东南亚是一个高度生物多样性的地区，但据估计，该地区累计造成的海洋塑料污染总量占全球海洋塑料污染总量的三分之一。众所周知，这种威胁会对海洋巨型动物产生不利影响，然而，了解其影响最近被强调为该地区研究的优先事项。为了弥补这一知识差距，我们对东南亚的软骨鱼类、海洋哺乳动物、海洋爬行动物和海鸟物种进行了结构化文献综述，整理了全球范围内的案例以进行比较，并结合区域专家的引导收集了在结构化文献综述期间可能被忽略的其他已发表和灰色文献案例。在东南亚存在的 380 种海洋巨型动物物种中，我们也在其他地方进行了研究，我们发现记录塑料缠绕（n = 55）和摄入（n = 291）的所有出版物中有 9.1% 和 4.5% 是在东南亚国家进行的。在物种层面，东南亚国家公布的缠结案例涉及每个分类群内 10% 或更少的物种。此外，已公布的摄入案例主要针对海洋哺乳动物，而该地区完全缺乏海鸟的摄入案例。区域专家的启发导致东南亚国家分别记录了另外 10 个和 15 个物种的缠结和摄入案例，凸显了更广泛的数据合成方法的实用性。虽然东南亚塑料污染的规模尤其引起海洋生态系统的关注，但即使在纳入区域专家启发之后，对其相互作用和对海洋巨型动物的影响的了解仍落后于世界其他地区。迫切需要额外的资金来帮助整理基线数据，为限制东南亚海洋巨型动物和塑料污染相互作用的政策和解决方案提供信息。
Southeast (SE) Asia is a highly biodiverse region, yet it is also estimated to cumulatively contribute a third of the total global marine plastic pollution. This threat is known to have adverse impacts on marine megafauna, however, understanding of its impacts has recently been highlighted as a priority for research in the region. To address this knowledge gap, a structured literature review was conducted for species of cartilaginous fishes, marine mammals, marine reptiles, and seabirds present in SE Asia, collating cases on a global scale to allow for comparison, coupled with a regional expert elicitation to gather additional published and grey literature cases which would have been omitted during the structured literature review. Of the 380 marine megafauna species present in SE Asia, but also studied elsewhere, we found that 9.1 % and 4.5 % of all publications documenting plastic entanglement (n= 55) and ingestion (n= 291) were conducted in SE Asian countries. At the species level, published cases of entanglement from SE Asian countries were available for 10 % or less of species within each taxonomic group. Additionally, published ingestion cases were available primarily for marine mammals and were lacking entirely for seabirds in the region. The regional expert elicitation led to entanglement and ingestion cases from SE Asian countries being documented in 10 and 15 additional species respectively, highlighting the utility of a broader approach to data synthesis. While the scale of the plastic pollution in SE Asia is of particular concern for marine ecosystems, knowledge of its interactions and impacts on marine megafauna lags behind other areas of the world, even after the inclusion of a regional expert elicitation. Additional funding to help collate baseline data are critically needed to inform policy and solutions towards limiting the interactions of marine megafauna and plastic pollution in SE Asia.
