Gerardu, Th. (author), Dijkstra, J.J. (author), Beeltje, H. (author), van Renesse van Duivenbode, J.A.D. (author)PFOA and PFOS are widely found PFAS components in Dutch topsoils. PFOA was emitted to the atmosphere during 1970-2012 from a fluoropolymers factory, and was deposited mainly within a radius of 50 km. For the first time, detailed concentration-depth profiles of PFOA and PFOS were measured in undisturbed soils down wind of the factory. Three...article 2023

van Zomeren, A. (author), Koper, R. (author), Dijkstra, J.J. (author), Comans, R.N.J. (author)Analysis of dissolved organic carbon (DOC) is widely used to quantify the sum of organic carbon species in water. Analyzers based on wet chemical oxidation (WCO) usually have a relatively low detection limit (±1 μg of C/L) and are, therefore, well suited for analyses of DOC in environmental samples (e.g., surface water, groundwater, or seawater)...article 2021

(author), Griessacher, T. (author), Raith, J.G. (author), Pomberger, R. (author), Vollprecht, D. (author)In this study, possible leaching control mechanisms for Cr and V in electric arc furnace slags were investigated by using a multi-methodological approach. Aside from chemical and mineralogical bulk analyses, special emphasis was given to surface investigations of the slags prior to and after leaching. In addition, pH dependence leaching tests...article 2019

(author), Raith, J.G. (author)In waste management, recycled and industrial aggregates (e.g., electric arc furnace (EAF) slags) for construction applications have to fulfil the limit values with respect to the total and/or leachable contents of potentially environmentally problematic chemical elements (PEPE, e.g., Cr, Ni, Cu, Mo, V).

Dijkstra, J.J. (author), van Zomeren, A. (author)De stortbranche heeft in 2015 een zogenaamde Green deal afgesloten met het Ministerie van Infrastructuur en Milieu. Het doel is om te onderzoeken of het mogelijk is om de verontreinigingen in stortplaatsen versneld onschadelijk te maken door technische maatregelen zoals beluchting en doorspoeling. Als het experiment slaagt, dan is het mogelijk...report 2019

Keulen, A. (author), van Zomeren, A. (author), Dijkstra, J.J. (author)This study explores the leaching of oxyanionic metalloid species (As, Mo, Se, V and Cr) from alkali activated slag-fly ash materials (AAM), dependent on various mixture parameters i.e., activator molarity, slag-fly ash precursor/binder compositions, liquid to binder ratio, curing time and strength. The analyses focusses on the leaching of...article 2018

(author)The migration of radionuclides through the host rock plays an important role for the long-term safety of disposal concepts in Boom Clay. Due to the slow transport of radionuclides in the host rock, most radionuclides will be decayed before they can enter the surrounding aquifers. For many scenarios that will be considered in OPERA, the delayed...article 2017
