Anthropogenic nutrients

The impact of anthropogenic nutrient emissions in the coastal zone is heightened by its chemical speciation. Pollutant nitrogen and phosphorus are delivered to the coastal waters primarily in inorganic form, whereas most of the natural riverine dissolved nitrogen and phosphorus are components of organic compounds, i.e., DON and DOE Thus, the pollutant nutrients are delivered to the coastal waters in a chemical form that can be directly assimilated by coastal plankton, whereas the organically bound (natural) forms must first be remineralized.

The sites in the Swedish Himmer fjord and in Dutch coastal waters provide time-series analagous to those from Helgoland. The Himmer fjord exchanges with the Baltic, so has low salinity. Much of its anthropogenic nutrient comes from a waste water treatment plant, which has in most years been used to strip...

To determine the impact of anthropogenic nutrients or contaminants and natural disturbances (fire, hurricanes, and droughts) on wetlands, the background conditions must be established using a wetland that is not impacted by nutrients, contaminants, and natural disturbances. In many regions, it...
