The current study addressed the heavy metals accumulation potentials of seven perennial aquatic macrophytes (Cyperus alopecuroides, Echinochloa stagnina, Eichhornia crassipes, Ludwigia stolonifera, Phragmites australis, Ranunculus sceleratus and Typha domingensis) and the pollution status of three drains (Amar, El-Westany and Omar-Beck) in the Nile Delta of Egypt. Nine sites at each drain were sampled for sediment and plant analyses. Concentrations of eight metals (Fe, Cu, Zn, Mn, Co, Cd, Ni, and Pb) were determined in the sediment and the aboveground and belowground tissues of the selected macrophytes. Bioaccumulation factor (BF) and translocation factor (TF) were computed for each species. The sediment heavy metals concentrations of the three drains occurred in the following order: El-Westany > Amar > Omar-Beck. The concentrations of sediment heavy metals in the three drains were ordered as follows: Fe (438.45–615.17 mg kg−1) > Mn (341.22–481.09 mg kg−1) > Zn (245.08–383.19 mg kg−1) > Cu (205.41–289.56 mg kg−1) > Pb (31.49–97.73 mg kg−1) > Cd (13.97–55.99 mg kg−1) > Ni (14.36–39.34 mg kg−1) > Co (1.25–3.51 mg kg−1). The sediment exceeded the worldwide permissible ranges of Cu, Zn and Pb, but ranged within safe limits for Mn, Cd, Ni and Co. P. australis accumulated the highest concentrations of Fe, Co, Cd and Ni, while E. crassipes contained the highest concentrations of Cu, Zn, Mn, and Pb. Except for C. alopecuroides and Cu metal, the studied species had BF values greater than one for the investigated heavy metals. Nevertheless, the TFs of all species (except Cd in L. stolonifera) were less than one. Hence, the studied species are appropriate for accumulation, biomonitoring, and phytostabilization of the investigated metals.

Biomonitoring study of heavy metals was done at pilgrimage freshwater ecosystems of Central Gujarat, India, to ascertain the degree of 17 metals. The study focused on the assessment of available metals in Eichhornia crassipes (Mart.) Solms., collected from sacred palustrine habitat (Dakor Sacred Wetland – DSW) of Gujarat, to be used as a biomonitor (active) species, in comparison with sediment (abiotic monitor) for metal pollution. The results were obtained by analyzing elemental composition of rhizome, tuber, stem and leaves of native aquatic freshwater macrophyte (Eichhornia crassipes) along with bottom sediments for 17 heavy metals (Ti, Cr, Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, Y, Zr, Nb, Ba, Pb, Sm, Ir) using Wavelength Dispersive X-Ray Fluorescence (WD-XRF) (Omania Software). The highest concentrations were observed in rhizome (12) in assay species of aquatic macrophyte, followed by tuber and stem (10 each), and least content was observed in leaf (8). Toxic heavy metals (Ti, Mn, Fe, Zn, Br, Sr, Zr, Pb) were detected, prone to cardiac, respiratory, musculo-skeletal and hepatic interferences in indigenous human clusters in and around studied wetland. Eichhornia crassipes was proved to be the best phytoaccumaltor species for heavy metals, exhibited by highest translocation factor for Zn, Sr, Zr, and Pb, and bioaccumulation factor for Mn, Rb, Sr and Fe metals. Present research indicates that E. crassipes (Mart.) Solms. is better remediator species for mobility of Pb, Zr and Sr metals. Thus, Eichhornia crassipes can be used for an effective abatement of contaminated aquatic sites.

This study was aimed to assess the efficiency of N.oleander to remove heavy metals such as Copper (Cu) from wastewater. A toxicity test was conducted outdoor for 65-day to estimate the ability of N.oleander to tolerate Cu in synthetic wastewater. Based on a previous range-finding test, five concentrations were used in this test (0, 50, 100, 300, 510 mg/l). The results showed that maximum values of removal efficiency was found 99.9% on day-49 for the treatment 50 mg/l. Minimum removal efficiency was 94% day-65 for the treatment of 510 mg/l. Water concentration was within the permissible limits of river conservation and were 0.164 at day-35 for the 50 mg/l treatment, decreased thereafter until the end of the observation, and 0.12 at day-65 for the treatment 100 mg/l. the concentrations of water samples exceeded the permissible limits for 300 and 510 mg/l throughout the observation. Bioaccumulation factor (BAF) for N.oleaner was found to be greater than one for all the treatments. Higher translocation factor (TF) were 1.65, 1.73, 2.61 and 2.34 mg/l for 50, 100, 300 and 510 mg/l, respectively. This study revealed that N.oleander can tolerate and treat Cu concentration in wastewater.

