BACKGROUND Developing methods for protecting organisms in metal-polluted environments is contingent upon our understanding of cellular detoxification mechanisms. In this regard, half-molecule ATP-binding cassette (ABC) transporters of the HMT-1 subfamily are required for cadmium (Cd) detoxification. HMTs have conserved structural architecture that distinguishes them from other ABC transporters ...

Heavy metal pollution all around the world has become a major environmental concern and the bioremediation of polluted environments is an increasingly popular strategy due to both its efficiency and safety. In this study, a bacterial strain resistant to heavy metal was isolated from metal contaminated sites. Strain MKH2 was removed Pb (II) with 95.06%. This isolate was also resistant to zinc, c...

Mercury naturally occurs in gas and oil deposits a wide range of concentrations covering six orders magnitude: up to 5 mg/m 3 natural 600 ppm (mg/kg) crude oil. hydrocarbons poses number technological environmental problems: contamination equipment products with this extremely toxic element, poisoning catalysts, initiates intensive corrosion equipment, thereby enhancing accident risk. Metal mer...

this study at first level focused on definitions and descriptions of  some landfills and landfills sites all around the world and  survey on how important they are for regional governments and responsible in duty  as a very important responsibility for locals and their health. at the second level we had a look on heavy metals concentration which are by many definitions as follows: lead, nickel,...

The increasing level of anthropogenic environmental pollution and effective means to reduce the negative impact xenobiotics on animal human health is an urgent problem today. Considering this, purpose study examine effect heavy metals accumulation processes under poisoning conditions, biochemical parameters in body rats. Analogue groups were formed rats same age, gender, weight conduct study. R...

Background: Toxic alcohol poisonings are responsible for high mortality and morbidity in Russia. This study was aimed to evaluate the trends of harmful ethanol (EtOH) drinking as well as methanol (MeOH), isopropanol (IPA) and ethylene glycol (EG) poisonings in the Middle Urals region of Russia. Methods: In this retrospective study, the medical records of patients poisoned with MeOH, IPA and EG ...

BACKGROUND Chelation therapy involving organic chelators for treatment of heavy metal intoxication can cause cardiac arrest, kidney overload, mineral deficiency, and anemia. METHODS In this study, superparamagnetic iron oxide nanoparticles (SPIONs) modified with an edible biopolymer poly(γ-glutamic acid) (PGA) were synthesized by coprecipitation method, characterized and evaluated for their r...

Introduction Poisoning ofwildlife is a wide spread and major investigational, problem for wildlife law enforcement officers. Protected wildlife killed through pesticide misuse or environmental contamination is just as dead as if they were illegally killed with a gun. The impact on the population may, in fact, be greater because of secondary and even tertiary poisoning or impacts on breeding pot...
