Wetland pollution is responsible for dangerous hazards that affect developing and developed countries. Industrialization and production of chemical compounds led to worldwide deterioration of the environmental quality (Chakravarty et al. 2010). The contamination of the aquatic ecosystems with metals is a worldwide and local problem. Trace metals are toxic when present in excess concentrations. These metals can accumulate along the food chain, because of their solubility and mobility (Yan et al. 2010). This eventually leads to serious health and ecological hazards. Wetlands are natural filters for the reduction of pollutants transported by water in water bodies and thus they are considered as effective, low-cost, cleanup option to improve the quality of surface waters. It was reported by many investigators that the vegetation covering the wetland areas and the associated microorganisms plays an important role in sequestering large quantities of nutrients and metals (e.g. Cronk and Fennessy 2001; Eid et al. 2012; Galal and Shehata 2014). Analyzing water, sediments, macrophytes and animals can determine trace metal…show more content…
Continuous monitoring of the metal concentrations in soils, waters and plants is essential to know the levels and strategies to minimize contamination to reduce risks to human health (Lente et al. 2014). There has been an increasing interest in the use of green plants to remove or at least immobilize metals in a process known as phytoremediation (Peng et al. 2008). One method of this technology is phytostabilization, where plants are used to immobilize metals and store them in their below-ground organs and/or soil. , Hyperaccumulators may be used to remove metals from the soil during the phytoextraction and concentrate them in the above-ground organs (Galal and Shehata
