Keywords: Oreochromis niloticusPhytoremediation Ceratophyllum demersum Lemna minorAquaculture Wastewater Pollution Two aquatic macrophytes, Ceratophyllum demersum and Lemna minor, were used in aquaculture wastewater treatment. Tilapia fish (Oreochromis niloticus) with total body weight of 50-60 g were placed in 60 L aquaria. Four treatment groups were included: control (no plant treatment, depended on artificial filtering for purification), Lemna minor (Lm), Ceratophyllum demersum (Cd), and mixed plants group (Lm+Cd). Each group had three replicates (5 fish/replicate). The experiment was conducted for 4 weeks. Physicochemical parameters of aquaculture wastewater including pH, total dissolved solids (TDS), conductivity, turbidity, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), total phosphorous (TPO 4 ), nitrate (NO 3 ), nitrite (NO 2 ), and ammonia were determined. The results reflected more effective removal of pollutants from fish aquaria by both plants than that by the artificial aeration/filtering. The effectiveness of pollution removal was higher in Cd group > Lm > Lm+Cd, compared to the control. This order of phytoremediation was confirmed by improvements in tilapia fish health status including liver function (AST, ALT, albumin), kidney function (creatinine, urea, uric acid), in addition to other nutritional and hematological parameters. It could be concluded that the phytoremediation using C. demersum is ecofriendly and effective in removing contaminants from Tilapia aquaculture wastewater and therefore, it is recommended to be applied in tilapia farms.

“…Kashim and Singh (2002) reported that due to increase of pH, there was an increase in the uptake of elements. This is the reason that initially relative growth rate of treated plants significantly increased with the passage of time (Saha et al, 2015).…”

“…The essential elements of this study are Mg and and Zn (micronutrients) which possess higher BCF value for both roots and shoots and in TrF. This is due to the ability of plants to uptake essential elements compared to non-essential elements also plants may develop tolerance strategies that reduce their uptake and accumulation (Saha et al, 2015;Sarathambal et al, 2017;Sung, Lee and Munster, 2015). Plants which are possessing < 1 for TF and BCF values are considered to be unsuitable for phytoextraction process (Romanova, Shuvaeva and Belchenko, 2016;Romero-Hernández et al, 2017).…”

“…Plants which are possessing < 1 for TF and BCF values are considered to be unsuitable for phytoextraction process (Romanova, Shuvaeva and Belchenko, 2016;Romero-Hernández et al, 2017). Results indicate that the root parts of the plant possess high concentration of metal ions which indicates a higher accumulation of ions to protect photosynthetic tissue in the above ground parts (Saha, Banerjee and Sarkar, 2015;Salama, Al Watban and Al-Fughom, 2011). High concentration of metal ions in the root indicates that element compartmentalization, tolerance strategy by the plant in respect to the different metal ions and the level of concentration (Hazra et al, 2015;Zengin and Munzuroglu, 2005).…”

The present study aimed to investigate the bioaccumulation of heavy metals from the effluent of battery industry by an aquatic plant, Bacopa monnieri. Experiment was carried for 25 days and heavy metal concentrations were analyzed in plant parts (roots and shoots), soil and effluent using atomic absorption spectroscopy (AAS) for 5 days each. Parameters such as Translocation Factor (TF), Bioconcentration Factor (BCF) and Transposition Factor (TrF) were calculated to analyze heavy metal interaction between plant, soil and effluents. Zn and Mg were found to be high in TF, BCF and TrF, but Cr had a TF value higher than Zn as it translocates high amount of ions to plant parts. TrF values of contaminants increased constantly in the following order: Mg > Zn > Cd > Pb > Cr. TF and BCF values were not > 1 for toxic metals (Pb, Cr and Cd). B. Monnieri can be used as a phytoextractor in removing contaminants from aquatic bodies.

“…They can grow naturally on calm waterways like abandoned rivers, canals and ponds [39]. Both of these plants are also able to absorb heavy metals found in wastewater [40][41]. This study aims to determine the tolerance and survival of these two plants (A. pinnata and L. minor) in treated POME as to select the right concentrations of POME to be used in the next stage of plant uptake in larger scale (pilot scale) by these plants in treated POME.…”

The phytotoxicity of Azolla pinnata and Lemna minor was assessed when exposed To Treated Palm Oil Mill Effluent (POME) for their survival and growth tolerance in a 5-day exposure conducted in an open laboratory at Universiti Kebangsaan Malaysia. A total of 34 100 mL-containers were used, with three replicates for each concentration, including plant less control and plant control. 50 mL of treated POME in different concentrations (100%, 75%, 50% and 25%) was filled in each container and exposed to 3 g Azolla pinnata or Lemna minor with observation conducted daily. After two days of exposure, 40% of A. pinnata died in 100% concentration and almost 100% died after 5 days of exposure for all concentrations. On L. minor, only 5% mortality was observed for 100% concentration on the fourth day and remained healthy until the end of five days. At the end of 5-day phytotoxicity exposure, the highest removals were 63.0%, 70.5%, 51.0%, 65.4% and 53.8% respectively for COD, BOD, Ammonia, Phosphate And Nitrates by A. pinnata, while the maximum removals recorded by L. minor were 61.0%, 54.0%, 9.8%, 61.4% and 31.6% respectively, giving evidence that A. pinnata is more effective in removing pollutants than L. minor although its survival in the treated POME is lesser than L. minor.
