Background Ushuaia City has experienced much population growth and still lacks secondary treatment for its wastewater. As a result, most of the discharge is directed into the lotic ecosystems that cross the urban environment. This paper assesses the relationship between riparian areas and water quality along an urbanization gradient in the city's m...

La cuantificación de la concentración de clorofila-a fitoplanctónica (Chl-a) es una determinación de rutina en estudios limnológicos, ecológicos y ambientales. En este trabajo se realizó un relevamiento bibliográfico acerca de los métodos utilizados con mayor frecuencia en la actualidad para determinar Chl-a, con el objetivo de encontrar el método...

Emerging pollutants, including pharmaceuticals and personal care products, have been detected in surface and groundwaters. The adsorption of paracetamol and ibuprofen, two widespread drugs, has been studied in aqueous medium, using a ceramic-derived carbon (CeDC) and a commercial activated carbon (CoAC). CeDC yielded a BET surface area of 895 m 2 g...

Sustainable management strategies for highly polluted dredged sediments are crucial in ports and waterways, where dredging activities take place on a regular basis. In the case of Argentina, the lack of national legislation enables the unregulated sediment disposal in marginal areas, exposing low-resource populations to these sources of pollution....

Providing drinking water with safe arsenic (As) levels is a current, major challenge worldwide. The main As source is geogenic, and different water-solid phase interactions and geochemical processes control the As mobilization. As concentrations in drinking water have been reported up to 200 × the WHO recommended limit of 10 μg L− 1. Adsorption is...

Lanthanide and actinide (mainly from nuclear waste) removal and recovery from aqueous media have recently gained significant attention due to severe health issues related to chronic exposure. These elements tend to be expensive to recover and reuse. Critical waste management is needed for both safe waste disposal and recycling of these elements. Am...

Low-cost, eco-friendly and efficient charcoal-based composites have been developed to remove arsenic from two Argentine naturally contaminated groundwater samples. Iron compounds have been added to the charcoals both to enhance the composites’ sorption capacities and to provide permanent magnetization to the materials. The raw charcoals, one made f...

Soil amendments can be an effective and low-cost treatment to reduce metal bioavailability of contaminated dredged sediments disposed on land. The effect of green waste compost addition on Cu, Cr, Ni, Pb, and Zn extractability and bioaccumulation in lettuce was studied in a greenhouse experiment, using dredged sediments from different sites of the...

Biochar was obtained from Eucalyptus pruning residues with a non-conventional device named Kon-Tiki kiln. The average heat of combustion of the biochar, 27.3 MJ kg −1 , was higher than that of Eucalyptus wood, 17.8 MJ kg −1. Activation with CO 2 was performed by varying the activation time from 0 to 60 minutes. The activated carbons (ACs) and the c...

To design more efficient and versatile sorbent materials for wastewater treatment three magnetic beidellite composites with different cation exchange capacity and total specific surface area have been synthetized, characterized and used as Cs⁺ and Sr²⁺ sorbents. Total loaded Fe concentration and its distribution on the magnetic composites seems to...

La realización de huertas y talleres para jóvenes y niños desarrollados en el Barrio René Salamanca, del partido de La Matanza entre 2017 y 2019, surge de la motivación de los vecinos del barrio agrupados en la Asociación Civil "Identidad Vecinal". El trabajo se desarrolla en la huerta comunitaria "Rayito de Sol" con un impacto positivo en los part...

The remediation of contaminated dredged sediments is necessary to eliminate the risk towards human beings or the environment when there is disposal on land. A greenhouse experiment was carried out to evaluate the chemically assisted phytoextraction to clean up dredged sediment contaminated with Cr, Cu, Pb, and Zn. The ability of castor bean and chi...

Plant species with high biomass production can be used to remove metals through the harvest of aboveground biomass. However, low availability of metals in soil often limits their absorption and translocation, which reduces efficiency in phytoextraction process. The addition of organic ligands to soil is a potential strategy for increasing metal ava...

A través de una práctica experimental utilizada como herramienta didáctica se buscó acercar a los alumnos de la carrera de Licenciatura en Planificación y Diseño del Paisaje de la Facultad de Agronomía de la Universidad de Buenos Aires, temas de Química General con cierta complejidad e inherentes a su futura actividad profesional. Se llevó a cabo u...
