As macrófitas aquáticas colonizam o reservatório de Santana desde seu enchimento em 1955 em função da eutrofização da água, especialmente a ingressa pelo Canal de Santa Cecília, bombeada do Rio Paraíba do Sul. A colheita mecânica é o principal método adotado para a retirada destas plantas, visando prevenir interferências no meio ambiente e usos múltiplos da água e do corpo hídrico. Este trabalho foi realizado por três anos com o objetivo da avaliar as composições químicas das principais macrófitas que formam a biomassa retirada pela colheita mecânica e inferir sobre os riscos de sua utilização na recuperação de solos de áreas degradadas. As macrófitas avaliadas foram Salvinia molesta, Eichhornia crassipes, Pistia stratiotes, Enydra sessilis, Polygonum lapathifolium, Eichhornia azurea, Urochloa subquadripara, Panicum rivulare, Egeria densa e Potamogeton pectinatus. Os padrões de concentrações de nutrientes foram diferentes entre plantas marginais, flutuantes e submersas, houve variação sazonal dentro das espécies, os valores foram compatíveis com a literatura e as concentrações de metais pesados foram abaixo das exigências legais para fertilizantes orgânicos. Os resultados sugerem baixo risco ambiental da utilização direta desta biomassa na recuperação de áreas degradadas.

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.

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 aim of this study was to assess the effectiveness of glyphosate, as Rodeo(r) formulation, to control Eichhornia crassipes, Pistia stratiotes, Salvinia molesta, Salvinia herzogii and Urochloa subquadripara, under greenhouse conditions. The doses assessed were (480, 960, 1440, 1920, 2400, 2880, 3360 and 3840 g ha-1 of glyphosate) with 0.5% of the Aterbane(r) BR surfactant and a control, with no herbicide application. All experiments were conducted in a completely randomized experimental design with ten replications. Applications were carried out by precision backpack sprayer at a CO2 constant pressure of 25 psi and spray solution consumption of 200 L ha-1. Product effectiveness was determined by assessing the growth inhibitions and phytotoxicity signals during the periods of 3, 7, 15, 21, 30 and 45 days after application (DAA). At 45 DAA, the highest glyphosate dose (3840 g ha-1) displayed 100% effectiveness for all four macrophyte species. Under greenhouse conditions, the glyphosate in formulation Rodeo(r) with 0.5% of Aterbarne(r) BR surfactant showed excellent effectiveness, inhibiting the growth of the floating aquatic macrophytes. This procedure can be included on the tillage plans for these species.

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.

Phytoremediation is an emerging low cost green technology, which uses plants for treating contaminant in the environment. Phytoremediation potential of locally available aquatic plants Eichhornia crassipes (water hyacinth), Pistia stratiotes (water lettuce) and Salvinia molesta (water fern) in the treatment process of textile wastewater was investi-gated. The reduction efficiencies of chemical oxygen demand (COD), total solids (TS), total suspended solids (TSS), total dissolved solids (TDS), nitrates, phosphates, heavy metals (Cd, Ni and Zn) and total and fecal coliform from the waste-water by each plant species were estimated. Bioconcentration factors (BCF) and translocation factors (TF) of three plant species for Cd, Ni and Zn were also estimated in order to identify their heavy metal absorption and translocation capacity. The results of the study indicated that greater reduction of COD, nitrates, phosphates, total coliform and Zn from the ini-tial wastewater by the three plant species. The results of the study also suggested that the selected aquatic plants are hy-peraccumulators of Cd, Ni and Zn metals. The findings of this study suggest that E. crassipes, P. stratiotes and S. molesta are potential aquatic plants for treating textile waste water.
