Phytotechnologies are rapidly replacing conventional ex-situ remediation techniques as they have the added benefit of restoring aesthetic value, important in the reclamation of mine sites. Alders are pioneer species that can tolerate and proliferate in nutrient-poor, contaminated environments, largely due to symbiotic root associations with the N2-fixing bacteria, Frankia and ectomycorrhizal (E...

The effect of the glass industry on heavy metal characterization was assessed in the sludge/sediments of 5 discharge pits (sites) for effluents of functional glass factories and/or finishing workshops in the study area. A comprehensive profile of Zn, Mn, Co, Cd, Pb, Cr, Ni,Cu and As levels in industrial sludge was obtained. Correlation coefficients for metal pairs indicate varying levels (posit...

Phytoextraction relies on plants with a high capacity to absorb heavy metals and remove them from the soil. The objective of this study was to analyze the potential of sunflower (Helianthus annuus L.) and white mustard (Sinapis alba L.) for phytoextraction of Zn-contaminated soil. Research was based on a strict pot experiment conducted in a greenhouse. Seven treatments were established with inc...

Chromium is a reactive and toxic heavy metal that enters the soil through various anthropogenic activities moves food chain affecting adversely higher trophic levels including humans. While engineering techniques to remediate contaminated sites are costly energy intensive, phytoremediation with suitable plant species low cost, easy eco-friendly technique, which uses solar in process. Using non-...

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, ...
