Among organotin species, tributyltin (TBT) shows the longest persistence in the lower trophic levels, and is accumulated in zooplankton up to 150,000 times that in ambient water. Higher ability of zooplankton to accumulate butyltins could be associated with their feeding behaviour as filter feeders. Some zooplankton such as rotifers can accumulate 5 and 2 folds that of alga and mysids, respectively. Generally, meroplankton such as veliger larvae of the mussel (Mytilus edulis) and lobster larvae (Homarus americanus) are more sensitive than the adults. Threshold concentration (i.e. the concentration at which toxicity starts) for acute toxicity in certain copepods is below 0.3mgl(-1) TBTO. Chronic toxicity levels are in the range of one-thousandth to one-tenth part per billion, and generally the No Observed Effects Concentration (NOEC) for zooplankton is 1ngl(-1). The most worrisome are chronic effects on reproduction that could decrease marine-species populations. Long term monitoring programs, including those on zooplankton, for the assessment of the effectiveness of global ban is obviously necessary.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Proceedings of the Horiba International Conference \"New Direction of Ocean Research in the Western Pacific\" : Past, Present and Future of UNESCO/IOC/WESTPAC Activity for 50 years and the JSPS Project \"Coastal Marine Science\"","subitem_description_type":"Other"},{"subitem_description":"Section I: Research Articles/Pollution","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040645","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Coastal Research Center, Atmosphere and Ocean Research Institute, the University of Tokyo"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11957899","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13493000","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"452","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"東京大学大気海洋研究所国際沿岸海洋研究センター"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Faculty of Fisheries and Marine Science, Sam Ratulangi University"},{"subitem_text_value":"Institute of Symbiotic Science and Technology, Tokyo University of Agriculture and Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Rumengan, Inneke F.
