abstract = {Dredging and disposal of sediments onto land sites is a common practice 

	in urban and industrial areas that can present environmental and 

	health risks when the sediments contain metallic elements. The aim 

	of this study was to characterise and study the environmental and 

	toxicological availability of Cd and Pb in anthroposols from dredged 

	river sediments. To do this, 67 surface samples spread over 12 sediment 

	disposal sites in northern France were studied. The results showed 

	substantial heterogeneity for this matrix in terms of physicochemical 

	parameters and contamination degree; however, ascending hierarchical 

	clustering made it possible to classify the samples into eight groups. 

	For each group, the mobile fraction of Cd and Pb was studied using 

	single EDTA extraction, solid-phase distribution was analysed with 

	sequential extractions and toxicological availability was assessed 

	with the oral bioaccessibility test. The results showed that (i) 

	Cd had a higher environmental and toxicological availability than 

	Pb; (ii) this availability depends on the physicochemical characteristics 

	of the matrix; and (iii) it is necessary to take into account the 

	environmental and toxicological availability of contaminants when 

	requalifying these sites in order to propose appropriate management 

	measures. In the first years after sediment disposal, it would appear 

	that the environmental and toxicological availability of Cd and Pb 

	increased (from 52.5 to 71.8% and from 28.9 to 48.9%, respectively, 

	by using EDTA and from 50.2 to 68.5% for Cd with the bioaccessibility 

	test). Further studies would therefore be required to confirm this 

	trend and understand the mechanisms involved.},

abstract = {During the last few decades, stormwater ponds have become an alternative 

	management practice in order to avoid flooding and to contain rainwater 

	and runoff in urban areas where impervious land cover has increased. 

	A second purpose of stormwater ponds is to improve the quality of 

	runoff water that is usually contaminated with nitrogen, phosphorus, 

	metals and organic micropollutants. Processes used are based on natural 

	methods such as settlement and contribute to minimize the impact 

	of these inputs to the natural aquatic system. This study aims to 

	better understand the behavior of a wet stormwater pond, Heron Lake 

	(33 ha) located in the city of Villeneuve d’Ascq in northern France 

	through various indicators [trace metals, PAHs, PCBs, caffeine (CAF), 

	carbamazepine (CBZ), nutrients and pathogens]. For that purpose, 

	water quality was monitored for 1 year, mainly at the entrance and 

	at the outlet of the lake. Sampling have also been done in the downstream 

	aquatic environment, the Marque River. Sediments were sampled in 

	the lake to evaluate the pollution trapped during sedimentation. 

	Our results of both water and sediment sampling highlight: (i) the 

	wastewater input into the Heron Lake is estimated to be equivalent 

	to that of roughly 3800 inhabitants; (ii) the removal rates observed 

	at the outlet, relative to concentrations at the entrance channel, 

	vary as follows for these dissolved species: 24% for NO3− and PO43−, 

	28% for CBZ, 35% for Cu, 63% for Pb, 78% for CAF, 84% for Zn and 

	up to 93% for NH4+; (iii) there are high levels of sediment contamination 

	with metals, PAHs and PCBs at the entrance channel; (iv) the eutrophication 

	of this pond is attributed to persistent high nutrient concentrations 

	in both water and sediment, and has contributed to the development 

	of an invasive macrophyte, the Elodea nuttallii; and (v) there appears 

	to be only a negligible impact of the discharge from the lake to 

	the natural watercourse, contributing annual loads of <2 up to 6% 

	of the total amount of Cu, Pb, Zn, CAF, CBZ and nutrients measured 

	in the Marque River, and having a slight diluting effect on concentrations 

	in the Marque River.},

It employs a strip of polyethylene deployed as a passive sampler. Verifications are confirmed via conventional spot sample analyses and against Performance Reference Compound (PRC) calibration methods. Analytes targeted include 16 Polycyclic Aromatic Hydrocarbons, 15 personal care products, 8 organophosphorus flame retardants, 4 antifouling ‘booster’ biocides and 15 n-alkanes. Whilst all contaminants typically revealed homogeneous concentrations from 10 cm to 3 m depth in the selected harbour (< 30% variations), many increased sharply at the air-sea interface. The passive sampler was shown to afford better resolution than could be achieved using conventional analytical techniques	at the surface microlayer (SML). Whilst hydrophobicity appeared to be a key factor for the enrichment of many determinants, less correlation was found for the emerging contaminants.},

