“…Typha species have been successfully used in phytoremediation strategies due to their growing ability in HM-polluted environments [ 1 , 53 ]. Their remarkable efficiency in removing metallic ions lie in their airy internal structure, comprised of tissues with open spaces, allowing better contaminant absorption [ 67 ].…”

“…Heavy metals (HMs) are chemicals used in many industrial processes, so their environmental levels have considerably increased, causing damage to living organisms. HM contamination is one of the most critical concerns due to its high persistence in the environment and its harmful effects on human health, plants, animals, and biodiversity [ 1 ]. So, physicochemical processes have been developed to remove HMs from polluted sites.…”

Heavy metal pollution is a severe concern worldwide, owing to its harmful effects on ecosystems. Phytoremediation has been applied to remove heavy metals from water, soils, and sediments by using plants and associated microorganisms to restore contaminated sites. The Typha genus is one of the most important genera used in phytoremediation strategies because of its rapid growth rate, high biomass production, and the accumulation of heavy metals in its roots. Plant growth-promoting rhizobacteria have attracted much attention because they exert biochemical activities that improve plant growth, tolerance, and the accumulation of heavy metals in plant tissues. Because of their beneficial effects on plants, some studies have identified bacterial communities associated with the roots of Typha species growing in the presence of heavy metals. This review describes in detail the phytoremediation process and highlights the application of Typha species. Then, it describes bacterial communities associated with roots of Typha growing in natural ecosystems and wetlands contaminated with heavy metals. Data indicated that bacteria from the phylum Proteobacteria are the primary colonizers of the rhizosphere and root-endosphere of Typha species growing in contaminated and non-contaminated environments. Proteobacteria include bacteria that can grow in different environments due to their ability to use various carbon sources. Some bacterial species exert biochemical activities that contribute to plant growth and tolerance to heavy metals and enhance phytoremediation.

“…The ability of some vegetables to remove and accumulate heavy metals may cause a serious health risk to human health when plants based food stuff are consumed (Wenzel et al,1999), but may also have the potential in the remediation (phytoremediation) of heavy metals contaminated soils. The tolerance characteristics of plants to heavy metal ions are diverse among the metal ions involved (Inouhe et al, 2012). Especially a group of metals called "Borderline class" metals including Mn, Zn, Fe, Ni, Cd, Pb and Cu etc.…”

“…Especially a group of metals called "Borderline class" metals including Mn, Zn, Fe, Ni, Cd, Pb and Cu etc. are capable of binding to multiple types of naturally occurring chemicals or components in plants, although "Class A" metals, such as K, Ca, Na, Mg, Al, and Cs prefer the O-donor ligands, all of which bind through oxygen, rather than the S or N bond ligands preferred by "Class B" metals (Inouhe et al, 2012).…”

“…Nevertheless, the tolerance against those toxic ions can be expressed in a highly specific manner for each metal in general in plants, and co-tolerance appears relatively rare (Inouhe 2005). One of the fundamental bases of the mechanisms can be addressed to either the alteration of the metal-sensitive metabolism and structure or the development of new metalsequestering principles within some cellular compartments (Inouhe et al, 2012). As for the latter detoxification mechanism, various types of metalbinding complexes have been identified from plants.…”

Vegetables are capable of taking up and accumulating heavy metals in their body. The concentrations of the metals increase as the soil available/background concentration increases as a result of human activities including discharge and dumping of industrial waste and effluents into environment. The aim of this review is to highlight the capability of the vegetables to take up and accumulate toxic heavy metals into their body as a result of industrial contami the water used for irrigation purpose and the impact of the metals on human and other organisms in the environment. For this review, available information on current publications, scientific journals, and articles were carefully used metals contaminated soil accumulate higher amounts of metals than those grown on uncontaminated soils, because in most cases, they absorb the metals through the root. Sometimes, metals may be incorporated with some essential elements required by plants in water and soil. Certain species classified as hyper accumulators are vegetables (mostly leafy vegetables like; spinach, lettuce, and cabbage. Some of the factors that affect metals uptake into plant ti includes; bioavailability, nature and type of the metal, environmental factors including pH and the plant itself, as some studies have shown some plants to have high uptake capacity than others. High concentrations of Pb, Zn, and Cu were reported for most instances, the background concentration of the heavy metals in the soil may not exceed the permissible limit, however, the vegetables have the ability to absorb and accumulate the metals even above the permissible limit. These heavy metals are toxic and pose serious effect on human health and other organisms in the environment. Conclusively, vegetables plays an important role in the body because they provides some essential nutrients to the body as such, any con can pose a serious health threat. Moreover, prolonged exposure and consumption of these contaminated vegetables may lead cancer and death.
