This article provides a general introduction to acid sulfate soil materials including those in Muthurajawela, a marsh of high ecological significance on the western coast of Sri Lanka. This peat bog is identified as one of the country's two acid sulfate soils landscapes. It covers ~3000 ha in area and contains a 3 to 7 m thick peat layer. Here we review the acid sulfate soils landscape of Muthurajawela marsh providing a broad description of the marsh, including its environmental setting, soil/peat characteristics along with the threats it faces. Furthermore, we briefly discuss the biogeochemistry of coastal acid sulfate soils (CASS) and the relationship to Muthurajawela. Finally, we discuss potential impacts of acid sulfate soil materials on the Muthurajawela marsh, and thereby, identify gaps in the understanding of the marsh's geochemistry. Our study identified that future investigations are required to assess the acidity status in the marsh, partitioning behaviour of trace elements in acid sulfate soil materials and to assess the impact of salt water intrusion and extreme weather events on acid sulfate soil materials.

本文概述了酸性硫酸盐土壤材料，包括斯里兰卡西部沿海具有高生态意义的沼泽Muthurajawela中的土壤材料。泥炭沼泽被认为是该国两个酸性硫酸盐土壤景观之一。它占地约3000公顷，包含3至7 m厚的泥炭层。在这里，我们回顾了Muthurajawela沼泽的酸性硫酸盐土壤景观，对沼泽进行了广泛的描述，包括其环境，土壤/豌豆特性以及所面临的威胁。此外，我们简要讨论了沿海酸性硫酸盐土壤（CASS）的生物地球化学及其与Muthurajawela的关系。最后，我们讨论了酸性硫酸盐土壤材料对Muthurajawela沼泽的潜在影响，从而确定了对沼泽的理解方面的差距。的地球化学。我们的研究表明，需要进行进一步的调查，以评估沼泽中的酸度状态，微量元素在酸性硫酸盐土壤材料中的分配行为，以及评估盐水入侵和极端天气事件对酸性硫酸盐土壤材料的影响。
