POPs are subject to a global treaty seeking to reduce and eventually eliminate these chemicals from the environment. Inhibiting the development of effective intervention strategies is a lack of knowledge regarding biological dose-response and cause-effect relationships. The proposed study will develop multiple endpoint assays to investigate these species-specific relationships and undertake a multidisciplinary risk assessment of increasing POP levels to E. superba. The research will fulfil national treaty requirements and represents an excellent opportunity to advance the field of polar and marine POP ecotoxicology. Outcomes will be critical for the sustainable management of a commercial resource and a pressured keystone species.

持久性有机污染物受到一项全球条约的约束，该条约寻求减少并最终从环境中消除这些化学品。抑制有效干预策略的发展是缺乏关于生物剂量-反应和因果关系的知识。拟议的研究将开发多个终点分析来调查这些物种特定的关系，并对POP水平增加到E.Superba进行多学科风险评估。这项研究将满足国家条约的要求，是推进极地和海洋持久性有机污染物生态毒理学领域的绝佳机会。结果对于商业资源和压力巨大的关键物种的可持续管理至关重要。
