Developing legislation on soil protection, including soil quality standards, is not straightforward for areas with high geogenic metal(loid) concentrations in rocks and soils. Several rock types in southern Luxembourg (laterally continuous into Northern France and Southern Belgium) contain elevated potentially toxic element concentrations. Toarcian and Aalenian Minette ironstones, and soils on top, possess high As concentrations (average of ~100 ...

Travertines and their springs are rarely investigated as a source of toxicity. Remarkably high contents of As (up to 10 g/kg) have been found in travertine deposits and associated spring waters, nearby Ghorveh city (western Iran). Two types of travertines were distinguished: (i) Fissure ridge travertines, in areas with a carbonate-dominated basement, are characterized by a relatively low content and leaching of As. Their spring waters contain ...

As business education around the world is becoming increasingly focused on integrating ethics, responsibility, and sustainability (ERS) into curricula, measuring and disclosing ERS inclusion in course content is becoming a pressing task. This article provides insights on how a ‘broad, horizontal’ approach to ERS curricular assessments can inform internal strategy development in higher education. The results of a case study at a Belgian ...

Antimony (Sb) is an element with a growing concern due to its toxicity, but also because of its criticality. While the impact of Sb mining is documented in literature from China and Europe, still little data is available concerning the environmental impact of Sb mining in Vietnam. This paper presents the results of an exploratory study of mine waste and soil samples from the Mau Due mine (North Vietnam). The chemical and mineralogical ...

The geochemical and mineralogical characterization of mine waste provides essential information to understand the environmental and health impacts and to adequately manage present and historical mine waste sites. In the present study, mine waste samples from a former Zn-Pb mining site were subjected to different types of leaching tests, an in-vitro bioaccessibility test, and a mineralogical analysis. The samples were characterized by elevated ...

“Schistes carton”, Jurassic black shale rocks occurring in the south-western part of the Grand Duchy of Luxembourg, were investigated, based on a combined mineralogical and geochemical approach. The major aimof this study was to understand the lateral and vertical variation in mineralogy, and the distribution of major andtrace elements within the different black shale lithologies, as well as in the overlying soils. The mobility of ...

This study investigates the leaching of main and trace elements from inorganic polymers made with an iron rich, fumed, > 90% amorphous slag. Different inorganic polymer binders were synthesized, varying the amount of the activating solution and the silica over sodium oxide ratio from 1.6, to 1.8, to 2.0, with constant water content of ±63%. Cascade and column leaching tests were performed in combination with geochemical speciation modeling ...

ABSTRACTSoil contamination poses a global problem. To address this a lot of scientific progress has been made. However, the development of the economic aspect has been lacking even though the total cost of soil remediation in Europe is estimated to be 119 billion euro. Frameworks and tools are available (for example SuRF-UK frame- work) to address economic aspects of soil remediation, but an established set of well-defined indicators is ...

The choice between remediation alternatives for contaminated sites is complicated by different elements, e.g., the occurrence of multiple contaminants, the extent of the contamination, or the urban location, complicate the choice between remediation alternatives. This paper addresses this challenging choice by analyzing a case study of an extensive soil and groundwater contamination by a dry-cleaning company. For remediating this site, two ...

Can Gio district is located in the coastal area of Ho ChiMinh City, southern Vietnam. Discharge of wastewater from Ho Chi Minh City and neighboring provinces to the rivers of Can Gio has led to concerns about the accumulation of trace metals (As, Cu, Cr, Ni, Pb, and Zn) in the coastal sediments. The main objective of this study was to assess the distribution of As, Cu, Cr, Ni, Pb, and Zn in surface and core sediments and to evaluate the ...
