These articles have been peer-reviewed and accepted for publication in IJEnvH, but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

  • Applying reactive transport modelling in a chromium contaminated site in the Matanza-Riachuelo basin, Buenos Aires, Argentina   Order a copy of this article
    by Elina Ceballos, Sergio Andrés Bea, Romina Sanci 
    Abstract: Chromium (Cr) is one of the main pollutants affecting both soil and groundwater systems in some areas within the Matanza-Riachuelo River Basin in Argentina. The particular site of study is located near an abandoned tannery and chemical industry facilities. Cr toxicity and mobility depend on its oxidation state: Cr(VI) is an active carcinogen, more soluble and mobile, whereas Cr(III) shows low toxicity and solubility, precipitating in the form of amorphous Cr(OH)3(am). This paper is devoted to elucidate the main key controls on the Cr(VI)-plume transport at this site using reactive transport (RT) modelling, and uncertainty quantification analysis tools. RT results suggest a Cr source term on the surface to explain the observed Cr concentrations in both Pampeano and Puelche aquifers. UQ analysis indicates that the Cr(VI) concentrations in both aquifers are sensitive to hydraulic connectivity between them, the reaction reduction rates Cr(VI)-Cr(III), and the organic matter contents.
    Keywords: reactive transport modelling; hexavalent chromium; groundwater; Matanza-Riachuelo River Basin.

  • Use of speciation modelling of heavy metals in Los Patos lagoon, Argentina, to improve waterbody management   Order a copy of this article
    by Erica Sanchez, Lucila Elordi, Leonardo Cano, Esteban Colman Lerner, Santiago Elisio, Soledad Represa, Dario Andrinolo, Andres Porta 
    Abstract: Levels established in water quality guidelines for protection of aquatic life are based on the total concentrations of heavy metals regardless of speciation. However, there are numerous studies that show the importance of determining both the physicochemical characterisation of waterbodies, and the total concentration of heavy metal in them, including their chemical speciation, given the specific correlation with the bioavailability. In this regard, the objective of this study is to quantify concentrations of heavy metals in Los Patos lagoon, Argentina, and to show the utility of estimating with Visual Minteq software the fractions in which these metals are forming aqueous inorganic species or are complexed with organic matter. The results demonstrate the relevance of using speciation calculations of metal cations, particularly when their concentrations are in the order of guide levels.
    Keywords: Visual MINTEQ; speciation; bioavailability; trace metals.

  • Atmospheric gas-particle partitioning of E-EHMC and Z-EHMC estimated from their liquid vapour pressures at 298.15 K.   Order a copy of this article
    by Malisa Chiappero, César Nicolás Pegoraro, Hernán Alfredo Montejano 
    Abstract: The UVB filter E-ethylhexyl p-methoxycinnamate (E-EHMC) is extensively used as a UV protectant in commercial products. Its photoisomerisation into Z-EHMC is well known. In this work, we estimate the thermodynamic properties of the vaporisation processes of E-EHMC and Z-EHMC using an indirect experimental method developed in our laboratory named Effusion Method under Atmospheric Pressure (EMAP). The atmospheric particle bound fractions and air-particulate partition coefficients for E-EHMC and Z-EHMC were derived from the vapour pressure P/Pa (298.15 K) estimated by EMAP methodology.
    Keywords: vapour pressure; air-particulate partition coefficient; EMAP; particle-bound fraction.

  • Safe disposal of solid wastes generated during arsenic removal in drinking water   Order a copy of this article
    by Elizabeth Graciela De Seta, Fernando Damián Reina, Fernando Isaac Mugrabi, Luis Eugenio Lan, Juan Pablo Guerra, Aitor Porcel Laburu, Esteban José Domingo, Jorge Martín Meichtry 
    Abstract: Wastes generated during the treatment of water containing arsenic were mixed with Portland cement in 3:1 volume ratio, to produce mortars that were then used to manufacture monolithic bricks. Two different wastes, containing 1.0 x 103 and 2.0 x 103 mg As per kg of dried waste, were generated in experiments of aqueous trivalent arsenic removal ([As(III)] = 50 mg L-1) removal in columns filled with a mixture of zero-valent iron and sand (1% w/w of ZVI). The mechanical tests indicated that the waste-containing bricks showed a decrease in the compression tests, while no significant differences were found in the flexural tests. Studies on arsenic leaching indicated that, in normal conditions, the amount of released arsenic is not significant, as extreme conditions are required to exceed the maximum allowable limit for non-hazardous waste. Even though the quality of the resulting mortar is lower, it is still well suited to make bricks for use in the construction of foundations or for final disposal in landfills.

  • Study of physicochemical changes of polluted sediments from Reconquista river basin (Argentina) after remediation processes   Order a copy of this article
    by Melisa S. Olivelli, Myrna J. Simpson, Natalia Porzionato, Mariela Fernandez, Rosa Torres Sanchez, Gustavo Curutchet 
    Abstract: The physicochemical properties of sediments and their ability to retain pollutants are affected both by contamination and by remediation processes. The aim of this study is to determine structural and physicochemical changes in real sediment contaminated with metals, subjected to bioleaching processes in a previous study. The sediment contaminated with heavy metals and samples of the same sediment treated with different heap leaching tests were used. They were characterised by potentiometric titrations, electrophoretic mobility, organic matter (OM), nuclear magnetic resonance, volatile solids and sulfides. For contaminated and treated sediment samples, the results of organic matter, sulfides, volatile solids heated to 600 degrees, potentiometric titrations and surface charge depended on the bioleaching treatment performed previously. The contaminated sediment sample without any bioleaching treatment presented the greatest amount of OM and sulfides. Moreover, metal adsorption isotherms were derived. The contaminated sediment without bioleaching treatment was the one with the highest adsorption capacity. The pristine sample did not present a noticeable adsorption capacity. This study indicates the importance of the contribution of OM and sulfides to sediments and structural and physicochemical studies after remediation treatments.
    Keywords: sediments; remediation; physicochemical properties.
