  • 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 ...

  • Sunscreens release metals and nutrients into seawater

    Beachgoers are becoming increasingly aware of the potentially harmful effects UV filters from sunscreens can have on coral and other marine organisms when the protective lotions wash off their bodies into the ocean. Now, researchers have studied how sunscreens release different compounds -- trace metals and inorganic nutrients -- into Mediterranean seawater, with unknown effects on marine ...

  • 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 ...

  • 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 ...

  • 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 ...

  • The cold deep currents in the Atlantic Ocean that help shape our climate

    For more than a decade scientists from the National Oceanography Centre in Southampton have been travelling to the subtropical Atlantic to collect data that provide important information about our changing climate. Just 15 miles from the sandy shores and coral reefs of the Bahamas the ocean floor plunges down to depths of over two-and-a-half miles. Along this steep slope dozens of sensitive ...

  • Overarching conclusions presents the outcomes of the 2010 world water week

    Overarching Conclusions This section is based on Stockholm International Water Institute’s conclusions and what we consider as the key threads that emerged from the week. These overarching conclusions are also based on the summary reports from workshops and seminars and the rapporteur theme reports (see next section of this publication). Our interpretation of issues raised from over ...

  • Fertilisers linked to contaminated drinking water in Evros, Greece

    In a new study, samples of drinking water from the north-east of Greece have been found to exceed European limits for nitrates, sulphates and phosphates - chemicals that are linked to health problems such as reproductive disorders and cancer. The research has produced a map of the Evros area showing the location of 64 water sampling sites and found that pollution levels are highest in areas with ...

  • Anaerobic Digestion sees significant growth says latest sector survey

    Anaerobic digestion (AD) has grown significantly in the UK, according to the latest sector survey (ASORI), published today by WRAP. WRAP’s comprehensive study of the Anaerobic digestion sector (which complements the Scottish survey of the organics reprocessing industry – also published today, by Zero Waste ...

  • Soil – the living skin of planet earth

    The soil forms the outer skin of the land masses of Planet Earth. This thin veneer of living material is sometimes only a few centimetres thick and rarely thicker than two or three metres, but it has critical influence on what happens on the surface of the Earth. Soil is our life-support system. It provides anchorage for roots; holds water long enough for plants to make use of it; and holds ...

  • 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 ...

  • U.S. EPA awards $252,000 to Arizona graduate students through research fellowships

These students selected will work on a variety of projects covering topics including drinking water, forestry and nanotechnology. The fellows were selected from Arizona State University and University ...

  • Drawing the Line: Setting a Better, Healthier Ozone Standard

    Most people know about the Ozone hole, the thinning stratospheric ozone levels above Earth’s Polar Regions, but fewer know about ground level ozone. On October 1st, the EPA will be finalizing updated ground level Ozone standards using new research regarding public health and ozone. What does this mean and ...
