Objective

Increasingly, both shipping and port managers address environmental risk in their operations. The aim is to provide relevant indicators of performance and quality based on physical and biogeochemical environmental parameters required to monitor and audit the effectiveness of the management systems and environmental policies put in place in European ports.

Description

Ports are marine basins which through physical topography, bathymetry and/or the various technical constructions are characterized as closed or semi-closed coastal systems with limited water circulation. This can lead to pollution hotspots (Smith et al., 2006), or areas of stagnation due to poor flushing and tidal exchange (Espino et al., 2010). Therefore, pollution within port basins is often poorly dispersed and tend to have long residence times leading to high pollution concentrations. A wide range of pollutants can be found in the air, the water column and the sediments of ports being more or less related to the maritime industry, the ubiquitous problem of TBT and its log-term legacy is a notable example (Macguire, 2000; Bray and Langston, 2006). During the last decade, ports around the world have grown at an extremely high rate due to keeping abreast of drives for international trade and the need to create hub-port distribution centres (e.g. Southampton, UK) (Lee and Ducruet, 2006).

Commercial ports suffer from a wide range of maritime pollutants resulting to their characterization as hot spots for the coastal area. Ports are polluted through discharges from maritime traffic (cargo spills, oily bilge discharges, ballast water (often containing exotic species), antifouling paints and sewage), port activities (sewage, cooling waters, spills), solid waste (dumping), construction and maintenance, dredging (releasing contaminants) (DelValls et al, 2004), shipyards and repair zones (e.g. see He and Morrison, 2001).

Nowadays, both shipping and port managers aim to address environmental risk (Jones, A-M, et al, 2005) Therefore in line with other major industries, they strive to achieve suitable Environmental Management Systems (EMS) and environmental policies. Accordingly, successful port environmental management (Wooldridge, W et al., 1999) should address operations with an emphasis on those with the potential to significantly impact the surrounding environment, and to identify actions to prevent or minimize these aspects. An environmental policy should correspond to any deliberately taken action to manage human activities aiming at prevention, reduction and mitigation of harmful effects, incorporating issues such as air and water pollution, waste and ecosystem management, biodiversity and natural resources protection.

The effectiveness of environmental management actions put in place requires monitoring and assessment and for this purpose physical, biogeochemical and ecological environmental parameters may be utilised as performance indicators. Also, the physicochemical characteristics of the receiving waters into which chemical contaminants will be deposited require consideration as they have potential to influence chemical speciation, mobility, bioavailability, and pollutant toxicity and bioavailability. For example it has long been known that fine sediment, often associated with sluggish port waters, can bind strongly to chemical species leading to a “reservoir” (Macguire, 2000) of slowly released pollutants giving long term effects which may “cascade” upwards to the human food chain (Antizar-Ladislao, 2008).

Physical and biogeochemical environmental parameters should incorporate water and sediment quality as well as species and community characteristics (Ford, et al, 2005; Zonta, et al, 1995). Port managers and environmental regulators should aim at: rational planning of pollution control activities; identification of hot spots and their prioritization; assessment of trends, and evaluation of pollution control effectiveness. This would enable recommendation of remedial measures to improve environmental quality and the continual improvement of environmental performance. Thus these indicators would provide valuable information concerning environmental by acting as performance indicators of the quality of the respective environmental actions. Consequently, they should support sound decisions when developing, shaping and evaluating national and local (EMS) policy.

The current project focuses specifically on the European ports, however results and conclusions could be considered for a more general application, however in a following step.
