use of the transplanted caged mussels is very useful for heavy metal assessment purposes since it can increase the validity of data interpretation by minimizing ecological factors.
The concentrations of cadmium, copper, zinc and lead, in the total soft tissues of green-lipped mussel Perna viridis of a wide range of sizes (2-11 cm), were determined from a population at Pasir Panjang. The metal contents (µg per individual) and concentrations (µg per g) of cadmium, lead, copper and zinc were studied in P. viridis to find the relationships with body sizes. Smaller and younger mussels showed higher concentrations (µg per g) of Cd, Pb and Zn than the larger and older ones. The results of the present study showed that the plotting of the metal content, against dry body flesh weight on a double logarithmic basis, gave good positive straight lines; this observation is in agreement with Boyden's formula (1977). This indicated that P. viridis showed a different physiological strategy for each metal being studied, which is related to age.

The concentrations of Cu, Cd, Zn, Pb, Ni and Fe in the different soft tissues of Perna viridis from the west and east coast of The Straits of Johore (SOJ) were determined. Crystalline style (CS) recorded higher accumulation of Cu (west: 58.2 mg/kg dry weight; east: 56.0 mg/ kg dry weight), Cd (west: 9.45 mg/kg dry weight; east: 3.93 mg/kg dry weight), Pb (west: 49.5 mg/kg dry weight; east: 7.07 mg/kg dry weight) and Ni (west: 40.0 mg/kg dry weight; east: 20.2 mg/kg dry weight) than those other soft tissues. Byssus meanwhile recorded high levels of Zn (west: 173 mg/kg dry weight; east: 193 mg/kg dry weight) and Fe (west: 3213 mg/kg dry weight; east: 1221 mg/kg dry weight). By comparing the accumulation of heavy metal concentrations in all the eight tissues, CS and byssus recorded the highest accumulation of heavy metals among all tissues, followed by other tissues namely foot, gill, gonad, mantel, muscle and remainder, which recorded relatively low level on heavy metal concentrations. Generally, the soft tissues recorded higher heavy metal concentrations on the east coast than on the west coast of the SOJ. This indicated a high bioavailability and contamination of the potentially toxic heavy metals on the east coast which was due to various human activities.
Concern over consumption safety of farmed green mussel (Perna viridis) in Marudu Bay rises due to the increasing agricultural activities taking place around the bay. This urges us to conduct a study to determine the status of heavy metals (Cu, Mn, Ni and Zn) content in the mussel and sediment samples from the aquaculture site and its relationship with the environmental parameters. Samples of 120 mussels and sediment were collected and analyzed monthly for one year period. Water parameters including temperature, pH, salinity, dissolved oxygen and current speed were collected in-situ during sampling. The mean content of Cu, Mn, Ni and Zn in the mussel was at 45.81±46.94, 48.55±22.21, 8.66±5.02 and 46.72±17.38, respectively. In sediment, the mean content of the metals was at 39.76±36.13, 276.24±189.32, 61.61±17.83 and 55.99±54.49, respectively. Current study also found that, the mean contents of Cu, Mn, Ni and Zn were generally higher during northeast monsoon and lower during southwest monsoon. In addition, the Mn content in green mussel was above the permissible limit. Hence an in-depth study is needed to ascertain the sources of Mn in the farmed green mussel in Marudu Bay.
