“…These changes may also reflect less water pollution due to the phytoremediation. Some researchers showed that the major outcome of nitrite poisoning is the oxidation of hemoglobin to methemoglobin in erythrocytes (González et al, 2000;Svobodova et al, 2005;Kroupovaa et al, 2008). Consequently blood oxygen transport is compromised, since methemoglobin does not bind oxygen.…”

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.

“…Exposure to 7.8 mg NO − 2 -N L −1 resulted in gill lamellar thickening and epithelial lifting along with a proliferation of mucous cells for the greenlip abalone (Harris et al 1998). Data obtained by Gonzales et al (2000) suggest that environmentally realistic concentrations of nitrite may affect the dynamics of conjugative metabolism in fish. A review on the toxicity of nitrite to fish giving other effects of nitrite has been written by Lewis and Morris (1986).…”

Literature frequently mentions increased nitrite concentrations along with its inhibitory effect towards bacteria and aquatic life. Nitrite accumulation has been studied for decades, and although numerous causal factors have already been commented on in literature, the mechanism of nitrite accumulation is not always clear. From the broad range of parameters and environmental factors reviewed in this paper, it is obvious that the causes and consequences of nitrite accumulation are not yet completely understood. Among others, pH, dissolved oxygen, volatile fatty acids, phosphate and reactor operation have been found to play a role in nitrite accumulation, which results from differential inhibition or disruption of the linkage of the different steps in both nitrification and denitrification. In the case of nitrification, this differential inhibition could lead to the displacement or unlinking of the ammonia oxidisers and nitrite oxidisers. In this paper, the idea is formulated that the nitrifier population forms a role model for the total microbial community. Increased nitrite concentrations would in this aspect not only signal a disruption of nitrifiers, but possibly also of the total configuration of the microbial community.Abbreviations: AMO -Ammonia mono-oxygenase; Anammox -Anaerobic ammonium oxidation; AOBAmmonia-oxidising bacteria; ATP -Adenosine triphosphate; COD -Chemical oxygen demand; DNRA -Dissimilatory nitrate reduction to ammonium; DO -Dissolved oxygen; EU -European union; FA -Free ammonia; F/M -Food to micro-organism ratio; FNA -Free nitrous acid; HAO -Hydroxylamine oxidoreductase; HRTHydraulic residence time; NDBEPR -Enhanced biological phosphate removal with nitrification and denitrification; NO -Nitric oxide; NOB -Nitrite-oxidising bacteria; NOR -Nitrite oxidoreductase; OLAND -Oxygen limited autotrophic nitrification denitrification; RBC -Rotating biological contactor; Sharon -Single reactor high activity ammonia removal over nitrite; SRT -Sludge residence time; TAN -Total ammoniacal nitrogen; TOC -Total organic carbon; VAS -Volatile attached solids
