For the purpose of the risk assessment of copper substances from ship hall paint, concentrations of copper spices in seawater were investigated. Therefore, the analysis methods of labile and total dissolved copper were developed. Concentrations measurement of labile and total dissolved copper was performed from many places on Tokyo Bay and other bay in Japan from 2010 to 2012.The total dissolved copper concentrations ranged from N. D. to 4.87 ppb, with labile fraction ranging from N. D. to 3.68 ppb in Tokyo bay. In those results, the rise of labile copper concentration was seen at the Port of Tokyo. This area has a possibility of the influence of the copper eluted from the antifouling paint on vessel. The maximum of the detected labile copper in Tokyo Bay was on the near level as the toxic value of some living things sensitive to copper. The monitoring and the management of copper in seawater are also need in the future.

为了对船舶大厅涂料中的铜物质进行风险评估，对海水中铜香料的浓度进行了调查。为此，建立了不稳定态铜和总溶态铜的分析方法。2010~2012年，在日本东京湾和其他海湾进行了活态铜和总溶态铜浓度的测定。结果表明，东京湾的总溶态铜含量在北纬到4.87 ppb之间，不稳定态含量在北纬到3.68 ppb之间。在这些结果中，东京港不稳定的铜浓度上升。该区域可能存在防污涂料淋洗出的铜对船舶的影响。在东京湾检测到的活性铜的最大值接近一些对铜敏感的生物的毒性值。未来还需要对海水中铜的监测和管理。
