Organic matter, nutrients, and chemicals are some of the waste materials found in most domestic wastewaters. The purpose of this research was to evaluate the potentials of Pistia stratiotes, Salvinia molesta, and Eichhornia crassipes aquatic weed plants in the tertiary treatment of secondary domestic wastewater using hydroponic systems. Physicochemical analysis that considered turbidity, phosphate, ammoniacal nitrogen, and nitrate was conducted on the wastewater samples at different retention times of 6, 12, and 24 h for 14 days. The best performance was observed for a 24 h retention treatment system, with up to 91% (P. stratiotes), 94% (S. molesta), and 89.3% (E. crassipes) reduction for turbidity; 81.2% (P. stratiotes), 82.7% (S. molesta), and 88.5% (E. crassipes) for phosphate reduction; 88.66% (P. stratiotes), 90.47% (S. molesta), and 89.11% (E. crassipes) for ammoniacal nitrogen reduction; 83.6% (P. stratiotes), 92.1% (S. molesta) and 93% (E. crassipes) for nitrate reduction. Hence, the application of hydroponic systems in cultivation of the macrophytes proved to be effective in the phytoremediation process by removing the residual nutrients present in the treated secondary domestic wastewater. Additionally, this method can be used for the cultivation of plant-based biomass and other non-edible useful crops using the free nutrients content of the wastewater before its discharge into the natural environment.

The lack of clean water sources, due to the presence of pollutants in water, is a major issue in many countries, including Malaysia. To overcome this problem, various methods have been introduced, including phytoremediation treatment. Therefore, this phytoremediation study examined the ability of five aquatic plants—Centella asiatica, Ipomoea aquatica, Salvinia molesta, Eichhornia crassipes, and Pistia stratiotes—to remove three pollutants—total suspended solids (TSS), ammoniacal nitrogen (NH3-N), and phosphate—from aquaculture wastewater. Using wastewater samples, each containing 50 g of one of the plants, the pollutant levels were measured every two days for 14 days. The results showed a drastic decline in the concentration of pollutants, where C. asiatica was able to remove 98% of NH3-N, 90% of TSS, and 64% of phosphate, while I. aquatica showed the potential to eliminate up to 73% of TSS and NH3-N, and 50% of phosphate. E. crassipes drastically removed 98% of phosphate, 96% of TSS, and 74% of NH3-N, while P. stratiotes was able to eliminate 98% of TSS, 78% of NH3-N, and 89% of phosphate. S. molesta was efficient in removing 89.3% of TSS and 88.6% of phosphate, but only removed 63.9% of NH3-N.

Research was conducted to quantify the level of copper (Cu), chromium (Cr), cadmium (Cd) and lead (Pb) contamination in battery industry effluent and to assess the remediation potential of three invasive aquatic macrophytes Eichhornia crassipes, Pistia stratiotes and Hydrocotyle umbellata by growing on industrial effluent collected from Lead acid Battery industry.The effluent was heavily contaminated with Pb (10mg/l) and sulphuric acid (pH 2- 2.1). Due to high Pb concentrations and low pH (2-2.2) the plants were unable to survive. Mortality rate of E. crassipes was 96 % while P. stratiotes and H. umbellata were 100% rotten. The experiment was repeated after adjusting the effluent pH to 7-7.5 to increase the plant life.Plant parts and wastewater samples were analyzed after every 3 days interval uptil 21st day. The amount of Cr, Cd and Cu in the effluent was 0.076 mg /L, 0.036 mg /L and 0.097 mg /L, which was in permissible limits of NEQs (1.0 mg/l, 0.1 mg/l and 1.0 mg/l) respectively. Pb was found 10 times higher i.e. 10 mg/l than the permissible limit 0.5 mg/l. E. crassipes removed Pb>Cr>Cu>Cd while P. stratiotes and H. umbellata reduced Cd, Cr, Cu more than Pb from the effluent. E. crassipes was most efficient Pb removing plant in 21 days of experiment.

Phytoremediation is an eco-friendly and cost-effective biotechnological method of wastewater treatment that involves the use of plants. In this research work, the potentials of Pistia stratiotes and Lemna minor aquatic plants in treatment of wastewater was examined. The two plants were cultivated in the wastewater sample for a period of 10 days. Water quality parameters (turbidity, chemical oxygen demand (COD), phosphate, ammoniacal nitrogen and nitrate) tests was subjected on the untreated (influent) and treated water (effluent) samples at a detention time of 24 hours. The outcome of the analysis demonstrates that P. stratiotes effluent achieved a reduction efficiency of up to 91.9%, 68%, 79.6%, and 71% for turbidity, phosphate, ammoniacal nitrogen and nitrate, respectively. Whereas for L. minor treated water samples, the highest reduction efficiency for turbidity, COD, phosphate, ammoniacal nitrogen and nitrate was found to be 87.2%, 46%, 48.7%, 83% and 56%, respectively. Hence, the overall outcome obtained indicate that P. stratiotes performed better in improving the quality of domestic wastewater compared to L. minor plants.

