“…A similar trend was reported in Zhu et al (2015) with MDA content of V. natans first increased and then declined with the increase of the ammonia concentration. In contrast, several researchers (Huang et al 2013;Wang et al 2016) observed the decrease of MDA content at lower concentrations of ammonia while significant increase of MDA content at high ammonia concentrations. It seems that the ammonia stress to MDA content in submerged plants was species specific.…”

The stress tolerance of wetland plants is crucial for their appropriate application in constructed wetland (CW). Ammonia, one of the major pollutants in wastewater, is nutrition for plants at low concentrations but could be toxic at excess concentrations. This study aimed to investigate the effect of external ammonia at different concentrations (0, 1, 2, 4, 8, 10 mg L −1 ) to a specific submerged plant Potamogeton crispus (P. crispus), which has been used widely in CW. Results showed that the threshold value of ammonia for P. crispus was 4 mg L −1 , under which no obvious variations from the control group were detected in all associated observations. When ammonia concentration exceeded 4 mg L −1 , plants displayed significant increase in lipid peroxidation product contents (MDA, O 2 − and H 2 O 2 ), antioxidant enzyme activities (T-SOD, POD, and CAT), and a corresponding increase in the percentages of electrolyte leakage. However, external ammonia only had slight effect on the chlorophyll synthesis of P. crispus under the studied concentration range. Excess ammonia exposure (≥4 mg L −1 ) could affect the physiological responses of P. crispus, by inducing oxidative stress and by limitedly altering permeability of cell membrane and plant photosynthesis. The results of this study supplied useful information for the aquatic vegetation collocation in CW design, and it is suggested to take proper application of P. crispus in CW when treating eutrophication or other relatively heavily polluted water.

“…As comparison to the present results, Muradov et al (2014) reported that the removal efficiency for duckweed and azolla plant was 54.9% and 43.0%, respectively. Huang et al (2013), Zhang et al (2014) and Wang et al (2014) reported that the aquatic plant (Lemna minor) takes up NH 4 + readily and grows well at concentrations of the ion of up to 84 mg/l, it takes up NH 4 + and NO 3 through both roots and the lower surface of the fronds, and may prefer NH4+ to NO 3 (Fang et al 2007). Nevertheless, the higher NH4 + concentrations still lead to growth rate reduction and photosynthetic pigment loss.…”

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.

Industrial production of poultry meat is associated with indirect environmental impacts such as contributing to climate change and deforestation and other direct impacts such as the deterioration of the quality of surface waters. Poultry industry effluents are rich in organic matter, nitrogen, and phosphorus; nutrients can be removed from wastewater through the use of macrophytes and periphyton. An essay in mesocosms with poultry industry wastewater recirculation was developed in the presence and absence of a native macrophyte Spirodela intermedia and periphyton from a lowland stream (La Choza stream, Buenos Aires) where the effluent is poured. The diffusion of O 2 , increased by water recirculation, had the effect of increasing the concentration of dissolved oxygen in wastewater. The presence of S. intermedia and algae periphyton significantly contributed to the removal rates (%) of solids (69.7 ± 3.9), ammonium nitrogen (84.0 ± 3.4), and total phosphorus (38.1 ± 1.8) from residual water and favored nitrification. The dominance of Bacillariophyceae on other groups of algae of periphyton and the low representation of Euglenophyceae indicated an advanced stage of the effluent treatment process at the end of the assay.
