- Abstract
Objectives: The purpose of this work was to compare nutrient concentrations in water, sediment, and in plant tissues of Eichhornia crassipes and Panicum elephantipes from lotic and lentic environments of the Middle Parana River floodplain (Argentina). Materials and Methods: The study was carried out over an 18-month period. Plants, water, and sediment were collected in a lake (lentic environment) and in a river (lotic environment) from the Middle Parana River floodplain. Water and sediment were sampled in sites where P. elephantipes or E. crassipes were predominant and in sites without vegetation. Results and Discussion: The lentic and lotic environments dominated by E. crassipes showed the highest ammonium concentrations. The sediment from the lotic environment showed total phosphorus (TP) and total Kjeldahl nitrogen (TKN) concentrations significantly lower than those found in the sediment from the lentic environment. In the lentic environment, the sediment from the lake with the dominance of E. crassipes showed the highest TKN concentration, while the sediment from the lake dominated by P. elephantipes showed the highest TP concentration. For both plant species and for both environments, TKN and TP tissue concentrations were significantly higher in leaves in comparison with roots. Conclusions: Our results could be used to optimize the efficiency of treatment wetlands. Additionally, the use of locally available macrophytes as contaminant bioaccumulators in the Middle Parana River floodplain is completely feasible., Objetivos: el objetivo de este trabajo fue comparar las concentraciones de nutrientes en agua, sedimento y en tejidos vegetales de Eichhornia crassipes y Panicum elephantipes estudiadas en ambientes lóticos y lénticos de la llanura aluvial del río Paraná Medio (Argentina). Materiales y Métodos: el estudio tuvo una duración de 18 meses. Plantas, agua y sedimento fueron colectados en una laguna (ambiente léntico) y en un río (ambiente lótico) de la llanura aluvial del río Paraná Medio. Agua y sedimento fueron colectados en sitios dominados por P. elephantipes o E. crassipes, y en sitios sin vegetación. Resultados y Discusión: los ambientes lénticos y lóticos dominados por E. crassipes mostraron las concentraciones de amonio más altas. El sedimento del ambiente lótico mostró concentraciones de fósforo total (PT) y nitrógeno total Kjeldahl (NTK) significativamente menores que las del sedimento del ambiente léntico. En este ambiente, el sedimento de la laguna dominada por E. crassipes mostró la concentración más alta de NTK, mientras que el sedimento de la laguna dominada por P. elephantipes mostró la concentración más alta de PT. Para ambas especies y ambos ambientes, las concentraciones de NTK y PT en tejidos vegetales fueron significativamente mayores en hojas que en raíces. Conclusiones: nuestros resultados podrán ser utilizados para optimizar la eficiencia de humedales de tratamiento. Además, el uso de macrófitas localmente disponibles como bioacumuladoras de contaminantes en la llanura aluvial del río Paraná Medio, es completamente factible

Chromium (Cr), Nickel (Ni), and zinc (Zn) removal from landfill leachate using mesocosm-scale vertical flow wetlands, the effect of recirculation, and the ability of macrophytes to retain metals were evaluated. Wetlands were filled with coarse sand and light expanded clay aggregates and planted with Typha domingensis or Canna indica. Wetlands were operated using intermittent loading, with and without recirculation. Raw leachate was diluted and spiked with metals to reach the following concentrations: 0.2 mg L−1 Cr , 0.2 mg L−1 Ni, and0.2 mg L−1 Zn and 1.0 mg L−1 Cr, 1.0 mg L−1 Ni, and 1.0 mg L−1 Zn. Wetlands planted with T. domingensis presented higher metal removal than those planted with C. indica. Recirculation enhanced metal removal efficiencies significantly, being for T. domingensis/C. indica: 60/54, 49/47, 61/47% for Cr, Ni, and Zn at 0.2 mg L−1, and 80/71, 76/62, 73/59% for Cr, Ni, and Zn at 1.0 mg L−1, respectively. Metals were efficiently retained by macrophytes. Plant biomass and metal concentrations in roots were significantly higher than in shoots. Scanning electron microscopy and X-ray microanalysis showed that metals were absorbed by internal root tissues. A hybrid wetland planted with T. domingensis may be implemented to improve not only metal but also chemical oxygen demand and total nitrogen removals. Landfills generate leachate that contains a wide range of contaminants in concentrations that vary over time. Even when a landfill ceases to receive solid waste, the leachate will continue to be generated for years. To avoid environmental impact, such leachate should be treated. This work evaluated chromium (III), nickel (II), and zinc (II) removal from landfill leachate using vertical flow wetlands (VFWs) at mesocosm-scale. The performance of wetlands planted with Typha domingensis or Canna indica, and with and without recirculation were compared. VFWs have demonstrated to be efficient for landfill leachate treatment. At a global scale, studies on metal removal using this type of wetlands are scarce. Despite the advantages of treatment wetlands in Argentina (easy operation and maintenance and usual large availability of land inside factories), they are scarcely implemented. [ABSTRACT FROM AUTHOR]

