选定的植物养分和重金属的积累在快速增长的路易斯安那州盐沼进行了研究。沉积过程被证明是提供大量的植物养分的沼泽。重金属的积累是低的，似乎与自然重金属含量的传入沉积物，而不是从污染源。来自初级生产力的有机碳大部分留在沼泽中，有助于沼泽垂直加积的沉积过程。氮积累在沼泽中的速率高达21克每平方米每年。
The accumulation of selected plant nutrients and heavy metals in a rapidly accreting Louisiana salt marsh was examined. Sedimentation processes were shown to be supplying large amounts of plant nutrients to the marsh. Accumulation of heavy metals was low and appeared to be associated with the natural heavy metal content of incoming sediment rather than from a pollution source. A large portion of organic carbon from primary production remained in the marsh, contributing to the aggradation process of vertical marsh accretion. Nitrogen accumulated in the marsh at rates as great as 21 g per m2 per yr.
