Current ecological risk assessment (ERA) schemes focus mainly on bioaccumulation and toxicity of pollutants in individual organisms. Ecological models are tools mainly used to assess ecological risks of pollutants to ecosystems, communities, and populations. Their main advantage is the relatively direct integration of the species sensitivity to organic pollutants, the fate and mechanism of action in the environment of toxicants, and life-history features of the individual organism of concern. To promote scientific consensus on ERA schemes, this review is intended to provide a guideline on short-term ERA involving dioxin chemicals and to identify key findings for exposure assessment based on policies of different agencies. It also presents possible adverse effects of dioxins on ecosystems, toxicity equivalence methodology, environmental fate and transport modeling, and development of stressor-response profiles for dioxin-like chemicals.
目前的生态风险评估（ERA）方案主要侧重于单个生物体中污染物的生物积累和毒性。生态模型是主要用于评估污染物对生态系统、群落和种群的生态风险的工具。它们的主要优点是相对直接地整合了对有机污染物敏感的物种、毒物在环境中的归宿和作用机制，以及关注的个体生物的生活史特征。为了促进 ERA 方案的科学共识，本综述旨在为涉及二恶英化学品的短期 ERA 提供指导，并根据不同机构的政策确定暴露评估的关键发现。它还介绍了二恶英对生态系统的可能不良影响、毒性等效方法、环境归宿和运输建模，以及开发类似二恶英化学物质的应激反应特征。