Bahco metallurgical industry for toolmaking needed an effluentfinal stage treatment. A large land area was available in thefactory facilities and costs for maintance and operation ofwatewater treatment are limiting factors in Argentina. In addition,sewage from the factory also required a final treatment.A FWS wetland was constructed. This type of TW was selecteddue to the efficiency in metal removal and the low costs foroperation and maintenance. Although FWSs requires a largearea, this is not a problem in this case. Industrial wastewatercontaining metals and sewage from the factory are treatedtogether, both after a primary treatment (25 m3 d-1 of sewage +75 m3 d-1 of industrial wastewater). Sewage improves the abilityof macrophytes to take up heavy metals from wastewater. Fil: Maine, Maria Alejandra. Universidad Nacional del Litoral. Instituto de Química Aplicada del Litoral.

- Abstract
This work assesses the Cr accumulation and tolerance of Typha domingensisafter an accidental discharge of wastewater that produced a concentration of Cr(VI) of approximately 120 mg L−1in a free-water surface wetland. The wetland was constructed for the final wastewater treatment of a metallurgical manufacturing plant. It is 7 m wide, 20 m long, and waterproofed with a geomembrane. A 1.5 m soil layer was placed on top of the geomembrane. Water, plants, and sediment were sampled before and after an accidental discharge. The root anatomical measurements of the plants from the treatment wetland were compared with those of plants from an uncontaminated wetland (control). Roots and dead leaves from the inlet plants showed the highest Cr concentrations after the accidental discharge (12.4 and 11.6 mg g−1, respectively). SEM-EDX mapping determined that Cr was accumulated in root epidermis. Cr accumulation in plant detritus, plant roots, and sediment were the mechanisms for Cr removal. Plants accumulated Cr in belowground tissues demonstrating their potential for phytostabilization. T. domingensiswas capable of modifying its morphology to respond to high Cr concentrations. This macrophyte is a suitable species for wetlands constructed for the treatment of a wastewater with high Cr(VI) concentration. The studied system was capable of minimizing the impact and preserving the environment.

El valle aluvial de los grandes ríos de llanura presenta numerosos humedales naturales donde se desarrolla una abundante y variada vegetación acuática. En su hábitat natural las macrófitas se encuentran formando asociaciones en el margen e interior de los lagos. Estas asociaciones se corresponden con zonas de colonización relacionadas íntimamente con el nivel de agua y la topografía, por lo que, de acuerdo a su morfología, las macrófitas pueden clasificarse como emergentes, flotantes libres, sumergidas o arraigadas con hojas flotantes(Fig. 1). Así, se reconoce una zona litoral caracterizada por vegetación emergente, una segunda zona más profunda, con asociaciones de macrófitas con hojas flotantes y una zona más interna habitada por plantas sumergidas. Las especies emergentes, son plantas arraigadas que se desarrollan en los bordes de los cuerpos de agua y son capaces de soportar períodos de inundación y sequía. Las especies de hojas flotantes se desarrollan en zonas más profundas que las anteriores, se encuentran arraigadas al fondo y sus láminas foliares se encuentran flotando sobre la superficie del agua. Las macrófitas flotantes libres habitan en cualquier parte del cuerpo de agua según la corriente y el viento y en los ríos pueden desplazarse a la deriva empujadas por la corriente. Las macrófitas sumergidas pueden mostrar partes aéreas sobre la superficie del agua, como las flores o porciones de tallos, pero la mayor proporción se encuentra bajo el agua pudiendo arraigarse o no al fondo, según las especies.Las diferentes formas de vida vegetal coexisten y algunas hasta crean condiciones favorables para el establecimiento de otras.

