Microplastics (MPs) are ubiquitous in marine environment. The prevalence of MPs in coastal and lagoon sediments, and water were studied in two Marine Protected Areas (MPAs); Bundala National Park (BNP) and Hikkaduwa Marine National Park (HNP) in Sri Lanka. Both areas are important for turtles, birds and coral ecosystems, all of which are particularly threatened by MPs. Abundance of MPs was generally higher in both coastal sediments and waters in HNP (111±29 MPs/m for sediments and 0.515±0.054 MPs/m for water) than in the BNP (102±16 MPs/m for sediments and 0.276±0.077 MPs/m for water). The most common shape and polymer type of MPs were fragments and Polyethylene respectively. This research is the first to survey MPs in MPAs in Sri Lanka and provides a baseline of MPs pollution in these environments for future research and management.
微塑料（MPs）在海洋环境中无处不在。本研究调查了斯里兰卡两个海洋保护区（Bundala 国家公园（BNP）和 Hikkaduwa 海洋国家公园（HNP））的沿海和泻湖沉积物及水域中 MPs 的存在情况。这两个地区对海龟、鸟类和珊瑚生态系统都很重要，而这些生态系统特别容易受到 MPs 的威胁。HNP 的沿海沉积物和水域中的 MPs 丰度普遍高于 BNP（沉积物中为 111±29 MPs/m，水中为 0.515±0.054 MPs/m）（沉积物中为 102±16 MPs/m，水中为 0.276±0.077 MPs/m）。最常见的 MPs 形状和聚合物类型分别为碎片和聚乙烯。本研究首次调查了斯里兰卡海洋保护区中的 MPs，为这些环境中的 MPs 污染提供了未来研究和管理的基线。
