Removal of persistent organic pollutants from landfill leachates treated in three constructed wetland systems
The objective of the study was assessment of occurrence and removal of two groups of persistent organic pollutants: polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in landfill leachate (LL) treated in three constructed wetland systems (CWs) of different construction and flow regime. Two subsurface flow systems (SSF) were analyzed: one with horizontal flow and the ...

Mathematical modelling of sediment chemicophysical parameters in a coastal lagoon to estimate high density seagrass meadow (Ruppia cirrhosa) distribution
In spring 2003, the pH, redox potential (Eh), grain-size (G), Total Nitrogen (TN), Total Phosphorus (TP) and Total Organic Carbon (TOC) were measured in superficial sediment samples from 83 sampling stations equally and randomly distributed inside the Orbetello lagoon. Localisation of the seagrass meadows (Ruppia cirrhosa) and the estimation of biomasses were carried out at the same time. A ...

Cytotoxic and genotoxic activities of waters and sediments from highway and parking lot runoffs
The genotoxicity of water and sediment samples from stormwater treatment systems and water from urban highway runoff was tested in the Salmonella/microsome assays with Salmonella typhimurium, micronucleus assay (Trad-MN) with plants and with human-derived liver cells (HepG2), or comet assay with HepG2. Cytotoxicity of water samples was studied using either reactive oxygen species (ROS) ...

Assessment of arsenic and vanadium pollution in surface sediments of the Egyptian Mediterranean coast
An assessment of arsenic and vanadium pollution was investigated for surface sediments collected from 41 sampling stations along the Egyptian Mediterranean coast during summer 2008. Grain size analysis, Total Organic Carbon (TOC), total silicate and carbonate contents were also studied. Concentrations of arsenic and vanadium were high especially in sediment samples collected from the eastern area ...
