  • A dynamic model of optimal reduction of marine oil pollution

    This paper proposes a system of dynamic models to describe the interactive behaviour of different agents (polluters, inspectors, and a principal pollution control agency) involved in the processes of marine oil pollution and of its prevention and purification, under some realistic assumptions. In particular, short- and long-term economic responses of polluters to monitoring efforts, as well as ...

    The stratification phenomena is the existence of two homogeneous water layers and separated by a thin thermocline layer. In such a case, we can say that the water is stratified. There is no exchange of pollutants through this pycnocline layer. In case we suppose that a pycnocline layer exists, we will be able to check the stability by means of the application of the following equation: ...

  • Integrated Modeling of Fate and Effects of Persistent Organic Pollutants in Marine Ecosystems

    Contaminants reach surface waters through different pathways, ranging from atmospheric deposition, infiltration in the soil during heavy rainfalls and migration with the groundwater or transport in particulate and dissolved phase in rivers. Domestic and industrial sewage water represents a major global source of pollution for surface water. Furthermore, agricultural activities may be associated ...


  • Trans-boundary marine oil pollution and its international legal aspects

    Marine pollution control is a sensitive topic, which has gained importance recently due to crude oil spills which in turn has led to many recent international legal developments. This paper examines the effectiveness of international marine laws in imputing liability and calculating damages where more than one nation is affected. The main international agreements covering the international marine ...

  • Use of marine outfalls in wastewater disposal

    Global experience has shown that disposing of properly treated domestic wastewater through effective ocean outfalls is an economical and reliable strategy for wastewater disposal with minimal environmental impact. Better construction techniques, such as tunnelling, coupled with improved materials mean that the technology of marine wastewater disposal has advanced rapidly in recent years. ...

  • Modelling the effect of atmospheric nitrogen deposition on marine phytoplankton in the Singapore Strait

    Atmospheric deposition is an important source of nutrients to the ocean, potentially stimulating primary production, but its relative effect on coastal eutrophication remains largely unknown. This paper presents data generated by the 3-D modelling program NEUTRO to assess the proportion of atmospheric nutrient fluxes, allowing a quantification of the relative contribution of atmospheric and ocean ...

  • Interdependence between pollution and fish resource harvest policies

    This study presents a bio-economic model in which the dynamics of a fishery are affected by marine pollution both directly and indirectly. From the optimality analysis it can be seen that, as long as a contaminating sector exists near coastal areas, the policy on fish resource harvest will be more intense initially (when the environmental situation is better) and less intense in subsequent ...

  • Effects on Contaminants And Nutrients on The Dynamics of Different Food Webs in Marine Ecosystems

    During the last decades coastal waters have been exposed to growing anthropogenic pressure represented on the one hand by the increase on the input of nutrients and contaminants and on the other hand by the increased exploitation of these areas for aquaculture, fishing and tourism. Some species might be more sensitive than others, but since the different populations are linked to each other by ...


  • Cost-Effective Control of Interdependent Water Pollutants

    Abstract  Excess nutrient loads to coastal waters lead to increased production of algae, which when decaying cause oxygen depletion in bottom sediments, which in turn leads to major changes in marine ecosystems. A cost-minimization model was investigated in which nitrogen and phosphorus were assumed to interact with respect to algae production. It was investigated under what conditions only ...


  • Toxicological effects of short‐term resuspension of metal‐contaminated freshwater and marine sediments

    Sediments in navigation‐dominated waterways are frequently contaminated with a variety of particle‐associated pollutants and are subject to frequent short‐term resuspension events. There is little information documenting whether resuspension of metal‐contaminated sediments has adverse ecological effects on resident aquatic organisms. Using a novel laboratory approach, we examined the ...

  • Biosorption of inorganic mercury onto marine alga Sargassum tenerrimum: batch and column studies

    The potential of Sargassum tenerrimmum algal biomass to remove Hg (II) from aqueous solution is investigated through batch experiments with regard to the influence of solution pH, adsorbent dosage and agitation rate. The algal biomass showed increased sorption capacity with increase in solution pH in the range of 4-7 with the maximum uptake of 3 mmolg−1 at pH 7. For maximum uptake, the optimal ...

  • Simulating the uncertain effect of active carbon capping of a dioxin polluted Norwegian fjord

    Process‐based multimedia models are frequently utilized to simulate the long‐term impacts of pollutants and to evaluate potential remediation actions that can be put in place to improve or manage polluted marine environments. Many such models are detailed enough to encapsulate the different scales and processes relevant for various contaminants, yet still are tractable enough for analysis ...

  • Stochastic models of oil spill processes

    This paper models the occurrence of an environmental accident as a stochastic event. In particular, the situation of an oil spill is explored. Characteristics of the ship operator, and the different types of the ship's operating environment determine a stochastic process governing the time patterns and size of spills. It is shown that both the time distribution of different types of oil spill and ...

  • Modelling Mesocosm Experiments

    During the last decades coastal waters have been exposed to an increasing pressure of nutrients and contaminants related to agricultural, industrial and domestic activities. Input from rivers and effluents are one of the major sources of pollution in the coastal area from, but also inputs from atmospheric transport (dry and wet deposition and air-water exchange) can be a major contributor. ...
