Groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. This study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...

lead poisoning associated to residuals of batteries recycling was diagnosed in a small herd of holstein cattle. in this outbreak, 10 animals showed clinical signs of lead poisoning, 5 dead and others saved after chelating therapy with cana2edta.mean blood lead level of clinically intoxicated cattle was 0.624 ± 0.388 ppm and the levels varied between 0.320 and 1.300 ppm. blood and milk lead leve...

background this study demonstrates the removal efficiency of phenol from aqueous solutions by electrocoagulation process using aluminum electrodes and also investigates solution chemistry and polymeric natural organic matters on removal efficiency objectives: the main aim of this work was to focus on the removal of phenol by electrocoagulation process using aluminum electrodes. materials and me...

background: industrial development has caused the release of various pollutants including heavy metals into the environment. these toxic compounds are extremely dangerous to living beings and the environment due to their non-biodegradability, severe toxicity, carcinogenicity, the ability to be accumulated in nature and the ability to contaminate groundwater and surface water. the aim of the pre...

in this study, a bacterial species which could remove lead from wastewater was isolated from lead contaminated soil prepared in the laboratory. based on the biochemical and morphological characterization the bacteria were identified as brevundimonas vesicularis. the biosorption potentiel of powdered dry biomass of b. vesicularis was investigated by batch adsorption experiments. it was found tha...
