Specifikacia Internal Phosphorus Loading in Lakes: Causes, Case Studies, and Management Spears Bryan
Nutrient enrichment of lakes is a ubiquitous problem, impacting ecological and human health on a global scale by accelerating the pace of eutrophication, often resulting in algal blooms, depleted dissolved oxygen concentrations, and economic harm to surrounding communities. In many lakes, bed sediments are a major but unrecognized source of phosphorus to the water, a process known as internal phosphorus loading. Internal loading is notoriously difficult to measure and manage given the need to access processes operating on and within the lakebed. In addition, climate change threatens to promote internal loading. For example, warming of lakes can increase the release of phosphorus from sediments due to 1) longer and stronger periods of lake stratification resulting in sediment anoxia and 2) enhanced microbial decomposition of organic matter. Degraded water quality not only impairs
