• No acute toxicity of silica-zirconia core–shell NP was found for D. magna and rerio . Retention Zr from the form ZrO 2 in both species. The same concentration molecular (ZrOCl ) did not result elevation fish tissue. environmental risk is higher than form. Trace element homeostasis, growth survival were affected by SiO @ZrO exposition. Model experiments under laboratory conditions carried out ...

Organochlorine pesticides such as DDT and HCH had been abundantly produced and used since the around twentieth century in all over the world and environmental pollution, food contamination and human body pollution had developed into social problem because of their high bioconcentration potential and high persistency. The use and manufacturing of DDT and HCH were forbidden in many countries incl...

. The metal bioaccumulation potential of selected macroalgae species as different pH ranges were study for usage as part of a possible secondary passive AMD treatment technology in algae ponds in temperate regions during winter months. . Two separate studies were conducted to determine the suitability of macroalgae for passive treatment when metabolic processes in macrophytes and microrganisms ...

the aim of present study was to investigate phytoremediation potential of puccinellia distans (jacq) parl using edta and dtpa and method of decreasing cd- chelating leacing risk. the soil samples spiked with cdcl2. the treatments comprised the following dosages 2.5dtpa, 5dtpa, 2.5edta, 5edta, 2.5edta+2.5dtpa, 2.5edta+5dtpa, 5edta+2.5dtpa, 5edta+5dtpa and control pots were not treated with edta ...
