Legal requirements and practice of the transport of healthcare waste within European Union
© Wasteconsult international (6/2010)
Transport of healthcare waste moves enormous quantities within European Union every year and is regulated by European and international legislation on the transport of hazardous goods, according to the classification established internationally by UNO. From a legal point of view, two international instruments have been incorporated in European Law to regulate this sector.

Registration under REACH: The Scope of the Completeness Check and the Legal Consequences in case of an ex post identified Incompleteness
© Lexxion Verlagsgesellschaft mbH (4/2010)
The REACH Regulation requires that any submitted registration dossier should be subject to a completeness check by the European Chemicals Agency (ECHA, hereafter referred to as the “Agency”). In this article, the scope of the completeness check is described and the possible legal consequences of an incomplete dossier are analysed.

Chemical waste processing facility and landfill in Šabac: Legislative barriers and absence of the local public participation

Participation represents an indicator of life quality in a certain community, and must be regulated by laws and included in strategies as an important factor. But, Serbia`s laws have serious conflicts among each other (especially Environmental and Construction laws).

Early warning environmental information for the atmospheric environment: The AIRTHESS system
© Aristotle University of Thessaloniki (6/2009)
The present paper provides information on air quality (AQ) related early warning information provision, environmental information systems, and the way that such systems may support the quality of everyday life. On this basis, the paper presents the AIRTHESS system, being in operation in Thessaloniki, Greece.

Environmentally benign and cost optimal phosphoric acid production through a systematic process design framework
© Aristotle University of Thessaloniki (6/2009)
In the present work we address the cost optimal and environmentally efficient design of industrial scale phosphoric acid production processes. We develop a framework that aims to facilitate the design and optimization of phosphoric acid production processes in order to propose solutions that improve the performance of the existing production technologies. The proposed framework is built upon am iterative procedure where design detail is added to the developed optimum process schemes based on evaluation of the generated designs.

Accumulation of cadmium and lead in the edible parts of the fodder shrub Atriplex halimus L. grown on Cd and Pb contaminated soils
© Aristotle University of Thessaloniki (6/2009)
Cadmium and lead accumulation in above ground edible parts of Atriplex halimus L. which is a widespread C4 xero-halophyte plant in the Mediterranean region, has been investigated, not only for the exploration of its possible use for phytoextraction purposes but mainly for the examination of the possible heath threat that can be caused since saltbushes have been extensively used as livestock fodder reserves in arid and semi-arid counties.

Arsenic contaminated environments: bioremediation perspective from molecular analysis on the bacterial arsenical metabolism
© Aristotle University of Thessaloniki (6/2009)
The metalloid arsenic (As) can be released from geological formations and it is widely used in anthropogenic activities (industry, agriculture, etc.) contaminating several aquatic and soil environments. The arsenate As(V) and arsenite As(III) can be subject to microbiologically oxidation, reduction and methylation reactions. Indeed, bacterial metabolisim of arsenical species in the environment is critical in the As cycle. In the present study, novel aerobic bacterial strains responsible for the oxidation and reduction of As were isolated in water samples supplemented with arsenite or arsenate.

Size distribution of metallic elements in particulate matter from a busy urban area
© Aristotle University of Thessaloniki (6/2009)
This study analyzed size distribution characteristics of metallic elements in airborne particulate matter (PM) collected from a busy urban area in a metropolitan city, Korea. PM samples were collected using an eight-stage cascade impactor during the spring and summer of 2008. Concentrations of the different PM size categories were determined using a micro-balance gravimetric method. Metallic elements on each PM filter were extracted ultrasonically using a 1:1 mixture of hydrochloric and nitric acid.

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.

A new threat from consumer goods coming from closing the loop in a global scale
© Aristotle University of Thessaloniki (6/2009)
The discussion of the assessment and management of chemicals and products at the 1992 Earth Summit in Rio de Janeiro led for example to the creation of the OECD programme Globally Harmonised System of Classification and Labelling of Chemicals (GHS). The World Summit on Sustainable Development in Johannesburg 2002 encouraged countries to implement the GHS, adopted by UN ECOSOC in July 2003, as soon as possible, with a view of having the system operating by 2008.
