“…Aquatic plants are mostly used in the wastewater purification system of constructed wetland, because aquatic plants will take away a large amount of N, P, and other elements in the water during their growth (Li et al, 2015;Rocio et al, 2018). The results of this study showed that C. dactylon 'Tifton 85' had the strongest and fastest purification ability to purify eutrophic water.…”

A static experiment in greenhouse was conducted to investigate the growth of three grasses in high and medium eutrophic water and the effects of their removal on ammonia nitrogen (NH4+-N), nitrate nitrogen (NO3−-N), total nitrogen (TN), total phosphorus (TP), and the chemical oxygen demand (COD), and compared with cattail (Typha angustifolia). The results showed that 1) the removal efficiency of NH4+-N, NO3−-N, TN, TP, and COD treated by the four plants in eutrophic water were significantly higher than that in non-plant water. With the extension of treatment time, the concentrations of NH4+-N, NO3−-N, TN, TP, and COD in the eutrophic water decreased first and then tend to be stable. 2) Cynodon dactylon ‘Tifton 85’ (C. dactylon ‘Tifton 85’), Cortaderia selloana ‘Pumila’ (C. selloana ‘Pumila’) and T. angustifolia absorbed more than 95.7% and 88.6% of TN and TP in eutrophic water, and accumulate more than 89.5% and 82.0% in plants, respectively. However, the ratio of Cortaderia selloana ‘Silver Comet’ (C. selloana ‘Silver Comet’) was significantly lower. 3) The high abilities of these three plants to purify eutrophic water may be directly related to their rapid growth. 4) The comprehensive purification ability of the four plants to eutrophic was significantly different, in the order of C. dactylon ‘Tifton 85’ > C. selloana ‘Pumila’ ≈ T. angustifolia > C. selloana ‘Silver Comet’. These results indicated that C. dactylon ‘Tifton 85’ and C. selloana ‘Pumila’ can be used as alternative plants to T. angustifolia for the purification of eutrophic water. The results of this study can provide new materials and ideas for phytoremediation.

“…Comparable results have been obtained by Abd-Elaal et al [ 6 ] in Echinochloa pyramidalis and Ludwigia stolonifera with removal percentages of heavy metals (Pb, Cd, and Ni) between 77 and 95% in 10-day incubation period. This may be attributed to the fact that most of the active sites are occupied by toxic metal from surrounding media [ 19 ]. In this study, an increase of metal removal and accumulation was observed in a time dependent manner.…”

“…Drought, intensity of illumination, low or high temperature, salinity, UV radiation, ozone, and heavy metals are all stimuli that the antioxidant system can use to decide a plant’s resistance and tolerance too [ 19 ]. To eliminate ROS, plants have a system of enzymatic and non-enzymatic antioxidants [ 38 ], with the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) playing crucial roles [ 5 , 16 ].…”

A laboratory experiment was led to examine the lead bioaccumulation capacity of Ludwigia stolonifera (Guill. & Perr.) exposed to various Pb concentrations (0, 10, 25, 50, and 100 mg/L) for 1, 3, 5, and 7 days. The lead accumulation increased as the metal concentrations in the solution increased and over time, to an extreme accretion of 6840 mg/kg DW(dry weight) at 100 mg/L of lead on the 10 days exposure. The proportion removal efficiency, translocation factor, and bioconcentration factor of the plant were assessed. The maximum bioconcentration factor values (1981.13) indicate that the plant was a Pb hyperaccumulator, and translocation factor values (1.85), which are >1, indicate fit of L. stolonifera for eliminating Pb in Pb-contaminated water. Photosynthetic pigments were decreased with increase of Pb concentration and time exposure. Total chlorophyll content and Chl a/b ratio lowered to between 46 and 62% at 100 mg/L Pb after 10 days exposure. Protein content and soluble carbohydrate indicated a similar trend, which showed the highest decrease (7.26 and 36.2 mg/g FW(fresh weight), respectively) at 100 mg/L of Pb after 10 days. The activity of the antioxidant enzymes superoxide dismutase, ascorbate, and peroxidase was increased significantly in comparison to the control. The results indicate that L. stolonifera is a newly recognized Pb hyperaccumulator (6840 mg/kg DW), but physiological status indicates that the plant is not tolerant to high Pb concentrations.

“…The wastewater is released into drainage system without treatment, eventually, this toxic wastewater makes it way into River Kaduna which is the nearby water body (Bununu et al, 2015;Ogwueleka, 2014Ogwueleka, , 2015. Some of the wastewater can seep into aquifers and pollute underground water since they cannot be confined within specific boundaries (Braun et al, 2018;Demarco et al, 2018;Fernandez San Juan et al, 2018). The untreated wastewater tends to have an ecological impact on the nearby water bodies which is river Kaduna leading to increased nutrient load leading to eutrophication, which is open water can progressively lead to oxygen deficiency, algae blooms, and death of aquatic life.…”

The production of dye is usually associated with several intermediate products and waste which are usually toxic and bio-hazardous and often disturb the environmental equilibrium. The present study is aimed at selecting macrophytes with the highest efficiency in the remediation of wastewater generated from dyeing activities. The test macrophytes were introduce into three different troughs for each plant containing 100% wastewater, 50% wastewater and control (100% borehole water). After 21 days the macrophytes were removed for further analysis. The reduction efficiency, Heavy metal bioconcentration and bio translocation factor of the macrophytes was determined. The result obtained shows that the test macrophytes improved the pH but were not able to improve the color of the wastewater. Lemna minor have the highest reduction efficiency for BOD, COD, Oil, and Grease while Pistia stratiotes have the highest reduction efficiency for TDS and TSS, Eicchornia crassipes have the highest reduction efficiency for Cland Salvinia molesta have the highest reduction efficiency for phenol and ammonical Nitrogen. All macrophytes recorded high reduction efficiency for heavy metal removal but Pistia stratiotes and Eicchornia crassipes had the highest bioconcentration and translocation. These macrophytes should be introduced to the local dye users as a costless and environmentally friendly way of treating wastewater resulting from dyeing activity.