Removal Of Heavy Metals

Pollution of the aquatic environment with toxic metals has been attracting considerable attention over the past decades and increasing urbanization, industrialization and overpopulation are the main cause. Due to this toxic pollutant the global water crisis is one of the most serious problems facing by the humanity today as also plants and animals are very sensitive to the presence of these toxic metals. Phytoextraction is the most cost effective and environment friendly way to solve the problem of heavy metal pollution by using plants. Macrophytes are important component of aquatic communities due to their roles in oxygen production, nutrient cycling, water quality control, sediment stabilization to provide habitat and shelter for aquatic life and also for being considered efficient heavy metal accumulators. The main route of heavy metal uptake is through their roots in emergent and surface floating plants whereas, leafy submerged plants uptake heavy metals both through roots and leaves. Roots of wetland plants play the primary role in wastewater purification followed by stems and leaves. Aquatic macrophytes therefore are very useful for the treatment of wastewater to mitigate variety of pollution level and now are the important research issues all over the world. In this review an effort has been made to summarize the role of aquatic macrophytes in the removal of heavy metals from the polluted water to improve the water quality.

Three aquatic macrophytes viz. Eichhornia crassipes, Pistia stratiotes and Lemna gibba were studied for their potential to remove heavy metals from Flashlight manufacturing industry effluent. Plants were exposed to 100%, 75%, 50%, 25% and 0% (distilled water) concentration of effluent for 5 weeks. Results revealed that the macrophytes under study were highly efficient in the removal of Hg, Mn, Zn and Pb. Translocation factor expressed that metals were largely retained in the roots of Pistia stratiotes and Lemna gibba while Eichhornia crassipes concentrated most of the metals in shoots. Analytical results showed that Eichhornia crassipes removed approximately 67.535, 89.30, 80.84 and 69.80% of Hg, Pb, Zn and Mn, respectively, from 100% concentrated effluent which shows its higher metals removal efficiency compared to Pistia stratiotes(65.44%, 87.109%, 70.23%, 63.242%) and Lemna gibba (71.84%, 89.074%, 70.97%, 73.97%,), respectively. These plants were also subjected to toxicity assessment and no symptoms of metal toxicity were found. Therefore, these macrophytes can be applied on the large scale treatment of waste water where volumes generated are very high and concentrations of pollutants are low.

Heavy metals accumulation from industrial wastewater even at low concentrations can cause long term cumulative health effects. To overcome this problem, phytoremediation is an alternative method to treat industrial wastewater. In this study, Ipomoea aquatica and Centella asiatica were used as phytoremediation plants for removing aluminum (Al) and iron (Fe) from industrial wastewater. The results showed that the regression value (R2) for all metal concentrations (mg/L) over treatment day is positive and similar to R2 = 1. This result indicated that the metal concentration exhibits a good relationship for reflecting the decrease in the metal concentration with the proportion of treatment day. It was found that I. aquatica accumulates higher Al and Fe contents than C. asiatica. The translocation factor of both plants was found to be greater than 1, implying that both plants can accumulate and extract heavy metals from industrial wastewater.

The present study deals with comparative evaluation of three different aquatic macrophytes, i.e. Myriophyllum spicatum, Sagittaria sagittifolia and Pistia stratiote planted at three different concentrations (1.0, 3.0 and 5.0 mg/L) of metals in laboratory experiment for Cd, Cu and Zn removal from aqueous solution. Result revealed high removal (>90%) of different metals during 15 days experiment. Highest removal was observed on 13th day of experiment, thereafter it decreased. Results revealed Pistia stratiote as the most efficient for the removal of selected heavy metal followed by Sagittaria sagittifolia and Myriophyllum spicatum. Selected plants can be used for large scale removal of Cd, Cu and Zn from waste water.
