in this study, cadmium (cd) accumulation was studied in an experimental aquatic exposure. mosquitofish (gambusia affinis) were acutely exposed for 96 h to a high concentration of cd (12 mg/l) and were chronically exposed to a low concentration of cd(0.4 mg/l) for 30 days. cd accumulation profiles differed between the two cd exposures. the cd concentation in g. affinis tissues increased linearly...

Background: Cadmium (Cd) is a heavy metal that has widespread use. It enters the food chain in different ways, including soil and water. Cadmium can cause dysfunction of different body organs. Zinc (Zn) and magnesium (Mg) supplementation can have protective effects against cadmium toxicity due to their antagonistic and antioxidants properties. This study examines the influence of supplemental...

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 ...

The use of low molecular weight organic acids (LMWOAs) for the phytoremediation heavy metals has become a promising technique. We chose five kinds (oxalic acid (OA), acetic (AA), tartaric (TA), malic (MA), and citric (CA)) with six application rates (1, 2, 3, 4, 5, 6 mmol/kg) planted sunflowers (Helianthus annuus L.) in Cd-polluted soil to study efficiency Cd degree toxicity plants. Treatment n...

environmental pollution by heavy metals is a growing global concern. most heavy metals accumulate in the top soil and in the long term, increased concentrations in the soil results in increased absorption and accumulation in plants. the usual concentration of cadmium in the soil is 0.001-2.4 mg/kg of dry soil. the level of absorption and accumulation in plants depends on the type of plant, tiss...
