Chemical analysis of a large series of PAHs and POPs in airborne and sediment samples and their contribution to genotoxic, tumorpromoting and endocrine-disrupting effects
© Aristotle University of Thessaloniki (6/2009)
Combined chemical GC and HPLC analyses were successfully used to resolve several hundreds of individual aromatic compounds and different patterns of relative content of PAHs, methylated and nitrated PAH derivatives in various airborne and river sediment samples. Two approaches were used for sample fractionation. The fractionation on a silica column, based on analyte polarity, yielded aliphatic, nonpolar aromatic (containing both parental PAHs and POPs), H2SO4-silicatreated neutral POPs subfraction (in which PAHs were eliminated), semipolar aromatic (containing e.g. nitrated PAHs) and polar aromatic (with oxygenated PAHs, dialkyl phthalates and other, partly unidentified, polar aromatics) fractions.

Production of secondary value-added products from the chemical recycling of PET bottles
© Aristotle University of Thessaloniki (6/2009)
A research effort was undertaken to produce secondary value-added products (dimethacrylated oligoesters) from the products of PET chemical recycling by glycolysis. The final objective was to use these compounds, as potential raw materials for the production of UV-curable formulations, used as enamel paints or coatings for metallic surfaces in automotive industry.

Potential of selected metals to cause Metal Fume Fever: a comprehensive review
© Aristotle University of Thessaloniki (6/2009)
Metal fume fever (MFF) is a disease as old as the metallurgy of brass. It is an industrial acute illness of short duration that occurs when metals are heated above their melting point. It is most common to people with no previous exposure to the fumes or in workers returning to industrial environment after weekend. The disease is a constellation of symptoms, which may include metallic taste, cough, sneezing and tightness of chest, sweating, headache, fever, muscle aches, mouth dryness, nausea, vomiting, leykocytosis and tiredness. It is believed that the disease has an immunopathological basis facilitated by cytokines. The present paper highlights the mechanisms of MFF through the most relevant in vivo and in vitro experiments. Furthermore, each candidate metal is examined in relation to MFF provocation potential.

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.

PHYSICAL AND CHEMICAL CHARACTERIZATIONS OF MARINE SEDIMENTS COLLECTED IN PORT ENVIRONMENTS AIMED AT SAFE DISPOSAL
© IWWG International Waste Working Group (10/2007)
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.

BEHAVIOR OF MERCURY FROM USED BATTERIES IN LANDFILLS OVER 20 YEARS
© IWWG International Waste Working Group (10/2007)
In Japan, used batteries are collected as incombustible municipal waste, and the majority is landfilled. In 1983, it was determined that the used batteries in daily life contained mercury, and the fact the mercury-containing batteries, which were disposed of as waste raised fears of environmental mercury pollution.

Typical fibres used in reinforced plastics are glass- and carbon-fibres. Recently the interest natural fibres has been increasing.

Naturally occurring caprolactam-degrading bacteria isolated from capybara and nutria faeces
© European Compost Network ECN e.V. (9/2000)
In recent decades, there has been increasing interest in the microbial decomposition of epsilon-caprolactam, an intermediate for nylon-6 production. The degradation of caprolactam seems widespread in Pseudomonas spp. The aim of this study was to assess whether organisms able to utilise caprolactam were also present in environments where artificial selection due to the contact with caprolactam was absent.
