  • Trace metal status in marine biological samples: a review

    The literature on trace metal status in marine biological samples is reviewed, taking into account the importance of the subject. Marine organisms accumulate trace metals to body concentrations well above those in seawater. Different marine organisms differ significantly in accumulated tissue and total body concentrations of heavy metals. The present literature survey indicates that more than 26 ...

  • An interlaboratory comparison study for the determination of dialkyl phthalate esters in environmental and biological samples

    A series of interlaboratory comparison exercises were conducted to assess the accuracy of dialkyl phthalate ester (DPE) concentration measurements in environmental and biological samples. Five laboratories participated in analyses to determine DPE concentrations in standard test solutions; marine sediments; three certified reference materials (CRMs), including CARP‐2 (fish muscle) and BCR‐07 ...

  • Marine specimen banking: archive and pollution control for the 21st century

    The oceans have in the past been extensively used as disposal sites for various kinds of waste. The world ocean – being the final sink for many natural and anthropogenic substances – is a "labile" ecosystem, which is and has for a long time been the focal point of extensive interdisciplinary research. Measurements of heavy metals and a suite of various chemical compounds in the marine ...

  • Volunteers in Marine Conservation Monitoring: a Study of the Distribution of Seahorses Carried Out in Collaboration with Recreational Scuba Divers

    Abstract: Seahorses ( Hippocampus) live in tropical and temperate waters. Habitat degradation and fishery overexploitation have led to drastic population declines on a global scale. Population monitoring is therefore essential to determine current status and manage conservation. In this first study in Italian waters on the geographic and ecological distribution of the two ...

  • Attitudes of Europeans towards the issue of biodiversity

    The European Union (EU) is committed to the protection of 'biological diversity', i.e. the variability among living organisms from all sources including, inter alia, terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems1. The EU has been legislating on biodiversity since the ...

  • Water Quality Assessment and Onshore Development in Tropical Waters

    Standards for bacteriological recreational water quality in Puerto Rico are those proposed by US EPA. The standard for primary contact recreational use has both single-sample limits and running- average threshold limits based on historical data developed for the specific site. La Parguera is the site of a Special Marine Reserve and counts among its unusual habitats a phosphorescent bay, important ...

  • Microbial Biodiversity Detection And Monitoring Using Molecular Biology Tools

    Micro-organisms are responsible for the most biogeochemical cycles that shape the environment of earth and its oceans. So far, only part of these organisms has been well studied, especially those living on earth and more considered from an anthropogenic perspective, e.g causing human diseases or providing useful products and services. Further the inability to generate pure culture has hampered ...


  • Deep sea mining: exploration is inevitable

    Despite concern over adverse impacts, deep marine mineral exploration is set to become a global industry, says geologist Chris Yeats. Global demand for metals continues to grow, fuelled largely by increasing populations and the industrialisation and urbanisation of China and India. To meet this demand, the international ...

  • Ocean science for sustainable development: Facts and figures

    Sarah Grimes explores why we need good ocean monitoring, how to get it, and why it still fails Small Island Developing States. Oceans are a critically important component of the Earth system, supporting ecosystem and human health. They regulate the weather and climate; are essential for producing freshwater; and soak up ...

  • What will it take to get plastics out of the ocean?

    From drones to filters to artificial islands, innovators are working to reduce the threat thousands of tons of trash pose to marine ecosystems. A few palm trees stand strong in the salty breeze. Located on the southern tip of the Pacific island chain of Hawaii, Kamilo Beach is an isolated stretch of black volcanic shoreline in the middle of nowhere. Just a few hundred yards ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

  • Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

    Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...

  • Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution

    To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...

  • Types of bioremediation and their modes of action

    An Urgent Call for Change in U.S. Oil Spill Response With Bioremediation Agent Type EA* bearing out as a workable first response alternative to the use of chemical dispersants, contrasting evidence has become even clearer that dispersant use has been a huge failure. Dispersants have proven to be an inadequate response method with more and more studies showing an ...

  • Micro-plastics and the Specac Diamond Compression Cell

    The Environmental Audit Committee has called for a global ban on microbeads, minuscule plastic balls used by the cosmetic and cleaning industries for their abrasive properties (exfoliating face-wash, shower gel, toothpaste, etc). According to ...
