  • Dangerously high levels of endocrine disrupting chemicals found in marine sediments

    Endocrine disrupting chemicals (EDCs) can interfere with the hormonal systems of both humans and wildlife. New research quantifying EDCs in marine environments in Greece found concentrations which present significant risks to sediment-dwelling organisms. Reduction and prevention of chemical pollution and subsequent harm to marine ecosystems is a key aim of the EU Marine Strategy Framework ...

  • Atkins appointed to marine framework

    Scottish Water has appointed engineering design consultancy Atkins to its marine survey services framework. The framework, which is worth up to £5 million and runs initially for two years with scope to be extended to eight, has been developed as part of Scottish Water’s efforts to address changes in legislation, including the Water Framework Directive. It has been designed to support water ...

  • Lugworms harmed by marine microplastic pollution

    Microplastic pollution impairs the heath of the marine worms that help maintain sediments for other creatures, new research suggests. This study shows that the energy reserves of lugworms living in sediment contaminated with microplastic particles were reduced by up to 50%. Microplastic pollution, fragments of less than 5 mm, is of increasing concern. Although the pieces are typically formed as ...

  • Coastal structures change marine ecosystems

    The urbanisation of coastal areas and introduction of man-made structures, such as jetties and seawalls, are changing marine environments. A new analysis highlights the impacts of these changes on marine plants and animals and suggests options to manage the detrimental effects. Many of the world's largest cities are in coastal zones and more than 75 per cent of people are expected to live within ...

  • Microbes High in New Orleans Sediments After Hurricanes

    WOODS HOLE, Massachusetts (ENS) - In a new study documenting the microbial landscape of New Orleans and Lake Pontchartrain after Hurricanes Katrina and Rita, scientists report that sediments in interior portions of the city are contaminated with fecal microbes. They say this was a chronic condition in the area before the hurricanes, and that the resulting water quality in ...

  • Sediment pollution should be included in water quality assessments

    The quality of surface water is best assessed using the status of both the water and underlying sediment. A recent study concluded that water bodies risk being misclassified if sediment assessment is not included, which can lead to unnecessary recovery costs. Under the Water Framework Directive1 (WFD), Member States are required to achieve at least 'good water status' for surface water (inland, ...

  • Pollutants released by seafloor trawling affect marine life

    Commercial bottom trawling, the technique of pulling fishing gear across the seabed to catch fish and other seafood, releases pollutants trapped in the seabed, which can negatively affect local marine life and ecosystems. Recent findings from a Norwegian fjord show how mussels can take up high levels of contaminants released by trawling, with important health implications for consumers. ...

  • Mussels: Biomonitoring tools for pharmaceutical pollution in the marine environment?

    Pharmaceutical pollution of marine environments has important biological consequences for aquatic organisms. This study investigated the effects on mussels of treatment with environmentally relevant levels of an antidepressant, fluoxetine, and a beta-blocker, propranolol, using biomarkers including DNA damage. The results showed that mussels are most vulnerable to these drugs in combination. Many ...

  • Hazardous substances in Europe’s fresh and marine waters – an overview

    Hazardous substances in fresh and marine water can harm aquatic life and pose a risk to human health, according to a new report published today by the European Environment Agency (EEA). The report notes that while European legislation to address the issue is relatively strong, new challenges exist including ‘emerging pollutants’ where potential effects are not yet fully understood. ...

  • Disinfecting Marine Vessel Ballast Water with UV

    Disinfecting Marine Vessel Ballast Water with UV -Hanovia UV disinfection system helps operators meet IMO discharge regulations- To assist operators of cruise ships, tankers, semi-submersibles, jack-up rigs and other large ocean-going vessels to meet the International Maritime Organisation’s (IMO’s) ballast water discharge requirements, UV disinfection specialist Hanovia has partnered with ...

  • Mariners should use caution near buoy site

    The U.S. Army Corps of Engineers and other agencies deployed a data buoy off the coast of Block Island, Rhode Island, three years ago to gather information on wave action for a Corps study and the scientific instrument has been providing useful information to scientists, mariners and the general public since that time. One of the main purposes of deploying the data buoy was to acquire wave ...

  • New global marine alliance to tackle bio-invasions

    A new Global Industry Alliance (GIA) was launched this week to tackle the threats of marine bio-invasions caused by the transfer of marine organisms from one environment to another, in ship ballast tanks. Ballast water is carried in cargo ships to provide needed stability. It is taken onboard at the start of every trip a ship makes and then pumped out on arrival. Some organisms in the ballast ...

  • Disinfecting marine vessel ballast water with UV

    To assist operators of cruise ships, tankers, semi-submersibles, jack-up rigs and other large ocean-going vessels to meet the International Maritime Organisation’s (IMO’s) impending ballast water discharge requirements, UV disinfection specialist Hanovia has partnered with three of the world’s leading systems integrators to provide validated, on-board water treatment systems that are easy to ...

  • Marine environment adequately covered despite complex legislation

    More than 200 pieces of English and EU-wide marine environmental legislation have been analysed in a recent review. While complex, the legislation adequately covered all areas of the marine environment, the authors conclude. However, there is opportunity to remove overlap and conflicts between different legislation and improve cross-border co-operation. The world’s oceans are under threat ...

  • Plan to dump sediment on Great Barrier Reef OK`d

    The government agency that oversees Australia's Great Barrier Reef on Friday approved a plan to dump vast swathes of sediment on the reef as part of a major coal port expansion - a decision that environmentalists say will endanger one of the world's most fragile ecosystems. The federal government in December approved the expansion of the ...

  • Contaminated Sediment Removal to begin at Pier 4 by the Port of Tacoma

    The Port of Tacoma began dredging contaminated sediments in Blair Waterway on September 15 in preparation to expand Pier 4. The Port detected a marine biocide, called tributyltin, while completing a dredging inspection for the site evaluation to expand Pier 4 for larger ships. The Port of Tacoma has agreed to complete the cleanup of the sediments, which the U.S. Environmental Protection Agency ...

  • Microplastic pollution’s effects explored for two key marine species: mussels and lugworms

    Mussels exposed to high levels of microplastic pollution display signs of stress, new research has shown. However, levels of exposure were higher than found in the wild and no effect on the energy reserves of either mussels or lugworms was observed in the lab. tests. The researchers caution that longer experiments may be needed to reveal microplastics’ full effects. Worldwide, plastics ...

  • Plastic litter can pass on pollutants and chemical additives to marine wildlife

    New research has provided the first conclusive evidence that microplastics ingested by marine wildlife can transfer toxic pollutants to their tissues. The researchers studied lugworms fed on PVC particles contaminated with either widespread marine pollutants or plastic additives and found that these ‘earthworms of the sea’ absorbed the chemicals into their gut tissue, which reduced ...
