Abstract-The issue of heavy metal toxicity has received considerable attention in aquaculture field. Most studies of heavy metal in aquaculture have only focused on fish species and molluscs but not prawn. Thus, the key research objective of this study is to identify and study selected heavy metals in Penaeus vannamei in the study area. In this study, the mature prawns (5 months old) were collected and 1g of sample is digested using H 2 SO 4 and HNO 3 for 2 hours and filtered. The heavy metal concentration in prawn samples is determined using ICP-OES. The major heavy metals in the prawn head and shell are dominated by Fe>Cu>Zn>Cr>Mn>Ni while in prawn flesh is Fe>Zn>Cu>Cr>As>Ni>Mn. In this study, the highest heavy metals toxicity are prawn head> prawn shell> prawn flesh. In this study, it was found that most of the heavy metals are accumulated in the head of prawn whereas the least is in the shell of prawn.

“…Hence, aquaculture which uses water from the river, estuary and coastal area is prone to external pollution and the produce (fish, prawns) can be a health risk if consumed. This is potentially serious as aquaculture grows rapidly especially for prawn, a high value seafood whose consumer demands far exceeds the supply [2], [3].…”

“…The relationship between different cancers and consumption of dried salted fish has been discussed by many researchers (Armstrong et al, 1998;Sharif et al, 2008;Al Bulushi et al, 2009). Increasing rates of carcinoma is usually attributed to the presence of biogenic amines and nitrosamines.…”

“…According to previous studies by Sharif et al [14], salt content analysis on "belacan" samples obtained from Malacca was 20%, whereby Sumino et al [15] found that "belacan" processed in Malaysia contain approximately 24.1% salt. According to Malaysian Food Act 1983, the standard of salt content for "belacan" should be around 15%.…”

This study was conducted to observe the genotoxic effects of aqueous, methanol, hexane and dichloromethane extracts of "belacan" (shrimp paste) taken from three local districts in Melaka, Malaysia (Kelemak, Batang Tiga & Pantai Puteri). The umu test which was used as the screening test was conducted with and without the presence of metabolic activation system. Without the presence of metabolic activation system, aqueous extracts from Kelemak showed mutagenicity activity at 5 mg/ml with IR (Induction Rate) = 1.52 ± 0.57 and the methanol extracts showed mutagenic activities at 0.625 mg/ml and 5 mg/ml, which the IR was the highest at 5 mg/ml (2.08 ± 0.09). On the other hand, sam-ples from Batang Tiga, Melaka showed mutagenic effects at all five concentrations for the dichloromethane extract, with IR = 2.09 ± 0.64 as the highest value at 1.25 mg/ml. Methanol extracts also showed positive results at 1.25 mg/ml and 2.5 mg/ml with IR = 1.70 ± 0.33 and IR = 2.12 ± 0.51 respectively, and aqueous extract at 0.625 mg/ml with IR = 1.54 ± 0.48 and 5 mg/ml with IR = 1.74 ± 0.50. There was a significant difference of the mean values of IR between the four different types of "belacan" extracts from Batang Tiga (p < 0.05). All four "belacan" extracts from Pantai Puteri, Melaka did not show any mutagenic effect. With the presence of metabolic activation system, there was no mutagenic effect observed in all four extracts from the three districts. Further study to analyze the contents in the food samples should be done in the future to determine the possible contents in the food samples that might be responsible for the mutagenic activities.
