The podzolic soils of the Kola Peninsula, Russia, have in localised areas been highly contaminated with copper and nickel from smelting activities. Migration and retention of these metals were investigated in undisturbed soil columns irrigated with simulated background and polluted precipitation in...

Maisiagala RADON type radioactive waste storage facility was commissioned in 1963 in a marshy, ecologically sensitive locality, where soluble radionuclides easily can penetrate and migrate with groundwater. To assure the requirements of radiation safety, the analysis of radionuclide leakage from the...

A survey was conducted in order to evaluate the levels of available (DTPA extractable) Cd in salt affected and normal soils of Halastra−Kalohori area, located in N. Greece. In this area, phosphogypsum (PG) (a byproduct of P fertilizer industry, occasionally enriched with Cd) has been used as...

Plastic pellets (small granules, 1-5 millimeters in diameter) are widely distributed in the ocean and coastal zones all over the world. They are an industrial raw material for the plastic industry and are unintentionally released to the environment both during manufacturing and transport. These...

The hydrological basin of Keritis in Chania, Greece is mainly an agricultural area where various agrochemicals are used. In topsoils, the total and available forms of Cu, Zn, Pb and Cr were determined after their extraction with boiling Aqua Regia and DTPA respectively. Although the total heavy...

More than 73% of the electrical power requirements of Greece are generated in lignite-fired power plants. Greece is the thirteenth largest coal and the fifth largest lignite producer in the world. The lack of domestic high-rank coals makes necessary to use low quality lignite for power generation in...

The leachability of Pb2+ from natural greek clinoptilolite was investigated according to the standard procedures TCLP/EPA/RCRA (1311), EPA Methods 1310, 1320 and DIN 38414-S4. Through SEM/EDAX analysis it was shown that lead was uniformly loaded onto the particles subjected to acid treatment...
