Sampling was carried out at the stations in Cat Ba and Do Son every two weeks from February 2002 to March 2004. Low levels of PSP and DA were detected in shellfish samples from both stations, showing seasonal and yearly variation. Toxicity of plankton samples also showed fluctuation, though the clear correlation could not be observed with the shellfish toxicities. HPLC or LC-MSMS analysis provided clear evidence of shellfish contamination with these toxins and indicated the existence of causative microalgae for these toxicities in this area. Several species of Alexandrium such as A. minutum, A. tamiyavanichii, A. ostenfeldii, A. tamarense were found, though the abundance of them was very low. On the other hand, massive bloom of Pseudo-nitzschia occurred in January at both stations. However, these blooms did not always cause the increase of DA level both in plankton and shellfish samples.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040760","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Coastal Research Center, 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":"Institute of Marine Environment and Resources (IMER)"},{"subitem_text_value":"School of Fisheries Sciences, Kitasato University"},{"subitem_text_value":"Asian Natural Environmental Science Center, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Huyen, Nguyen Thi Minh"}],"nameIdentifiers":[{"nameIdentifier":"139503","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Thuoc, Chu Van"}],"nameIdentifiers":[{"nameIdentifier":"139504","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogata, Takehiko"}],"nameIdentifiers":[{"nameIdentifier":"139505","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sato, Shigeru"}],"nameIdentifiers":[{"nameIdentifier":"139506","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takata, Yoshinobu"}],"nameIdentifiers":[{"nameIdentifier":"139507","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kodama, Masaaki"}],"nameIdentifiers":[{"nameIdentifier":"139508","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukuyo, Yasuwo"}],"nameIdentifiers":[{"nameIdentifier":"139509","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-27"}],"displaytype":"detail","filename":"KJ00004354591.pdf","filesize":[{"value":"501.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004354591.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40769/files/KJ00004354591.pdf"},"version_id":"b05079cb-d581-4f12-a0c2-a95450878383"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Paralytic shellfish poisoning","subitem_subject_scheme":"Other"},{"subitem_subject":"Amnesic shellfish poisoning","subitem_subject_scheme":"Other"},{"subitem_subject":"Alexandrium","subitem_subject_scheme":"Other"},{"subitem_subject":"Pseudo-nitzschia","subitem_subject_scheme":"Other"},{"subitem_subject":"Vietnam","subitem_subject_scheme":"Other"},{"subitem_subject":"monitoring","subitem_subject_scheme":"Other"},{"subitem_subject":"Haiphong","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Seasonal variation of paralytic and amnesic shellfish toxicities in bivalves and microalgae in Haiphong area, Vietnam","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Seasonal variation of paralytic and amnesic shellfish toxicities in bivalves and microalgae in Haiphong area, Vietnam"}]},"item_type_id":"4","owner":"1","path":["7205","7204"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-04-05"},"publish_date":"2007-04-05","publish_status":"0","recid":"40769","relation_version_is_last":true,"title":["Seasonal variation of paralytic and amnesic shellfish toxicities in bivalves and microalgae in Haiphong area, Vietnam"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:16:23.244451+00:00"}