abstract = {A passive sampler inspired from previous devices was developed for the integrative sampling of a broad range of contaminants in the	water column. Our primary objective was to improve the performance of the device to provide accurate and averaged pollutant water concentrations. For this purpose, an agarose diffusive gel was used as the boundary layer that drives the analyte uptake rate. Contrary to conventional passive samplers, the developed device does not require the sampling rates to be corrected for exposure conditions (e.g. hydrodynamic flow) because the diffusive gel boundary layer selected was sufficiently large to control the pollutant diffusion rate from the aqueous phase. The compounds diffusion coefficients in agarose gel and the gel thickness are the only required data to accurately calculate the time weighted averaged water concentration of pollutants. The performance of the developed sampler was evaluated in the laboratory under two contamination scenarios and in the field in 8 contrasting exposure sites for a selection of 16 emerging pollutants and pesticides. The results show that detection limits of this method are environmentally relevant and allow the determination of the averaged pollutant concentrations. Additionally, the ability of the device to sense very short contamination pulses (5–320 min) was evaluated through a theoretical approach and laboratory tests. Results show that the device is suitable for sampling contamination pulses as short as 5 min without deviation from the actual average concentrations of pollutants.},

abstract = {A new method based on passive samplers has been developed to assess the diffusive flux of fluorene, fluoranthene and pyrene in the sediment bed and across the sediment-water interface. The dissolved compound concentration gradient in the sediment in the vertical direction was measured at the outlet of a storm water pond by using polyethylene strips as passive samplers. Simultaneously, the dissipation of a set of tracer compounds preloaded in the passive samplers was measured to estimate the effective diffusion coefficients of the pollutants in the sediment. Both measurements were used to evaluate the diffusive flux of the compounds according to Fick's first law. The diffusive fluxes of the 3 studied compounds have been estimated with a centimetre-scale resolution in the upper 44 cm of the sediment. According to the higher compound diffusion coefficient and the steeper concentration gradient in the surficial sediment layer, the results show that the net flux of compounds near the sediment interface (1 cm depth) is on average 500 times higher than in the deep sediment, with average fluxes at 1 cm depth on the order of 5, 0.1 and 0.1 ng/m2/y for fluorene, fluoranthene and pyrene, respectively.},

abstract = {In this paper, a method for evaluating the in-situ degradation of nitro polycyclic aromatic hydrocarbons (nitro-pah) in sediments is presented. the methodology is adapted from the passive sampler technique, which commonly uses the dissipation rate of labeled compounds loaded in passive sampler devices to sense the environmental conditions of exposure. in the present study, polymeric passive samplers (made of polyethylene strips) loaded with a set of labeled polycyclic aromatic hydrocarbons (pah) and nitro-pah were immersed in sediments (in field and laboratory conditions) to track the degradation processes. this approach is theoretically based on the fact that a degradation process induces a steeper concentration gradient of the labeled compounds in the surrounding sediment, thereby increasing their compound dissipation rates compared with their dissipation in abiotic conditions. postulating that the degradation magnitude is the same for the labeled compounds loaded in polyethylene strips and for their native homologs that are potentially present in the sediment, the field degradation of 3 nitro-pah (2-nitro-fluorene, 1-nitro-pyrene, 6-nitro-chrysene) was semi-quantitatively analyzed using the developed method.},

abstract = {In france, erosion by water run-off is estimated to 1.5 t ha-1yr-1 and can exceed 10 t ha-1yr-1 in large growing areas, such as the north of france (nord-pas-de-calais). in this region, the canche watershed (1294 km2) sustains heavy loss of fertile soils. the land use is mainly dominated by arable lands (80%) and in 2013, 104 kt of suspended sediment transited to the estuary. as demonstrated in literature, agricultural soil erosion leads to the gradual disappearance and depletion of fertile soil, which constitute a non-renewable resource at human time scale. additionally, water erosion can significantly damage the aquatic habitat and can be responsible for the input of nutrients, bacteria, pesticides, heavy metals and radionuclides into surface waters. conscious of these effects, many programs have emerged in the nord-pas-de-calais to reduce erosion. this study presents a combination of environmental magnetic proxy parameters and geochemical analyses on sediments and suspended particulate matter. the aim is to develop effective tools to trace erosion by water run-off and quantify this process. in order to identify the respective sediment sources in the canche watershed, sediment trap samples of suspended particulate matter were recovered at key positions along the canche watershed. the preliminary results show that magnetic concentration (mrs) shows typical values for the agricultural soils in the region, but these variations in magnetic concentrations and total irons concentrations are not always correlated, which may be explained by the iron speciation. in calculating the so-called s-ratio for each sample we can distinguish changes in magneto-mineralogy (and thus iron speciation) from magnetite-dominated assemblages in the mainstream canche (naturel background signal) to high-coercivity-dominated assemblages in the tributaries, typical for soil erosion material rich in hematite/goethite. in combination with the element concentrations from icp analyses, this proxy parameter may give valuable insight into the tracing of the suspended sediment sources. in perspective, the seasonal variability and the discharge in the canche watershed have to be taken into account.},

