Content of macroelements in Avena sativa L., Brassica napus var. oleifera and Lupinus luteus L. after contamination of soil by copper and zinc

The aim of the study was to determine the effect of copper and zinc contamination on macroelements content in plants. Research was located on two alkaline soils which in natural conditions were formed with loamy sand and sandy loam. The soil was contaminated with copper (Cu) and zinc (Zn) at the following rates: 0, 150 and 450 mg/kg of soil.

Oats (Avena sativa L.), oil seed rape (Brassica napus var. oleifera) and yellow lupine (Lupinus luteus L.) were the experimental crops. The effect of metals contaminations on the chemical composition of plants was related to the plant species, soil quality, and kind of metal and metal dose. The effect of contamination on the content of majority macroelements in plants was clearer on loamy sand than on sandy loam. The positive or negative correlation between doses of copper and zinc and content of macroelements was observed in dependence from kind of element, quality of soil and plant species.

The influence of soil – plant factors on the uptake of Cs by two plant species
© Aristotle University of Thessaloniki (6/2009)
To investigate Cs uptake by two different plant species grown on soils with contrasting physicochemical properties, a greenhouse pot experiment was conducted. Soil in each pot contaminated with 40 ug g-1 of Cs in the form of CsCl by spraying the solution in layers. After an equilibration period of two months, the soil of each pot appropriately sowed with seeds of Lolium perenne and Trifolium pratense plants.

Comparison of the effect of heavy metals on the pedofauna of forest and meadow stands
© Aristotle University of Thessaloniki (6/2009)
In order to examine the soil contamination by heavy metals and to estimate its influence on the pedofauna, two forest stands and two meadow stands (located in the vicinity of woody areas) have been chosen. The content of Cd, Ni, Pb, Cu, and Zn in the soil of the stands was investigated using an atomic absorption spectrophotometer. Some environmental parameters were also analyzed, such as temperature, humidity and soil pH. The soil samples were neutral or slightly alkaline. The content of all heavy metals was smaller in the soil of the forest park. Cd and Pb content in the meadow and forest soil of the protected landscape park was high. It was found that in the forest park the density of pedofauna was higher than in the meadow and forest of the protected landscape park.

Effects of Alluminum soil content, on earthworm’s bioaccumulation on organic fields
© Aristotle University of Thessaloniki (6/2009)
The earthworm (Lumbricidae family) can be used in many ecotoxicological tests as a bio indicator and as a soil index in organic agriculture. Earthworms show the greatest rate of metals accumulation among all other species of terrestrial ecosystems. The main objective of our study was to study the accumulation of alluminum in the tissues of the earthworms from organic fields.

Fumarolic alteration products at Sousaki (Greece): occurrence and environmental impact
© Aristotle University of Thessaloniki (6/2009)
Fumarolic alteration crusts and efflorescences have been sampled at the Sousaki solfataric field. Samples have been analysed for mineralogical (XRD) and chemical composition (HNO3 digestion and leaching with distilled water). Results show that mineralogical and chemical compositions (major, minor and trace metals) are controlled by microenvironmental conditions.

Physiological responses of rosemary (Rosmarinus officinalis L.) to salinity and copper nutrition in a nutrient solution
© Aristotle University of Thessaloniki (6/2009)
Salinity and copper deficiency are two factors that inhibit plant growth. This study was conducted to investigate individual and combined effects of salinity and copper nutrition on growth, leaf relative water content and nutrient uptake of rosemary (Rosmarinus officinalis L.).
