Cambodia is a rapidly developing country in south-east Asia, a region forecast as an outsized source of plastic pollution into the world's oceans. However, to date there has been no large-scale assessment of plastic pollution in the environment within the country. We conducted a comprehensive assessment of plastic items and hotspots across 243 coastal, river and inland sites along the entire coastline of Cambodia, recording 46,927 items in transects throughout the study area. Plastic densities along coastlines were more than ten times those on riverbanks and more than twenty times that of inland areas. Averaging 70 plastic items per metre of coastline, Cambodia has among the highest average loads of whole plastic items recorded on coastlines globally. Single-use plastic bottles were the most abundant whole item recorded, overrepresented by drinking water bottles. Polystyrene foam was the most common fragmented item. We provide specific recommendations to reduce plastic in Cambodia's environment.
柬埔寨是东南亚一个快速发展的国家，该地区被预测为世界海洋中塑料污染的一个重要来源。然而，迄今为止，该国境内环境中的塑料污染还没有进行大规模评估。我们对柬埔寨整个海岸线的 243 个沿海、河流和内陆地点的塑料物品和热点进行了全面评估，在整个研究区域的横截线上记录了 46927 个项目。沿海地区的塑料密度是河岸的十倍以上，是内陆地区的二十多倍。平均每米海岸线有 70 个塑料物品，柬埔寨的整体塑料物品平均负荷是全球记录中最高的之一。一次性塑料瓶是记录中最丰富的完整物品，其中以饮用水瓶居多。聚苯乙烯泡沫是最常见的碎片物品。我们提出了具体建议，以减少柬埔寨环境中的塑料污染。
