A stand of five conifers (Pinus sp.) bordering a gasoline service station was studied to estimate the methyl tert-butyl ether (MTBE) emission rate from gasoline-impacted groundwater. Groundwater was impacted with gasoline oxygenates MTBE and tert-butyl alcohol (TBA) at combined concentrations exceeding 200,000 microg/L. Condensate from trees was collected in sealed environmental chambers and an...

Soil contamination with toxic metals resulting from global industrialization is a serious environmental issue. Industrial activities such as mining of ore, discharge wastewater, excess application fertilizer and pesticide have led to environment heavy cadmium, lead, mercury, copper, arsenic, zinc etc. Complete degradation not possible thus they continuously accumulate in the leading great threa...

Abstract Toxic metal contamination of soil is a major environmental hazard. Chemical methods for heavy metal's (HMs) decontamination such as heat treatment, electroremediation, replacement, precipitation and chemical leaching are generally very costly not be applicable to agricultural lands. However, many strategies being used restore polluted environments. Among these, phytoremediation promisi...

Phytoremediation, a plant based green technology, has received increasing attention after the discovery of hyperaccumulating plants which are able to accumulate, translocate, and concentrate high amount of certain toxic elements in their above-ground/harvestable parts. Phytoremediation includes several processes namely, phytoextraction, phytodegradation, rhizofiltration, phytostabilization and ...

Selenium (Se) is an essential trace element for humans and animals but at high concentrations, Se becomes toxic to organisms due to Se replacing sulfur in proteins. Selenium biofortification is an agricultural process that increases the accumulation of Se in crops, through plant breeding, genetic engineering, or use of Se fertilizers. Selenium phytoremediation is a green biotechnology to clean ...

Abstract This paper reviews plants and microorganisms removal of heavy metals from contaminated sites through bioaccumulation. Increased industrial activities have led to the uncontrolled release into environment, resulting in a global increase metal pollution. Heavy are also consumed surface glasses over prolonged period use. pollution is serious problem that can wide-ranging long-lasting impa...

Water pollution due to heavy metals has become a serious environmental concern their hazardous properties. Since conventional water remediation techniques are generally ineffective and non-environmentally friendly, phytoremediation gained increasing attention from worldwide researchers scientists its cost-effectiveness friendliness. Hence, this review first discussed soil remediations. Phytorem...

Toxic substances have a deleterious effect on biological systems if accrued in ecosystems beyond their acceptable limit. A natural ecosystem can become contaminated due to the excessive release of toxic by various anthropogenic and activities, which necessitates rehabilitation environmental contamination. Phytoremediation is an eco-friendly cost-efficient method biotechnological mitigation for ...

Lack of nutritive and consumption polluted food sources are the main health implications in African countries. Vegetable production is an optional balanced source easily grown urban rural areas. However, levels contaminant heavy metals cultivated vegetables have not yet been identified. This review scrutinizes contamination route, sources, effects, environmental problems, safety complications, ...

introduction the lead is considered as one of the most toxic heavy metals in environment organizations of industrial and developing countries. therefore, refining of soil and water contaminated to this element is from most important environmental policies of this countries. lead metal is unnecessary for the body, so that trace amount in the body, indicating contamination with this element. lead...
