“…In the period 1880–1974, four zinc-ore smelters (three in Belgium, one in the Netherlands) emitted large amounts of heavy metals, such as Cd and Zn. Atmospheric deposition resulted in high and widespread accumulation of these metals in the upper soil layers surrounding the smelters (Van der Grift and Griffioen 2008 ; Bonten et al 2012 ). In addition, ore slags from these smelters were used to pave roads and gardens, resulting in leaching of Cd and Zn from these roads to groundwater (Copius Peereboom-Stegeman and Peereboom 1989 ; Bonten et al 2012 ).…”

“…When introduced into the environment, heavy metals tend to accumulate in soils and sediments (Foster and Charlesworth 1996 ) because of their affinity for sorption processes. Therefore, it may take decades to centuries or longer before heavy metals leach to groundwater (Seuntjens 2002 ; Degryse and Smolders 2006 ; Bonten et al 2012 ; Joris et al 2014 ). The solid-solution partitioning in soils is controlled by pH, redox potential, clay and soil organic matter (SOM) content, and the concentration of complex organic or inorganic ligands and competing cations (Elliott 1986 ; Hornburg and Brümmer 1993 ; Sauvé et al 2000 ; Römkens et al 2004 ; Pédrot et al 2008 ; Unamuno et al 2009 ; Degryse et al 2009 ; Acosta et al 2011 ; Groenenberg et al 2012 ).…”

“…This happens in particular when the precipitation intensity exceeds the infiltration capacity of soils or when soils are saturated (Smith and Goodrich 2006 ). Due to large accumulation of metals present in upper soil layers, metal concentrations are generally higher in water discharging to surface waters under quickflow conditions (Rozemeijer and Broers 2007 ; Bonten et al 2012 ).…”

This study investigates the impact of future climate change on heavy metal (i.e., Cd and Zn) transport from soils to surface waters in a contaminated lowland catchment. The WALRUS hydrological model is employed in a semi-distributed manner to simulate current and future hydrological fluxes in the Dommel catchment in the Netherlands. The model is forced with climate change projections and the simulated fluxes are used as input to a metal transport model that simulates heavy metal concentrations and loads in quickflow and baseflow pathways. Metal transport is simulated under baseline climate (“2000–2010”) and future climate (“2090–2099”) conditions including scenarios for no climate change and climate change. The outcomes show an increase in Cd and Zn loads and the mean flux-weighted Cd and Zn concentrations in the discharged runoff, which is attributed to breakthrough of heavy metals from the soil system. Due to climate change, runoff enhances and leaching is accelerated, resulting in enhanced Cd and Zn loads. Mean flux-weighted concentrations in the discharged runoff increase during early summer and decrease during late summer and early autumn under the most extreme scenario of climate change. The results of this study provide improved understanding on the processes responsible for future changes in heavy metal contamination in lowland catchments.

“…Even though leaching may not be equally relevant in all agro-ecosystems, in areas with high groundwater tables leaching of metals from soil to ground-and surface waters is one of the major pathways by which metals are released into the environment. Model studies by Moolenaar and Lexmond (1998) and Bonten et al (2012) for the Netherlands indicate that leaching makes up for 70% of the total Cd outputs from soil (aside from crop off-take). Estimates at EU level (Six and Smolders, 2014) even suggest that leaching losses are equal to more than 90% of the total Cd output from soil.…”

Impact of cadmium levels in fertilisers on cadmium accumulation in soil and uptake by food crops

Vries, 2018. Impact of cadmium levels in fertilisers on cadmium accumulation in soil and uptake by food crops. Wageningen, Wageningen Environmental Research, Report 2889. 116 pp.; 23 fig.; 60 tab.; 80 ref. Cadmium (Cd) and other heavy metals (lead (Pb), arsenic (As), chromium (Cr) and zinc (Zn)) occur naturally in fertilisers but at variable levels. To determine whether or not levels of metals in fertiliser affect the absorption of Cd and other metals by agricultural crops, a greenhouse study was performed to measure the uptake of Cd and other metals from 7 different soils grounds treated with either mineral fertiliser with increasing levels of Cd and one type of animal manure (cattle manure). The results show that there is no significant difference in absorption of Cd nor on other metals when P fertiliser is used with levels of Cd varying between 0.04 and 60 mg Cd kg -1 P 2 O 5 . Differences in soil properties (e.g. acidity and organic matter content) in combination with the content of Cd in the soil control the short term (1 harvest cycle) variation of Cd concentrations in crops. Long-term (100 years) calculations on a field and regional scale, however, show that the content of Cd in P fertilisers does affect both levels in soil and that in crops. Dynamic model simulations at EU level indicate that accumulation of Cd in soil (arable and grassland) continues if the Cd content in P fertilisers exceeds 20 mg Cd kg -1 P 2 O 5 . The calculated average long-term relative changes in both soil and arable crops relative to current levels are in the order of magnitude of +0.2% if no more Cd is applied via P fertiliser to 12.1% to 16% if, at the European level the concentration of Cd in mineral P-fertilisers averages 60 or 80 mg Cd kg -1 P 2 O 5 respectively. Cadmium (Cd) en andere zware metalen (lood (Pb), arseen (As), chroom (Cr) en zink (Zn)) komen van nature voor in kunstmeststoffen, maar in variabele gehalten. Om na te gaan of het gehalte aan metalen in kunstmest de opname van Cd en andere metalen door landbouwgewassen beïnvloedt, is in een kasopstelling de opname van Cd en andere metalen bepaald uit 7 gronden behandeld met kunstmest of rundermest met oplopende gehalten aan Cd. De resultaten tonen aan dat er geen significant verschil in opname van Cd van noch andere metalen is wanneer P kunstmest gebruikt wordt met gehalten aan Cd die variëren tussen 0,04 en 60 mg Cd kg -1 P 2 O 5 . Verschillen in bodemeigenschappen (zuurgraad en organische stof gehalte) in combinatie met het initiële gehalte aan Cd in de bodem zijn op korte termijn (1 oogstcyclus) bepalend voor de variatie in de gehalten aan Cd in gewassen. Lange termijn berekeningen op veld-en regionale schaal tonen aan dat het gehalte aan Cd in P kunstmeststoffen wel van invloed is op zowel het gehalte in de bodem als dat in gewassen. Op regionale schaal is berekend dat accumulatie van Cd in de bodem in de EU (akkerbouw en grasland) gemiddeld genomen doorgaat indien het Cd gehalte in P kunstmeststoffen hoger is dan 20 mg Cd kg -1 P 2 O 5 . De berekende gemid...

“…These methods are termed stochastic and deterministic [1][2][3]. Stochastic methods deal with reaction coefficients and are considered to 'be stationary processes' [1,[4][5][6][7][8][9][10], or they may be verified through a random hydraulic conductivity field [1,11,12]. As proper site-specific quantities are fundamental for simulation of contaminant transport, these models are expensive and unlikely to be used in practical cases [1].…”

The transport of contaminants has been a problematic issue for many years, mainly due to the adverse impact of the contaminants on the quality of groundwater. In order to analyse this, this study has developed a prediction model that allows the early detection of possible contamination. Firstly, the paper introduces the concept of the modelling of contamination transport through a soil matrix. Then it presents a two-dimensional Convection-Dispersion Equation (CDE) for contaminant transport in a soil matrix. This includes the investigation of different reaction coefficients and time-dependent inlet boundary conditions, from which a numerical solution is derived. The study also verifies recent previous work in this area through the use of numerical programming. The results for soil contamination in two dimensions are presented in this research.
