Heavy metals in marine sediments have been determined in surface sediments collected in Uranouchi Inlet Bay, Kochi, Japan in order to evaluate their levels and spatial distribution. It is very important issues to evaluate the effects of anthropogenic activities, and redox conditions on heavy metal accumulation in this inlet bay area. XRF core scanner (ITRAX) analysis was performed to assess the influencing factors and potential sources of heavy metal enrichment in the sediments. Here we will introduce some examples and initial results.
