Abstract
Eutrophication is a process of nutrient enrichment in aquatic ecosystems. Under natural circumstances it occurs over long periods but is accelerated by human activities such as sewage disposal; the rapid increase in nitrate is caused by the application of nutrients and agrochemicals in cultivated areas, and phosphate nutrient levels in standing waters cause extended growth of phytoplankton. The ensuing bacterial decomposition may deplete oxygen levels severely. Muddy sediments are also often formed.
