“…For example, the European Union System for the Evaluation of Substances (EUSES) was developed to address the need to determine the risk posed to human health and the environment of notified current-use and new substances. 1,2 This system relies on a regional distribution model based on the SimpleBox platform 3,4 to generate predicted environmental concentrations (PECs) in environmental compartments (e.g. air, water, sediment, soil) that can then serve as input to a human exposure model.…”

Empirical evaluation of spatial and non-spatial European-scale multimedia fate models: results and implications for chemical risk assessment

et al. 2007

Multimedia environmental fate models are commonly-applied tools for assessing the fate and distribution of contaminants in the environment. Owing to the large number of chemicals in use and the paucity of monitoring data, such models are often adopted as part of decision-support systems for chemical risk assessment. The purpose of this study was to evaluate the performance of three multimedia environmental fate models (spatially-and non-spatially-explicit) at a European scale. The assessment was conducted for four polycyclic aromatic hydrocarbons (PAHs) and hexachlorobenzene (HCB) and compared predicted and median observed concentrations using monitoring data collected for air, water, sediments and soils. Model performance in the air compartment was reasonable for all models included in the evaluation exercise as predicted concentrations were typically within a factor of 3 of the median observed concentrations. Furthermore, there was good correspondence between predictions and observations in regions that had elevated median observed concentrations for both spatiallyexplicit models. On the other hand, all three models consistently underestimated median observed concentrations in sediment and soil by 1-3 orders of magnitude. Although regions with elevated median observed concentrations in these environmental media were broadly identified by the spatially-explicit models, the magnitude of the discrepancy between predicted and median observed concentrations is of concern in the context of chemical risk assessment. These results were discussed in terms of factors influencing model performance such as the steady-state assumption, inaccuracies in emission estimates and the representativeness of monitoring data.

“…Concentrations of many compounds exceed quality standards at many locations (Japenga et al, 1990;Hendriks et al, 1995;Gocht et al, 2001). Even if pollutant concentrations in river water decrease, there is still accumulation in the soil (Japenga & Salomons, 1993;Leuven et al, 2005;Hollander et al, 2006;Wijnhoven et al, 2006). Although the concentrations of most contaminants in the river water have substantially decreased during the last decades, floodplain soils may still contain high concentrations of persistent contaminants that can accumulate at different trophic levels (e.g., Hendriks & Pieters, 1993;Goodyear & McNeill, 1999).…”

Biogeochemical Constraints on the Ecological Rehabilitation of Wetland Vegetation in River Floodplains

et al. 2006

The European policy for river management during peak discharge periods is currently changing from exclusion strategies (reinforcement of dykes) to allowing a more natural situation by creating more floodplain space to reduce water levels during peak discharges. In addition, water retention and water storage areas have been created. The new measures are generally being combined with nature development strategies. Up till now, however, ecological targets of broadscale floodplain wetland restoration including sedge marshes, species-rich floodplain forests and carrs, riparian mesotrophic grasslands and other biodiverse riverine ecosystems, have hardly developed in these areas. Most studies on the conditions needed for sustainable ecological development of floodplains have focused on hydrological and geomorphological rather than biogeochemical issues (including nutrient availability and limitation). There are, however, large differences in the composition of river water and groundwater and in sediment quality between rivers in densely populated areas and those in more pristine areas, which serve as a reference. It is very likely that these factors, in combination with heavily altered hydrological regimes and the narrow areas confined between the dykes on both sides of the rivers, impose major constraints on sustainable ecological development of riverine areas. Another issue is that existing wetlands are generally considered to be very appropriate for water retention and conservation, although recent research has shown that this may pose a serious threat to their biodiversity. The present paper reviews the biogeochemical constraints on the combination of floodplain rehabilitation, water conservation and the conservation and development of wetlands. It is concluded that biogeochemical problems (mainly related to eutrophication) predominantly arise in less dynamic parts of the river system, to which the flood-pulse concept applies less. Sound knowledge of the biogeochemical processes involved will contribute to greater efficiency and a better prediction of the opportunities for restoration and development of riverine wetlands. This information can be directly applied in nature management, water management, policy-making and consultancy. Changing concepts, changing riversDuring peak discharge periods, regulated river systems in densely populated areas such as the Netherlands have to cope with excessive volumes of water in a narrow area confined by dykes. In the past, the only strategy was to avoid flooding by raising and reinforcing dykes (levees). Since this

“…It is very clear from these concepts, which are tools to understand natural processes and their impacts on ecosystem functioning, that processes upstream influence processes downstream and vice versa. Calculations with the Basin Box multimedia fate model show that spatial differences between upstream, midstream and downstream areas of large river basins may have a considerable impact on the environmental concentrations of chemicals (Hollander et al, 2006). Other examples are migration of fish species and natural damming, e.g.…”

This paper discusses and summarizes the major conclusions of the special issue entitled 'Living rivers: trends and challenges in science and management' of Hydrobiologia/Developments in Hydrobiology. It is structured along three lines: (1) Functioning of river systems; (2) Ecological rehabilitation of river systems;(3) Challenges and obstacles to sustainable management. Sustainable river basin management requires a thorough understanding of natural, physical, chemical and ecological processes as well as socio-economic functioning. Environmental rehabilitation of river systems inevitably requires an ecosystem-based approach involving solutions supported by the public. The challenge is to combine ecological and socioeconomic sustainability. Rethinking our efforts in both directions must lead to more innovative solutions than those available at present.
