Environmental matrices viz, soil, lichen, bryophytes, and epilithic mat were collected and analyzed for major and trace elements from Larsemann Hills, East Antarctica. The biotic community-identified up to genera were algae (21), bryophytes (3) and lichens (2). The average lowest and the highest concentration of trace elements recorded were Hg, Cr for soil; Cd, Zn for lichen; Cd, Sr for bryophyte and Hg, Sr for epilithic mat respectively. The ER and Igeo indicate that Se is highly contaminated in all sample types, whereas; Hg is moderately enriched in bryophytes and lichen. However, the source of contamination is natural. Principal component analyses and cluster analysis identified two natural metal contamination sources: ornithogenic and geogenic. The potential ecological risk index indicates a moderate level of contamination for As, Cr, Cu, and Zn. The element Cd and Hg are a matter of concern from their moderate to high ecological risk in some sites of the LH of Antarctica.","subitem_description_type":"Abstract"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2022.100788"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polar.2022.100788","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Bhakta, Sukumar","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Rout, Tofan Kumar","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Karmakar, Dipti","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Pawar, Chandrakant","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Padhy, Pratap Kumar","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Enrichment ratio","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Geo-accumulation index","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ornithogenic","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Potential ecological risk index","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Principal component analysis","subitem_subject_language":"en","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Trace elements and their potential risk assessment on polar ecosystem of Larsemann Hills, East Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Trace elements and their potential risk assessment on polar ecosystem of Larsemann Hills, East Antarctica"},{"subitem_title":"Trace elements and their potential risk assessment on polar ecosystem of Larsemann Hills, East Antarctica","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"26","path":["2087"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-05-26"},"publish_date":"2022-05-26","publish_status":"0","recid":"16901","relation_version_is_last":true,"title":["Trace elements and their potential risk assessment on polar ecosystem of Larsemann Hills, East Antarctica"],"weko_creator_id":"26","weko_shared_id":-1},"updated":"2023-07-25T12:48:48.972924+00:00"}
