“…However, subsequent accumulation along the food chain is a potential threat to human health. Swain et al (2014) recorded a similar trend (root>leaves>stem) of bioaccumulation of Cd in an experiment on the phytoremediation of Cu and Cd from water using E. crassipes. Also, Soltan and Rashed (2003) concluded that water hyacinth accumulated higher concentrations of heavy metals in the roots than in the aerial parts when the plant was treated with several heavy metals (Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn).…”

In this study the accumulation of Iron (Fe), Zinc (Zn), Cobalt (Co), Chromium (Cr), Cadmium (Cd), Lead (Pb) and Nickel (Ni) in sediment, water, some fish samples (Schilbe mystus, Mormyrus rume, Gymnarchus niloticus, Cynoglossus senegalensis, and Chrysichthys nigrodigitatus) and an aquatic plant Eichhornea crassipes collected from Lekki lagoon, Lagos Nigeria were examined. Heavy metals in the water, sediment, some selected fish and an aquatic plant were determined seasonally across nine sampling Stations; in the gills, liver and muscles of the fish species and in the root stem and leaves of Eichhornea crassipes using an atomic absorption spectrometer (AAS). Heavy metals concentrations in the sediment and water varied significantly, both spatially and seasonally. Metal concentrations varied between species and body parts while Co, Cr and Pb were not detected. Ni was found in the liver and gills of S. mystus and M. rume and Cr in the gills of G. niloticus only. In Eichhornea crassipes, metals detected were in the order: root>leaves>stem for Fe, Zn, Cr, and Cd; root>stem>leaves for Pb and Ni while Co was not detected. Heavy metal presence in Lekki Lagoon calls for monitoring of activities within and around the lagoon and policy development towards the sustainable ecosystem health services.

“…These equations showed that bioaccumulation rate or ability was inversely related to ion concentration (Table 6), as mentioned by many researchers [25]. On the other hand, the most effective phytoremediation takes place in low concentrations, because when high coefficient absorption for soil and plant was shown in this range, groundwater was more protected.…”

Heavy metals are a significant problem in municipal wastewater, in soil accumulation and are costly to remove in order to facilitate water use in irrigation. Wastewater, with three heavy metal cations and an anion, was employed in irrigation during the Sorghum bicolor (L.) Moench growth period. Results show that the absorption coefficient or bioaccumulation ability of Sorghum bicolor (L.) Moench is relegated to certain heavy metals and their concentrations, but not at all to plant tissues in dry ash weight (DAW) scale. Heavy metals absorption was determined in the following order: cadmium = lead > arsenic, and while tissue accumulation based on DAW was equal for cadmium and lead, based on dry weight (DW) all three ions differed. The soil's ability to accumulate heavy metal ranked as follows: cadmium > lead > arsenic by wastewater quality in this experimvent. These results change many previous ideas about decreasing the transportation of heavy metals from root to shoot or other organs in plants. With low cadmium and lead concentration in irrigation, sorghum is a good plant for remediation; however, in high concentration this plant benefits from arsenic remediation. Soil is a critical parameter for wastewater phytoremediation. This topic merits further research.Heavy metal hyper accumulating plants can absorb and accumulate high levels of toxic ions in their tissues, and then can be used as toxic ion remediators. Plants vary in their ability to detoxify different ions in heavy metals from soil and water, so that each hyper accumulator plant may accumulate any heavy metal more than others and be more suitable for any heavy metal ion remediation [2].Plants used in phytoremediation may produce hazardous biomass with high levels of toxic material, rendering them unusable in food or livestock. Consequently, the selection of plants with high remediation ability and economic value is vital to phytoremediation.Sorghum is a core agricultural plant in tropical areas. It is the fifth most consumed cereal in the world, used as food, animal feed and biofuel [7]. Sorghum can grow through wastewater irrigation, and has many remediation properties in soil pollution [8].The aim of this research is to investigate the practical remediation ability of sorghum on heavy metal-polluted wastewater to improve an actual method for sewage usage. Material and Methods Culture conditions3-5 seeds of sorghum were cultivated in pots 30 cm high (15 kg) in 16 h light and 8 h dark photoperiods, at 28 o C and 18 o C, respectively. The pots were irrigated 3 times a week during a 12-week growth period. Soil analysisSoil samples were taken from all treated pots (100 gr), IntroductionWastewater is a new water resource for agriculture and green space. However, wastewater carries pollution of many types, such as heavy metals, synthetic materials and coliform bacteria. Heavy metals are not biodegradable in the environment. When accumulated in ecosystems, heavy metals are very harmful even if present in low concentrations [1].Soil's ability to accum...

The historical lakes of India are getting over burdened with the loads of pollution due to the rapid growth of small scale industries, nutrient enrichment and other anthropogenic activities. The high concentrations of metals in the water bodies, their entry into ecological food chain and the resulting health effects are of great concern to the researchers in the areas of ecology. Due to the problems associated with the conventional methods of pollutant removal, phytoremediation method is gaining more attention. The plants to be used in this technique, it must have high capacity of metal absorption, its accumulation and reduction in the time of decontamination in an ecosystem. It is an environment friendly and cost beneficial technique for the removal of toxicants from the environment. This article present over view on status of heavy metal pollution in lake and remediation through plants in Indian context may helpful to researcher not only in India but around the world also. This base line data can help governmental and non-governmental organization for the management of water pollution.
