In 2005, the European Commission funded NORMAN project to promote a permanent network of reference laboratories and research centers, including academia, industry, standardization bodies, NGOs. Since then, has (i) facilitated more rapid wide-scope exchange data on occurrence effects contaminants emerging concern (CECs), (ii) improved quality comparability via validation harmonization common sampling measurement methods (chemical biological), (iii) provided transparent information monitoring...

Abstract Biological effects are not related to the total concentration of a contaminant in soil and soil‐like materials. Organisms respond only fraction that is biologically available. The bioavailable fractions contaminants dependent on properties various processes varying with time behavior or target organism. Bioavailability may be assessed two complementary ways: (i) by chemical methods (e.g., extraction methods), which determine defined available well class contaminants; (ii) biological...
Soil is a key compartment for climate regulation as source of greenhouse gases (GHGs) emissions and sink carbon. Thus, soil carbon sequestration strategies should be considered alongside reduction other gas emissions. Taking this into account, several international European policies on change are now acknowledging the importance soils, which means that proper, comparable reliable information needed to report stocks GHGs from soil. It also implies need consensus adoption verification...
Biodegradation of polycyclic aromatic hydrocarbons (PAHs) and total petroleum (TPH) in sediment soil has been monitored on seven experimental fields during periods up to 25 years. With this unique dataset, we investigated long-term very slow biodegradation under field conditions. . The data show that three rates can be distinguished for PAHs: 1) rapid degradation the first year, 2) following 6 years 3), subject paper, a after 7 until at least Beside 2-, 3- 4-ring PAHs, also 5- 6-ring PAHs...
When applying landfarming for the remediation of contaminated soil and sediment, a fraction soil-bound contaminant is rapidly degraded; however, residual concentration may remain, which slowly degrades. Degradation polycyclic aromatic hydrocarbons (PAHs) mineral oil can be described using multi-compartment model first-order kinetics, in three degradable fractions are distinguished; (1) rapid, (2) slowly, (3) very degradable. Using this populated with data from long-term experiments...
Sediment−-water fluxes of hydrophobic organic chemicals (HOC) may affect the quality surface waters. Here, we present an approach to derive such from (a) in situ HOC concentration gradients measured with passive samplers and (b) mass transfer coefficients a novel flux method using Empore disks. For eight undisturbed sediments, this identified whether sediment acted as source or sink for HOCs. The analysis also which type transport resistance governed water exchange. seven inland locations,...
The consequences of permanent inundation and storage flood plain soils aquatic sediments on metal mobility were studied. main goal was to quantify kinetic mobilisation processes in order pinpoint the conditions that pose emission risks groundwater surface waters. Anaerobic pore water compositions six existing depots, containing from either or terrestrial origin, measured obtain reliable field references. Reduction experiments performed with SOFIE cells, which time-dynamic measurements...
The purpose of this study was to provide data be used in Netherlands for development ecotoxicologically based quality criteria oil-contaminated sediments and dredged material. In addition, the relation toxicity specific oil boiling-point fraction ranges explored. Natural marine sediment, with a moisture, organic carbon, silt content approximately 80, 1.8, 33% dry weight, respectively, artificially spiked using spiking method developed project. Aliquots one part sediment were several...
A potential for synergy exists between organic waste recycling, biomass production and long-term risk management contaminated land, particularly where the immediate economic case reuse of land is marginal. The possibility income generation from activities offers scope regeneration useful sustainable activity on such marginal land. It also an alternative use to `hard' redevelopment, as well a means facilitating topography or extent surrounding brownfield inhibits inward investment key site...
Abstract Various modes of Shpol'skii spectroscopy have been employed to directly determine a number isomeric four six-membered ring polycyclic aromatic hydrocarbons (PAHs) in crude extracts soil and sediment samples with different levels pollution. The high selectivity conventional (lamp excitation-fluorescence phosphorescence detection) enabled besides several priority PAHs, unambiguous identification individual monomethylpyrenes, five- PAH isomers. For 10 μ J.1 sample volume, the absolute...
Abstract Background Discussion concerning the bioavailability and ecotoxicological relevance of non-extractable residues (NER) in soil is still ongoing. Is NER formation a detoxification process or hidden hazard? The use radiolabelled chemicals enables detection NER, but identity usually unknown. Regulations require clear measurable parameters approach Ortega-Calvo et al. (Environ Sci Technol 49:10255–10264, 2015) defines these. Results Following that approach, we studied fate three...