A free water surface wetland was built in 2002 to treat wastewater from a tool factory containing metals (Cr, Ni, Zn and Fe), nutrients and organic matter. Until 2006, the last reported period, the wetland retained metals and stored them primarily in the bottom sediment and in the biomass of macrophytes secondarily. The aim of this work was to study metal retention and distribution in the sediment of a constructed wetland for industrial wastewater treatment. Total concentrations and fractions (exchangeable, carbonate-bound, Fe-Mn oxides-bound, organic matter-bound and residual) of metals in sediment were analyzed in this treatment wetland, in order to estimate the fate of metals over time. Metal concentrations were significantly higher in the inlet than in the outlet sediment; concentrations in the latter remained without significant differences throughout the testing period. Metal concentrations and redox potential decreased with depth within the sediment. The lowest metal concentrations and pH and the highest redox values were attained in spring, in agreement with the period of maximum macrophyte growth. Ni and Zn were mainly stored associated with the carbonate fraction; Cr was mainly associated with the Fe-Mn oxides fraction, while Fe was mainly associated with the residual fraction, probably as pyrite. The incoming wastewater composition containing high pH, carbonate, calcium and Fe concentrations favored the observed association in the surface sediment. It would be expected that sediment will continue retaining metals in fractions that will not release them into the water while the chemical and environmental conditions remain unchanged.

Fil: Hadad, Hernán Ricardo. Universidad Nacional del Litoral. Facultad de Bioquímica y Ciencias Biológicas; Argentina. Vegetation and removal efficiency were studied in a pilot-scale (6m x 3m x 0.4m) and a definitive (40m x 50m x 0.5m) constructed wetlands for the treatment of industrial and sewage effluents from the metallurgic industry Bahco Argentina S. A. The influent had Cr, Ni and Zn and high conductivity and pH. The pilot-scale wetland showed an efficient removal of all the variables measured, except soluble reactive phosphorous (SRP) and ammonium. The floating macrophytes showed an initial growth but they disappeared later. According to the results obtained in the pH, conductivity and metal toxicity experiments, it was concluded that the influent conductivity and pH were toxic for the floating species. Typha domingensis showed a higher biomass than that of a natural wetland. The definitive wetland removed efficiently all the contaminants except bicarbonate, SRP and ammonium. Anoxic conditions were registered in several samplings. Three macrophyte dominance stages were identified. The first stage was represented by Eichhornia crassipes, the second one by E. crassipes and T. domingensis, and the third one by T. domingensis. With exception of SRP and ammonium, no significant differences in the removals were registered among the stages. In the E. crassipes stage metals were retained by vegetation because of anoxic conditions. In the other dominance stages, the contaminant removal was carried out by vegetation but principally by sediment in relation with the rizosphere oxygenation. T. domingensis showed a positive growth being the best alternative to be used in treatment systems with high conductivity and pH. Se estudió la vegetación y la eficiencia de remoción de humedales construidos a escala piloto (6m x 3m x 0,4m) y definitiva (40m x 50m x 0,5m) para la depuración del efluente industrial y cloacal de la industria metalúrgica Bahco Argentina S. A. El afluente tenía Cr, Ni, Zn y elevada conductividad y pH. El humedal piloto removió eficientemente todos los parámetros excepto el fósforo reactivo soluble (PRS) y amonio. Las macrófitas flotantes crecieron inicialmente pero luego desaparecieron. Se realizaron experimentos de toxicidad al pH, salinidad y metales concluyendo que la salinidad y el pH del afluente fueron tóxicos para las especies flotantes. Typha domingensis alcanzó una biomasa mayor que en un ambiente natural. El humedal definitivo removió eficientemente todos los contaminantes excepto el PRS, bicarbonato y amonio, registrándose anoxia en muchos muestreos. Se identificó una primer etapa de dominancia de vegetación representada por Eichhornia crassipes, la segunda, por E. crassipes y T. domingensis, y la tercera, por T. domingensis. No existieron diferencias significativas entre las etapas en los porcentajes de remoción, excepto para el PRS y amonio. Durante la dominancia de E. crassipes, los metales fueron retenidos por la vegetación debido a las condiciones de anoxia. Durante la dominancia mixta y de T. domingensis, la remoción la realizó la vegetación y sedimentos, aunque principalmente éstos últimos, en relación con la oxigenación de la rizósfera. Debido a que T. domingensis creció hasta el final del estudio, es la mejor alternativa para sistemas de tratamiento de alta salinidad y pH.

