  • Regional variation in mercury and stable isotopes of red snapper (Lutjanus campechanus) in the northern Gulf of Mexico, USA

    The presence of total mercury (Hg) in fish tissue and the potential associated health risks has become a global concern in marine ecosystems. Few studies have examined basin‐scale variation in Hg accumulation in marine ecosystems, and determining if Hg concentrations in fish tissue vary across marine ecosystems is a key monitoring question. The present study evaluated Hg concentrations in red ...

  • The effects of mining pollution on subtidal habitats of northern Chile

    Mining is the most important commercial activity in Chile, producing more than 60% of the total national income. In northern Chile, where mining extraction is concentrated, solid and liquid pollutants resulting form copper and iron ore processing are discharged to the ocean. The studies on the effects of mining on coastal marine environments in Chile mainly consist of the evaluation of heavy ...

  • Scientists, a new quota species?

    Globally, marine conservation is high on the agenda. The need to protect and conserve species and habitats from deleterious anthropogenic impacts has never been of more concern than it is currently. However, that is not to say we, as a society, are achieving effective marine conservation, in fact we are far from it. Global summits have come and gone, as have the targets they set for marine ...

  • Coastal zones: achieving sustainable management

    Coastal zones are the link between land and the sea and are unique areas, highly diverse in species, habitats and ecosystems. They are environmentally sensitive and economically valuable, with ecosystems rich in biodiversity also providing benefits such as protection from the elements, food and opportunities for the generation of renewable energy. They are also extremely important to human ...

  • Protected areas

    Protected areas provide a wide range of services in a context of increasing pressures and a rapidly changing environment In addition to their critical role in biodiversity conservation, European protected areas are important for many other reasons. Covering a wide range of ecosystems, including forests, grasslands, wetlands, peat lands, mountain, coastal and marine areas, protected areas ensure ...

  • Methylmercury biomagnification in an Arctic pelagic food web

    Mercury (Hg) is a toxic element that enters the biosphere from natural and anthropogenic sources, and emitted gaseous Hg enters the Arctic from lower latitudes by long‐range transport. In aquatic systems, anoxic conditions favor the bacterial transformation of inorganic Hg to methylmercury (MeHg), which has a greater potential for bioaccumulation than inorganic Hg and is the most toxic form of ...

  • Impacts of Deepwater Horizon crude oil exposure on adult mahi‐mahi (Coryphaena hippurus) swim performance

    The temporal and geographic attributes of the Deepwater Horizon incident in 2010 likely exposed pelagic game fish species, such as mahi‐mahi, to crude oil. Although much of the research assessing the effects of the spill has focused on early life stages of fish, studies examining whole‐animal physiological responses of adult marine fish species are lacking. Using swim chamber respirometry, the ...

  • Determining the effects of freshwater inflow on benthic macrofauna in the Caloosahatchee Estuary, Florida

    Florida legislation requires determining and implementing an appropriate range and frequency of freshwater inflows that will sustain a fully functional estuary. Changes in inflow dynamics to the Caloosahatchee Estuary, Florida have altered salinity regimes which in turn have altered the ecological integrity of the estuary. The purpose of this current project is to determine how changes in ...

  • 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 ...


  • In Your Face (Mask) - Environmental degradation starts to affect us here and now.

    Untitled Document What propelled environmental issues to the forefront of public concern from the late 1960s to the mid 1980s? The problems were in your face and up your nose. The ...

  • Implementing multilateral environmental agreements in Sub-Saharan Africa

    This paper examines how Sub-Saharan Africa has implemented its environmental commitments under international law. The first part of the paper examines the state of the environment in Sub-Saharan Africa. The second part, examines implementation of Multilateral Environmental Agreements generally by looking at some of the factors that influence implementation, and theories of implementation. The ...


  • Auto mechanics find new way to save the environment and money

    Some mechanics have reported a 50% savings in cleaning time by turning to an ultrasonic parts cleaning machine while taking advantage of an ecologically safe alternative to manual cleaning with toxic chemicals. With today's industrial sized ultrasonic cleaners, the speed of ultrasonic cleaning to remove soils is combined with the capacity to clean multiple parts at once. Let's take a look at some ...

  • Performance of passive samplers for monitoring estuarine water column concentrations: 1. Contaminants of concern

    Contaminants enter marine and estuarine environments and pose a risk to human and ecological health. Recently, passive sampling devices have been utilized to estimate dissolved concentrations of COCs, such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). In the present study, the performance of three common passive samplers was evaluated for sampling PAHs and ...

  • Stakeholder involvement for management of the coastal zone

    The European Union has taken the lead to promote the management of coastal systems. Management strategies are implemented by the Water Framework Directive (WFD), the Marine Strategy Framework Directive (MSFD), as well as the recent Maritime Spatial Planning (MSP) Directive. Most EU directives have a strong focus on public participation; however, a recent review found that the actual ...

  • Dissolved Organic Nitrogen Measurement in Reclaimed Water

    Dissolved organic nitrogen (DON) is an emerging concern for wastewater reclamation and reuse communities since DON may react with disinfectants to form carcinogenic nitrogenous disinfection byproducts (DBP) (e.g., haloacetonitriles, N-nitrosodimethylamine (NDMA)) and to affect the speciation of currently regulated DBP (trihalomethanes and haloacetic acids). Also, DON is present in proteins that ...
