This paper describes applicability of the passive sampler containing chelating resin enclosed by the plankton net to the monitoring of heavy metals in a sea area. It was showed that amounts of heavy metals (i.e., Ni, Co, Cd, Zn, Pb, Fe, and Mn) and Al collected by the passive sampler approached constant values with the progress in installation time of 61 days in the sea water. We compared actual concentrations of Ni, Co and Mn in the sea water with amounts of these heavy metals collected by the passive sampler. There was the positive correlation between values obtained from the passive sampler in various sites and concentrations of dissolved Ni, Co in the sea water.Some monitoring results obtained from the passive sampler reflected nearly environments of each monitoring site. The correlation of monitoring results between the passive sampler and Pacific oyster on Co, Zn was observed. It was suggested that the passive sampler sampler is applicable to the monitoring for the biological impact assessment of heavy metals in the sea area.