Los humedales o wetlands han demostrado ser altamente eficientes en la remoción de contaminantes, son de bajo costo de instalación y mantenimiento, operables por mano de obra no especializada e integrables funcionalmente con el entorno. El objetivo de este trabajo fue evaluar la eficiencia de un wetland construido para la depuración en forma conjunta del efluente industrial y el cloacal de una industria metalúrgica. Las dimensiones del mismo son de 50 m de largo por 40 m de ancho y profundidad de 80 cm, con un tabique central de manera que la relación largo-ancho sea 5:1. Está impermeabilizado con bentonita, y las plantas se arraigan sobre una capa de 1 m de suelo. Se transplantaron macrófitas de la zona del Río Paraná Medio: Eichhornia crassipes (jacinto de agua), Typha domingensis (totora) y Pontederia cordata (aguapey), entre otras. La eficiencia del humedal se determinó analizando la composición química del efluente a la entrada y salida. En sedimentos y vegetales se determinó P, Cr, Ni y Zn. El muestreo se realizó quincenalmente durante 2 años. El wetland eficientemente disminuyó las concentraciones medias y la variabilidad de los parámetros analizados, salvo en el caso de fosfato y amonio debido a la anoxia. Las remociones medias fueron de 86% para Cr, 67% para Ni, 95% para Fe, 70% para nitrato, 60% para nitrito, 78% para DQO, 77% para DBO. Las concentraciones de Zn en el afluente estuvieron por debajo de los 50 μg.l-1 en la mayoría de los muestreos. La concentración de metales no aumentó significativamente en el sedimento de fondo después de 2 años de operación. Un aumento en la concentración de metales y nutrientes en los tejidos de las macrófitas, así como también el aumento de la biomasa, representó el principal mecanismo de remoción de contaminantes. La ventaja de las macrófitas es la posibilidad de ser cosechadas, lo que conduce a importantes tasas de remoción en corto tiempo. La superficie del wetland se cubrió en un 80% de E. crassipes, lo que probablemente contribuyó a la disminución de oxígeno en agua. Disminuir el nivel de agua contribuiría a favorecer la dominancia de las macrófitas enraizadas y a aumentar la concentración de oxígeno en agua. La calidad del efluente se mejoró diseñándose la salida del mismo a nivel superficial., Instituto de Limnología "Dr. Raúl A. Ringuelet"

