Rapid and efficient removal of boron from deep sea water using synthesized polymer resin
© Aristotle University of Thessaloniki (6/2009)
The present investigation aims to treat the deep sea water using the polymeric resins synthesized in the laboratory. The resin was characterized with IR analysis and the morphology was discussed with SEM images. Further, the resin was distributed in three different bead sizes i.e., 0.25 mm, 0.5 mm and 1.0 mm as to assess their removal efficiency for the boron.

Sorption kinetics of PAH by using various sorbents
© Aristotle University of Thessaloniki (6/2009)
Polycyclic aromatic hyrocarbons (PAH), which are a large group of organic compounds with two or more fused rings, are an important threat to the environment. They occur in the aquatic environment as the result of oil spills, ship traffic, pyrolytic processes, domestic and industrial wastewater discharges.

Composition and distribution of organochlorine pollutants in the sediments and mussels from the Istanbul Strait (Turkey)
© Aristotle University of Thessaloniki (6/2009)
Organochlorine pollutants are ubiquitous and persistent anthropogenic contaminants in the aquatic environment. Since these compounds have an affinity for particulate matter, they can accumulate in sediments and due to their lipophilic nature they tend to accumulate also in organisms. In this study, sediment and mussel samples from the stanbul Strait were analyzed for indicator and 12 dioxin-like polychlorinated biphenyls (PCBs), 17 dioxins/furans congeners and for organochlorine pesticides (OCs).

DECISION SUPPORT TOOL FOR THE MANAGEMENT OF DEBRIS FROM HOMELAND SECURITY INCIDENTS
© IWWG International Waste Working Group (10/2007)
Pollution incidents of national significance can be caused by industrial accidents; natural disasters such as hurricanes, floods, and earthquakes, terrorist attacks; weapons of mass destruction; and disease outbreaks impacting the safety of the U.S. food supply. These incidents require an integrated response from federal, state, and local government. The Department of Homeland Security (DHS) has updated the National Response Plan (NRP) and the National Incident Management System for responding to Homeland Security incidents of national significance. Within the NRP, the DHS has identified 15 National Planning Scenarios that every federal, state and local emergency response agency is to create emergency plans for. Each of these 15 scenarios involves decontamination and disposal of contaminated material.

INFLUENCE OF ULTRASONIC TREATMENT ON SEDIMENTATION AND CONSOLIDATION PROPERTIES OF LAGOON SEDIMENTS: LABORATORY INVESTIGATIONS AND NUMERICAL SIMULATION
© IWWG International Waste Working Group (10/2007)
In the internal channels of Marano Lagoon (in northern Italy), the continuous deposit of sediments, often polluted by contaminants such as heavy metals and organic halogens, hinders navigation and access to harbours. To make them navigable once again, it is necessary to excavate the sea bottom and store the dredged material in confined disposal facilities (CDF) on upland to prevent the release of contaminants into the biosphere. During dredging operations, transport and subsequent storage, sediments undergo several physical processes such as increase in water content, sedimentation, consolidation and desiccation that strongly alter the structure and geotechnical behaviour.

APPLICATION OF WASHING AND ELECTROKINETIC TREATMENTS TO A HEAVY METAL CONTAMINATED SEASEDIMENT
© IWWG International Waste Working Group (10/2007)
Dredging of several hundred million cubic meters of sediments each year from harbors and waterways is mandatory in order to maintain the efficiency of the navigation system. Presently, the most common approach to management of dredged sediments is generally limited to dumping into confined disposal facilities (CDFs), but this solution could create potential concerns such as contaminant exposure and slow dewatering/consolidation (Reddy et al., 2006); in addition, disposal is space-consuming and proper sites can be difficult to find (Nystroem et al., 2006). Conversely, dredged sediments could be used in a valuable way, such as for habitat restoration and creation, beach nourishment, industrial and commercial development, enlargement of harbors and other coastal structures.

PHYSICAL AND CHEMICAL CHARACTERIZATIONS OF MARINE SEDIMENTS COLLECTED IN PORT ENVIRONMENTS AIMED AT SAFE DISPOSAL

Coastal environments have always been strategic locations for the social and economic development of every country. Hence coasts are continuously monitored in order to contain the unavoidable of anthropic activities effects on the delicate equilibrium of marine environments. These checks are particularly important in dock areas which are the core-points for all marine activities such as the transit of large commercial and passenger ships, large and small fishing boats and all the industrial and commercial activities typical of port areas.

CLEANING PROCEDURE ADOPTED FOR THE BEACHES OF THE COSTA SMERALDA CONSORTIUM, SARDINIA
© IWWG International Waste Working Group (10/2007)
During the autumn and winter months huge amounts of dead Poseidonia oceanica are washed up onto the coast each year. The latter is an aquatic marine plant, often commonly termed seaweed, which grows on the seabed meadows in spring and summer, shedding its long linear leaves, having turned from their original green colour to brown, in the autumn. Tons of these leaves are washed up by the waves on the shoreline. The layers of this seaweed along the shore at times reach the height of two metres, often being mixed with relevant amounts of sand.
