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 siteand 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.
