Growth, accumulation and antioxidant response in juvenile carp (Cyprinus carpio) fed a selenium diet

The effects of two Se diets (HSe 1.0 mg kg-1 and LSe 0.25 mg kg-1) were investigated on growth, accumulation and antioxidant response in juveniles of Cyprinus carpio at 0, 30 and 60 days. HSe carp had slightly higher mean weight (W) values than LSe group at 60 days and the Fulton condition factor (K) indicated good fish health for both diet groups.

HSe caused a significant Se accumulation in kidney and liver. Se enhanced the endogenous antioxidant capacity by increasing the glutathione content in HSe liver and kidney. Higher glutathione peroxidase activity was also recorded in both HSe tissues, while higher superoxide dismutase and catalase activities were noted only in HSe liver when compared with LSe carp. Although growth was not impaired in carp, oxidative stress indicators changed differently in both HSe tissues, suggesting that liver and kidney may have a dissimilar susceptibility to oxidative stress induced by the prooxidant factor of Se.

Ecological and sanitary risk associated with organochlorine compound bioaccumulation in populations of anguilla from Mediterranean coastal waters
© Aristotle University of Thessaloniki (6/2009)
Eels are particularly vulnerable to persistent and bioaccumulable pollutants because they have an high content of fats, are univoltine and being benthic, can live for long time - during their growth phase in European fresh and brackish waters - in direct contact with the bottom environment, that in certain cases may be very polluted.

Meso- and macrofauna of the soil as the bio-indicators of the meadow soil polluted by heavy metals
© Aristotle University of Thessaloniki (6/2009)
In order to evaluate the soil contamination by heavy metals and their influence on macrofauna, six habitats have been chosen. The first was situated right next to the motorway the others were 20, 30,40, 150 and approximately1500m away from the motorway. The content of heavy metals was determined in the soil. Humidity and pH of the soil were evaluated as well. The density and diversity of the groups of the fauna analyzed were estimated. The greatest diversity of the macrofauna was detected in the area furthest away from the motorway, where the content of the Pb, Zn, Cd, and Cu was the lowest. It was detected that the density and diversity of the analysed pedofauna groups are affected not only by the content of metals such as Pb, Cd and Zn in the soil, but also by the humidity and pH rate.

Macronutrient and heavy metal accumulation in a Greek fir ecosystem of Taygetos mountain in Peloponnese
© Aristotle University of Thessaloniki (6/2009)
Macronutrient and heavy metals accumulation in the forest floor and soil were investigated in three undisturbed natural forest sites of Greek fir ecosystem of Taygetos mountain in Peloponnese. Dry weight and organic matter of the forest floor ranged greatly, from a high of about 67 and 57 t/ha under to a low of 27 and 14 t/ha respectively.

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.

Die Zonierung des westlichen Mittelmeers und ihre Bedeutung für den Ökosystem- und Biodiversitätsschutz durch Meeresschutzgebiete (Fortsetzung102)
© Lexxion Verlagsgesellschaft mbH (2/2013)
Wie gezeigt, befinden sich Schutzgebiete im Mittelmeer mit Ausnahme des „Pelagos Sanctuary for the Conservation of marine Mammals“ bislang nur innerhalb des maximal 12 Seemeilen breiten Streifens der Küstenmeere der Anliegerstaaten. 103 Da das Pelagos Sanctuary nur den Schutz mariner Säugetiere bezweckt,104 sind marine Schutzgebiete (MPAs) mit einem umfassenderen Biodiversitätsschutz jenseits der Küstenmeere bislang nicht eingerichtet und können demzufolge hier ihre Schutzwirkung nicht entfalten.