abstract = {Purpose Contamination of river sediment reaches problematic levels 

	in industrialised regions. This study investigates the relevance 

	of using beryllium-7 (7Be), a short-lived environmental radionuclide 

	(53 days half-life), for quantifying the deposition and resuspension 

	of sediment and associated metallic contaminants in a heavily polluted 

	channelized river of Northern France (The Lower Scarpe River). 

 

	Materials and methods Activities in 7Be were measured in bed and suspended 

	sediments collected each month over a hydrological year. Suspended 

	sediments were analysed for metal contents (Pb, Zn, Cd, Cu). The 

	determination of short-term sediment dynamics is based on the variation 

	of total 7Be inventory between two successive samplings. Total inventory 

	of 7Be consists of two components, i.e., the residual inventory and 

	the new inventory. 

 

	Results and discussion Inventories of 7Be in sediment varied from 

	1 to 135 mBq cm−2. Observed spatial and temporal variations reflected 

	the dynamic behaviour of sediment in the studied channel section. 

	The succession of sediment deposition and resuspension periods was 

	demonstrated during the study, with maximum deposition and erosion 

	rates of 0.3 ± 0.2 and −0.46 ± 0.05 g cm−2 month−1, respectively. 

	A sediment resuspension rate of 0.06 g cm−2 month−1 supplied to the 

	water column a flux of 12, 13, 23 and 145 μg cm−2 month−1 of Cd, 

	Cu, Pb and Zn, respectively. During this 15-month study, 28 to 50 

	% of Pb that was deposited in the riverbed sediment was resuspended, 

	thereby contributing to the (short term) degradation of water quality. 

 

	Conclusions The present work provides a useful tool for examining 

	the role of sediment as a sink or source of contamination for the 

	water column. It produces knowledge of how sediment processes affect 

	the fate and the transport of contaminants and the implications for 

	future downstream fluxes},

abstract = {A geological disposal in Gault clay (France) is planned for low activity,

	ensure both radioactive and hazardous chemical elements sequestration. 

	This study focused on As(V) and Cr(VI) retention on the Gault Clay 

	under different environmental storage conditions. A serie of batch 

	sorption tests were performed under oxic/anoxic conditions with various 

	composition of aqueous solutions. Experimental results were used 

	to develop and calibrate a surface complexation model using CHESS™ 

	and to improve our understanding of processes adsorption. Clay rock 

	sample caracterisation by XRD reveals a wide variety of minerals 

	as well as Quartz, Kaolinite, Illite, Goetite. Batchs results show 

	a high removal of As (77% in oxic conditions and 83% in anoxic conditions) 

	and the geochemical model suggest that sorption on iron oxides (Goetite) 

	is the principal process of As sequestration. The chemical environment 

	have an impact on As removal, especially in the presence of phosphates 

	which compete with As for iron oxides sorption sites. Low Cr removal 

	is observed in oxic conditions (9%) but the percentage rises to 47% 

	in anoxic ones. Sorption is a minor process and removal of Cr in 

	anoxic conditions can be explained by the reduction of hexavalent 

	chromium and precipitation of trivalent chromium (Cr2O3, MgCr2O4…). 

	Reduction of Cr(VI) is also very sensitive to acid pH. Thus the removal 

	of Cr at pH 4 in oxic conditions is close to 90 %. This research 

	revealed As and Cr behaviour in natural Gault clay sample, processes 

	of removal from garbage leachate and significance of chemistry environment 

	and thermodynamics conditions. Columns tests and simulations with 

	HYTECTM will be mained to understanding the transport mechanisms 

	of this pollutants.},
