Special Issue Information

Dear Colleagues,

Among all the pollutants widely released in aquatic environments, trace metals can reach and accumulate in the aquatic or terrestrial food chain when contaminated waters are used for irrigation. Their distribution, mobility, bioavailability, and toxicity are strongly related to their speciation in waters and sediments. Recent developments in isotopic geochemistry have allowed the scientific community to discriminate, in some case studies, natural from anthropogenic sources of metals that can help to reduce human exposure. The current Special Issue of Water focuses on the links between drinking and/or surface and groundwater quality, major and trace metallic elements, contaminant sources, and the health risks associated to the human exposure. This Special Issue will cover recent water studies led in Northern and Southern countries, including new issues related with surface water exposure assessment and environmental and health risks. Papers dealing with surface, groundwater or drinking water standards, policies, and sustainable management are also welcome in this Special Issue. Original research papers, reviews, and technical notes are also invited. Submission of transdisciplinary research, including socioeconomic perspectives, and review papers within the broad theme of water quality are particularly encouraged.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind 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 semimonthly 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 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The release of heavy metals and metalloids (HMs), including Pb, Zn, Cd, As, and Cu, from two typical contaminated soils with different properties, namely red soil and limestone-dominated soil, was characterized through simulated-rainfall experiments in order to investigate the effects of soil properties on HM release. Significant differences in the HM concentrations between the two soils resulted in various concentrations of dissolved and particulate HMs in the runoff. Differences in the dissolved HM concentrations in the runoff were inconsistent with the HM concentrations in the soils, which is attributed to the variable solubilities of HMs in the two soils. However, the HM enrichment ratios were not significantly different. The strong correlation between dissolved organic carbon and dissolved HMs in the runoff, and between the total organic carbon and particulate HMs in sediments, were observed, especially in the limestone-dominated soil. The specific surface area and HM concentrations in sediments were weakly correlated. Acid-rainfall experiments showed that only the limestone-dominated soil buffered the effects of acid rain on the runoff; the concentrations of dissolved Pb, Zn, Cd, and Cu increased in the red soil under acid rainfall and were 60, 29, 25, and 19 times higher, respectively, than under the neutral conditions. The results contribute to the understanding of HM behavior in the two typical soils in southern China, exposed to frequent storms that are often dominated by acid rainfall. Full article
