  • Human and physical geography affect organic nutrients in streams

    Rainfall causes carbon, nitrogen and phosphorus, dissolved from natural, agricultural and urban sources, to run into rivers. This can affect water quality by promoting eutrophication, pollution and affecting water temperature and clarity. Researchers have recently studied differences in concentrations of these nutrients in streams across Europe. The Water Framework1 and Urban Wastewater2 ...

  • North Sea needs more protection from nutrient inputs

    Reductions in the nutrients nitrogen and phosphorus flowing from rivers into the North Sea have had clear benefits on marine health in coastal waters, according to a recent study. However, the reductions are less effective in improving the condition of deeper offshore waters. Tougher measures to manage nutrient loads and prevent eutrophication are recommended. Reductions in nutrient levels in ...

  • Link discovered between extreme weather event and marine ecological change

    Plymouth scientists have discovered evidence of a direct link between extreme weather events associated with climate change and episodic changes to the ecological conditions and processes of the marine environment of the Western English Channel. These modifications could have significant implications on how our coastal seas function in the future and ultimately, on the goods and services provided ...

  • Development phosphate removal from RO brine

    During Reversed Osmosis (RO) in water purification not only pure water but also a high salt fraction (brine) is generated. In order to prepare this brine for discharge to a sewer system or WWTP Colsen develops a pellet reactor in close collaboration with PEKA Kroef (Odiliapeel, NL). Via co-crystallization of salts on an inorganic “germ” pellets are generated with a diameter of 2 to 8 ...

  • Long-term seawater analysis has global significance

    Since 1988, scientists from the University of Hawaii have been conducting almost monthly deep-sea research expeditions to collect water samples for subsequent laboratory analysis. Originally designed to characterize subtle long-term changes in environments that were believed to be stable, the work has revealed some surprising conclusions. For example, it has become evident that even in these ...

  • Female fish swap sex in polluted, low-oxygen water

    Hypoxia – low levels of dissolved oxygen – can cause genetically female fish to develop into males, new research has found. Hypoxia in aquatic environments is often the result of eutrophication, which is caused by pollution from human activities. The findings suggest that hypoxia could cause fish populations to collapse, with consequences for entire ecosystems. There are more ...
