Every year, important quantities of winemaking waste create problems for wine producers. These arise from the difficulty disposing grape marc, which can pollute environment and affect nearby agricultural crops. The present research proposes a new direction valorization this agri-food in residual water depollution. Four biomaterials obtained were tested Pb removal: raw Merlot marc (MR), Sauvigno...

BACKGROUND The expanding number of patients treated with pacing, especially resynchronisation therapy and pacing system upgrades as well as leads remaining inactive, and prolonged life expectancy are the causes of an increase of the number of electrodes in pacemaker patients. The growing problem with endocardial lead infections and excess leads has made percutaneous lead removal technology wide...

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: 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...

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...

Membrane technology is one of the few non-pollutant choices when selecting a treatment process. A membrane with suitable pore size can remove almost all pollutants without using any chemicals. In this research, chromium, zinc and lead were removed from synthetic wastewater by a membrane bioreactor. The results showed that by using a membrane bioreactor, the COD removal efficiency was increased ...

INTRODUCTION AND OBJECTIVES The rate of implanted cardiac electronic devices is increasing as is the need to manage long-term complications. Lead removal is becoming an effective approach to treat such complications. We present our experience in lead removal using different approaches, analyzing the predictors of the use of mechanical extractors/surgical removal. METHODS Retrospective analysi...
