Special Issue Information

Dear Colleagues,

There is a growing demand for more knowledge-based abatement actions on inorganic pollutants in the water environment. Grounds for this are large and increasing emissions in emerging economies (esp. China and India) and stricter regulations such as dictated in the Water Framework Directive in Europe. We need enhanced mechanistic understanding of the hydro-biogeochemical processes governing mobilization, transport, fate and effects of pollutants in order to assess and implement the best abatement actions. Dissolved natural organic matter (NOM) plays a key role in studies of pollutants and its role in transport of pollutants needs to be better understood. Climate change affects the hydrological cycle as well as temperature and may thus have an effect on the governing processes of importance for the concentration levels and ecological effects of water pollutants.

New advances in the environmental research are made possible through better analytical tools, including improved methodology for fractionation and/or speciation of the contaminants, and multivariate chemometric analysis on comprehensive environmental data. I would therefore like to call for papers where you share your recent discoveries within the field of inorganic pollution of the water environment.

Papers will be selected by peer review with the expected outcome being wide dissemination of research results. Original research articles as well as review articles on all aspects of inorganic pollutants in water are of interest.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 500 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Abstract: A groundwater, sediment and soil chemistry and mineralogical study has been performed to investigate the sources and mobilization process of Arsenic (As) in shallow aquifers of Bangladesh. The groundwater from the shallow aquifers is characterized by high concentrations of Arsenic (47.5–216.8 µg/L), iron (0.85–5.83 mg/L), and phosphate, along with high electrical conductivity (EC). The groundwater has both very low oxidation-reduction potential (Eh) and dissolved oxygen (DO) values indicating reducing conditions. By contrast, the deep aquifers and surface waters (pond, canal) have very low concentrations of Arsenic ( < 6 µg/L), iron (0.12–0.39 mg/L), and phosphate along with a relatively low EC. Furthermore, the values of Eh and DO are high, indicating oxic to suboxic conditions. Arsenic is inversely correlated with Eh values in the upper aquifer, whereas no relationship in the deeper aquifer is observed. These results suggest that As mobilization is clearly linked to the development of reducing conditions. The clayey silt, enriched in Fe, Mn, Al oxides and organic matter, and deposited in the middle unit of shallow aquifers, contains moderately high concentrations of As, whereas the sediments of deep aquifers and silty mud surface soils from paddy fields and ponds contain a low content of As (Daudkandi area). Arsenic is strongly correlated with the concentrations of Fe, Mn and Al oxides in the core samples from the Daudkandi and Marua areas. Arsenic is present in the oxide phase of Fe and Mn, phyllosilicate minerals and in organic matter in sediments. This study suggests that adsorption or precipitation of As-rich Fe oxyhydroxide on the surface or inner sites of biotite might be responsible for As concentrations found in altered biotite minerals by Seddique et al. Microbially or geochemically mediated reductive dissolution of Fe oxyhydroxides is the main mechanism for As release. The reducing conditions are caused by respiratory decomposition of organic matter, either sedimentary or labile organic C. The process can be accelerated by agricultural activity and domestic organic wastes. An agricultural fertilizer can directly contribute As to groundwater as well as promote As mobilization by ion-exchange with phosphorus.

Abstract: Sweden has adopted a system of Environmental Quality Criteria (EQC) that address the widespread need for assessing the current status and degree of human influence on the environment. Since EQC are intended for application by many different organizations to provide information that is readily accessible to decision-makers and the public, the system does not require specialist expertise by either those who apply it, or those who use the results. Useful as EQC can be for establishing management priorities and monitoring changes over time, the simplifications inherent in assessment systems such as EQC may compromise their value. This paper examines the performance of four criteria in an application of the Swedish EQC to surface waters of the Dala River Basin. The EQC could be readily applied using existing monitoring data, and some indicators were judged to work well by experts familiar with the Dala River. Other parameters, however, both biological and chemical, performed less satisfactorily, in part due to the influence of climate. It was concluded that EQC could make a valuable contribution to environmental assessment, particularly by bringing a broader spectrum of managers, stakeholders and politicians into contact with environmental data and a coherent overview of the situation in the river basin. The value of that contribution, however, is contingent upon an expert review of the results that identifies potential problems in the specific EQC application where greater expertise is required for a satisfactory assessment. We suggest that this is likely to be true for many other assessessment systems.