Durante o ano de 1999 foram conduzidos três experimentos em Botucatu-SP, em condições de caixas d'água, com o objetivo de estudar o efeito de alguns herbicidas sobre Pistia stratiotes, Eichhornia crassipes e Salvinia molesta. Os herbicidas e as doses utilizadas foram: diquat a 460, 960 e 1.400 g ha-1 com e sem o surfatante Agral a 0,1%; 2,4 D a 1.340; glyphosate a 3.360 g ha-1 mais 0,5% do surfatante Aterbane; e imazapyr a 250 g ha-1, além de uma testemunha sem aplicação de herbicida. Os estudos foram instalados no delineamento experimental em blocos ao acaso, com quatro repetições. As parcelas experimentais foram constituídas por caixas d'água com dimensões de 60 x 60 x 60 cm mantidas a pleno sol no campo. Utilizaram-se 18, 18 e 30 plantas/caixa de P. stratiotes, E. crassipes e S. molesta, respectivamente. Os herbicidas foram aplicados com pulverizador costal a pressão constante de CO2 a 1,75 bar, munido de barra com bicos 110.02 VS, com consumo de calda de 180 L ha-1. O herbicida diquat foi eficiente no controle de S. molesta, P. stratiotes e E. crassipes em todas as doses testadas. Para P. stratiotes, os herbicidas 2,4 D e imazapyr não proporcionaram controle, enquanto o herbicida glyphosate mostrou-se eficiente. Em relação a E. crassipes, os herbicidas 2,4 D e glyphosate foram eficientes em seu controle. Os herbicidas imazapyr, 2,4 D e glyphosate não foram eficientes no controle de S. molesta.

O objetivo deste estudo foi avaliar a influência de diferentes períodos de chuva ocorridos após a aplicação do herbicida imazapyr, em sua eficiência de controle sobre plantas de Pistia stratiotes e Eichhornia crassipes. Foram estudadas chuvas de 10 mm, aplicadas durante 5', em diferentes períodos de tempo (0h, 2h, 4h, 6h, 8h, 12h, 24h e não simulação de chuva) após a aplicação de imazapyr, na formulação Arsenal NA, a 250 g i.a. ha-1(1,0 L p.c. ha-1). O delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições. As plantas foram avaliadas visualmente aos 7, 14, 21, 28 e 35 dias após a aplicação (DAA), sendo os resultados obtidos submetidos à análise de variância pelo teste F e as médias dos tratamentos comparadas pelo teste de Tukey (p<0,05). A ocorrência chuvas em até 6 horas após a aplicação do herbicida imazapyr, em plantas de P. stratiotes, afetou negativamente sua eficiência de controle e, chuvas após intervalos acima de 8 horas não influenciaram no controle. A ocorrência de chuva em todos os intervalos de tempo, não interferiu no controle de plantas de E. crassipes.   UNITERMOS: aguapé, alface-d'água, controle químico, fitointoxicação     CAMPOS, C.F.; SOUZA, G.S.F.; PEREIRA, M.R.R.; MARTINS, D. EFFECT OF RAINFALL ON  IMAZAPYR  ACTION IN AQUATIC WEED CONTROL     2 ABSTRACT   The aim of this study was to evaluate the influence of different periods of rainfall that occurred after the application of the imazapyr herbicide on the control efficiency of Pistia stratiotes and Eichhornia crassipes. We studied 10 mm rainfall, applied for 5' at different time periods (0h, 2h, 4h, 6h, 8h, 12h, 24h, not simulated rainfall) after the application of imazapyr formulation Arsenal NA, 250 g ai ha-1 (1.0 L cp ha -1). The experiment had completely randomized design with four replications. Plants were evaluated at 7, 14, 21, 28 and 35 days after application (DAA), and the results submitted to analysis of variance by F test and treatment means compared by Tukey's test (p <0. 05). The occurrence of rainfall up to 6 hours after herbicide application, plants of P. stratiotes, negatively affected its efficiency and control; rainfall intervals over 8 hours had no effect in control. The occurrence of rainfall at all time intervals  did not affect the control of E. crassipes plants.  KEYWORDS: water hyacinth, waterlettuce, chemical control, phytotoxicity
