塞拉菲尔德海上排放的碳- 14是核燃料工业全球总剂量的最大贡献者。因此，重要的是要了解这些排放物的命运超出了对这种高流动性放射性污染物的经验分析调查的限制和范围。Ecopath with Ecosim （EwE）被广泛用于模拟人类对生态系统的影响，如渔业，尽管很少有EwE研究模拟生物可利用污染物的命运。这项工作首次提出了一个时空碳模型，利用EwE软件的最新发展来预测海洋环境中人为碳的生态命运。该模型预测了观测到的不同物种间和不同时间内碳活动的趋势。这也为塞拉菲尔德14c在高营养水平物种中的整合提供了证据。
Sellafield marine discharges of14C are the largest contributor to the global collective dose from the nuclear fuel industry. As such, it is important to understand the fate of these discharges beyond the limitations and scope of empirical analytical investigations for this highly mobile radioactive contaminant. Ecopath with Ecosim (EwE) is widely used to model anthropogenic impacts on ecosystems, such as fishing, although very few EwE studies have modelled the fate of bioavailable contaminants. This work presents, for the first time, a spatial-temporal14C model utilising recent developments in EwE software to predict the ecological fate of anthropogenic14C in the marine environment. The model predicted observed trends in14C activities between different species and through time. It also provided evidence for the integration of Sellafield14C in species at higher trophic levels through time.
