Exploiting knowledge on the mechanistic aspects of radiation effects on living matter, it integrates therefore classical ecotoxicological data for some test species along different effect endpoints gathered for individual organisms. As such, it relies exclusively on the dose-response relationships at the organism level. The approach is limited in light of the extent of both, biodiversity and interaction among species in the environment. Founded essentially on organism-related data, such a method cannot fully meet the actual environment protection objectives that have been set, in the vast majority of situations, at the population- and ecosystem-levels. Furthermore, perturbations induced by stressors within ecosystems cannot be entirely grasped from an exclusive toxicological understanding of the stressor's interaction at the organism level. Such effects only act as triggers of perturbation, which propagate within ecosystems, with ultimate responses that may differ radically from those observed at the organism-level (due to non-linear behaviour of complex inter-population relationships). Also, inter-population relationships, such as predator-prey, are capable of mediating indirect effects by means of which the population actually exposed to the stressor may not be the most affected. This is particularly relevant when considering the long-term ecological effect of chronic exposure to toxicants, like radiation, where  damage may not be most due to the direct radio-toxicological effect of radiation per se (upon individual organisms), but rather to the build up of imbalances between interacting populations within ecosystems as a result of differences in their sensitivity to radiation. This communication, therefore, will discuss the wide array of justifications supporting to widen the scope towards an \"ecosystem approach\" for ecological risk assessment of ionizing radiation, as already adopted in other areas of environment protection (biodiversity, halieutics, etc.).","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"SETAC 6th World Congress/SETAC Europe 22nd Annual Meeting","subitem_description_type":"Other"}]},"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":"BRECHIGNAC, Francois"}],"nameIdentifiers":[{"nameIdentifier":"639659","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bradshaw, Clare"}],"nameIdentifiers":[{"nameIdentifier":"639660","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Carroll, Simon"}],"nameIdentifiers":[{"nameIdentifier":"639661","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fuma, Shoichi"}],"nameIdentifiers":[{"nameIdentifier":"639662","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hakanson, Lars"}],"nameIdentifiers":[{"nameIdentifier":"639663","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jaworska, Alicja"}],"nameIdentifiers":[{"nameIdentifier":"639664","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kapustka, Larry"}],"nameIdentifiers":[{"nameIdentifier":"639665","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawaguchi, Isao"}],"nameIdentifiers":[{"nameIdentifier":"639666","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Monte, Luigi"}],"nameIdentifiers":[{"nameIdentifier":"639667","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oughton, Deborah"}],"nameIdentifiers":[{"nameIdentifier":"639668","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sazykina, Tatiana"}],"nameIdentifiers":[{"nameIdentifier":"639669","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Strand, Per"}],"nameIdentifiers":[{"nameIdentifier":"639670","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"府馬 正一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"639671","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"川口 勇生","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"639672","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Designing an ecosystem approach for ecological risk assessment of radiation: a path forward for radioecology","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Designing an ecosystem approach for ecological risk assessment of radiation: a path forward for radioecology"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-06"},"publish_date":"2013-02-06","publish_status":"0","recid":"64911","relation_version_is_last":true,"title":["Designing an ecosystem approach for ecological risk assessment of radiation: a path forward for radioecology"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:06:11.415350+00:00"}