Fil: Nocetti, Emanuel. Universidad Nacional del Litoral. Facultad de Ingeniería y Ciencias Hídricas; Argentina. Los efluentes lácteos poseen elevado contenido de compuestos nitrogenados, además de materia orgánica y fósforo. Debido a que Santa Fe se localiza en una región caracterizada por un significante número de industrias lácteas, el tratamiento de sus efluentes es un tema que concierne a la región. El objetivo general de la presente Tesis fue evaluar el rendimiento de humedales construidos para tratar el efluente de una industria láctea local. Para esto, se realizaron estudios en humedales a escala microcosmos en invernadero y a escala piloto en campo. Los objetivos de los estudios a escala microcosmos fueron seleccionar la especie de macrófita y sustrato más adecuado y cuantificar la influencia de la vegetación en el tratamiento mediante la aplicación de un modelo cinético simple de primer orden. Los estudios en la escala piloto se enfocaron en determinar la eficiencia de remoción de contaminantes y evaluar el efecto de diferentes velocidades de carga superficial sobre la velocidad de remoción superficial de materia orgánica y nutrientes bajo condiciones reales. Los datos colectados del sistema a escala piloto fueron utilizados para calibrar parámetros de modelos en un esfuerzo de predecir el rendimiento del humedal bajo diferentes posibles escenarios de operación. Las simulaciones realizadas permitieron demostrar la competencia establecida por el consumo de oxígeno entre los contaminantes. El sistema de humedales ha demostrado ser eficiente en el tratamiento del efluente lácteo para las estrategias evaluadas. Dairy wastewater has a high content of nitrogenous compounds, in addition to organic matter and phosphorus. Since Santa Fe is located in a region characterized by a significant number of dairy industries, the treatment of their effluents is an issue that concerns the region. This work focused on evaluating constructed wetland performance to treat these wastewaters. For this, microcosms and pilot-scale wetland studies were carried out. The aims of the studies at microcosms-scale were to select the most suitable macrophyte species and substrate to be used in wetlands for the treatment of wastewater from a local dairy industry, and to quantify the influence of plant species by applying a simple first-order kinetic model. The studies at the pilot-scale wetland was aimed to determine pollutant removal efficiencies from the dairy wastewater and evaluate the effect of different surface loading rate on surface removal rate of organic matter and nutrient under real conditions. The collected data from pilot-scale system were used to fit model parameters in an effort to predict wetland performance under different possible operating scenarios. The simulations carried out demonstrated the competition that establishes the consumption of oxygen among pollutants. The system demonstrated to be efficient in the treatment of the dairy wastewater for the strategies evaluated.

Fil: Mufarrege, María De Las Mercedes. Universidad Nacional del Litoral. Facultad de Bioquímica y Ciencias Biológicas; Argentina. Se estudió la tolerancia y eficiencia de Typha domingensis en la retención de metales y nutrientes de efluentes industriales. Se monitoreó un humedal construido, determinando metales y nutrientes en diferentes órganos vegetales, en los efluentes y en el sedimento de la zona de entrada y de salida, así como también la tolerancia de las plantas a las condiciones del sistema. En experiencias de invernadero, se evalúo la respuesta de T. domingensis al ser expuesta a condiciones extremas de pH y salinidad y a diferentes concentraciones de metales y la capacidad de biosorber metales en sus hojas secas. Las plantas del humedal construido adquirieron adaptaciones fisiológicas y morfológicas para tolerar elevados valores de pH y salinidad, demostradas por una mayor tasa de crecimiento relativo y un incremento en la concentración de clorofila, en comparación con los obtenidos en plantas provenientes de un humedal natural expuestas a las mismas condiciones. La alta eficiencia de remoción de metales por hojas secas de T. domingensis, alcanzada en soluciones multimetales permitiría proponer que las hojas de esta especie sean cosechadas durante las operaciones de mantenimiento de un wetland construido, dándole una disposición final a estos residuos. T. domingensis demostró una alta eficiencia en la retención de metales y nutrientes y una elevada tolerancia a las condiciones de los efluentes tratados debido a su capacidad de adaptación. The tolerance and efficiency of Typha domingensis in the retention of metals and nutrients from industrial effluents were studied. A constructed wetland was monitored by determining metals and nutrients in different plant organs, and in effluents and sediments of the inlet and outlet zones, as well as, the plant tolerance to the conditions of the system was studied. In greenhouse experiments the responses to extreme conditions to pH and salinity and to different metal concentrations were evaluated. The capacity of metal biosorption by dry leaves was evaluated. Regarding salinity and pH, it was probed that the plants from the constructed wetland acquired physiological and morphological adaptations to tolerate high values. The adaptations of the plants from the constructed wetland were demonstrated by a higher relative growth rate and an increase in the chlorophyll concentration in comparison with the values obtained in plants from a natural wetland exposed to the same conditions. The high efficiency in metal removal achieved in multimetal solutions would propose that when the leaves of T. domingensis are harvested during the maintenance of a constructed wetland, this material could be used as an efficient biosorbent, giving a final disposal of these wastes. T. domingensis proved a high efficiency in the nutrient and metal retention and a high tolerance to the conditions of the treated effluents due to its adaptation ability.
