  • Measurement of TOC in High-Salt Sample

    The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

  • Marine Industry experience with Aalborg Industries

    Port Authorities and Governing Bodies state that a ship cannot emit smoke of >20% opacity for more than 3 minutes when in port. The IMO set similar limits for on-board incinerators. The DSL-220 Opacity Monitor has been used successfully to measure smoke emissions from diesel engines, incinerators and boilers on board ship ensuring that environmental concerns are ...

  • Empirical data and optimal monitoring policies: the case of four Russian sea harbours

    In this paper, we describe the present state of empirical information about oil spills and oil monitoring activities in Russian harbours. We explain how we gathered, organised, and estimated the data needed to run the monitoring efforts optimisation model of Deissenberg et al. (2001). We present, analyse, and discuss the results of the optimisations carried out with this model on the basis of the ...

  • Environmental management plan for port and harbour projects

    Port activities can cause deterioration of air and marine water quality in the surrounding areas due to multifarious activities. Hence, for the determination of levels of pollution, identification of pollution sources, control and disposal of waste from various point and non-point sources and for prediction of pollution levels for future, regular monitoring and assessment are required during the ...

  • Monitoring of brine discharges from seawater desalination plants in the Mediterranean

    Desalination of seawater has become an important and growing industry due to the water shortage in some Mediterranean countries. This activity may result in environmental impacts, mainly generated by the discharge into the sea of the concentrate (brine) produced. Data regarding the dispersion of these hypersaline effluents, and about their effects in the marine ecosystem, are very scarce. The ...

  • 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 ...

  • An empirically tractable model of optimal oil spills prevention in Russian sea harbours

    Based on previous theoretical work by Gottinger (1997, 1998), we propose a simple model of optimal monitoring of oil-related activities in harbour areas that is suitable for empirical estimation within the Russian— Ukrainian context, in spite of the poor availability of data in these countries. Specifically, the model indicates how to best allocate at the steady state a given monitoring budget ...

  • Managing environmental impacts of fishing: input controls versus outcome-oriented approaches

    Fishery management has focused primarily on limiting the total catch of key target species to sustainable levels, but fishery managers and the public are becoming increasingly concerned with environmental impacts of fishing such as damage to habitat and bycatch of non-target species, particularly marine mammals and seabirds. There are two main approaches to managing environmental impacts of ...

  • The analysis of polycyclic aromatic hydrocarbons in marine samples

    Polycyclic aromatic hydrocarbons (PAH) have been determined in marine samples for many years, but have only rarely been included in either national or international monitoring programmes. PAH can arise in the environment from natural sources, oil and petroleum products and combustion processes. Although oil spills influence PAH concentrations in local areas, the major sources of PAH are ...
