“…However, higher exposure is assumed in children and adolescents, reaching up to 3.4 µg/kg body weight daily (Vainio, 2003). The European Union has set a limit of 0.1 µg/L residual acrylamide in drinking water (Binet et al, 2015). Whereas FAO/WHO have agreed that the "no observed adverse effect level" (NOAEL) for acrylamide neuropathy is 0.5 mg/kg body weight/day, while that for fertility changes is four times higher than for peripheral neuropathy.…”

Acrylamide is a potential health hazardous compound occurring in baked and fried food as a result of excessive dry heating during the preparation and/or processing of foods. Exposure to a high level of acrylamide may cause cancer, neurotoxicity, and mutagenicity. In this study, an isocratic reversed-phase high-performance liquid chromatographic (HPLC) method using a C18 column was used for the determination of acrylamide in selected food. The mobile phase consisted of 0.1% formic acid in water: acetonitrile (98:02), and the flow rate was 1.0 mL min-1, elution was monitored at 200 nm. Validation in selected conditions showed that the chosen method is sensitive, selective, precise, and reproducible with a linear detector response for the determination of acrylamide. The limit of detection (LOD), and the limit of quantification (LOQ), were achieved at 0.41μg mL-1 and 1.25 μg mL-1respectively. The proposed method was also applied after validation to the most popular six brands of chips and French fries available in the Libyan market. Acrylamide was extracted by a simplified extraction method avoiding cleanup by solid-phase extraction (SPE), then analyzed by HPLC-UV. The highest level of acrylamide was found in one brand of chips with a concentration of 16.33 μg mL-1, whereas only one of the French fries products analyzed exhibited an acrylamide concentration of 10.26 μg mL-1.

INSU/CNRS national observatory of karstic aquifers, SNO KARST.International audienceSpecific vulnerability estimations for groundwater resources are usually geographic information system-based (GIS) methods that establish spatial qualitative indexes which determine the sensitivity to infiltration of surface contaminants, but with little validation of the working hypothesis. On the other hand, lumped parameter models, such as the Residence Time Distribution (RTD), are used to predict temporal water quality changes in drinking water supply, but the lumped parameters do not incorporate the spatial variability of the land cover and use. At the interface between these two approaches, a GIS tool was developed to estimate the lumped parameters from the vulnerability mapping dataset. In this method the temporal evolution of groundwater quality is linked to the vulnerability concept on the basis of equivalent lumped parameters that account for the spatially distributed hydrodynamic characteristics of the overall unsaturated and saturated flow nets feeding the drinking water supply. This vulnerability mapping method can be validated by field observations of water concentrations. A test for atrazine specific vulnerability of the Val d’Orléans karstic aquifer demonstrates the reliability of this approach for groundwater contamination assessment

Aggregate quarries play a major role in land settlement. However, like all industrial operations, they can have impacts on the environment, notably due to the use of polyacrylamide (PAM)-based flocculants, which contain residual acrylamide (AMD), a carcinogenic, mutagenic, and reprotoxic monomer. In this study, the dissemination of AMD throughout the environment has been investigated in a French quarry. The presence of AMD has been determined in the process water and in the sludge, as well as in the surrounding surface water and groundwater. From the results of several sampling campaigns carried out on this case study, we can (a) confirm that the AMD contained in the commercial product is found in the quarry's water circuit (0.41 to 5.66 μg/l); (b) show that AMD is transported to the surrounding environment, as confirmed by the contamination of a pond near the installation (0.07 to 0.08 μg/l) and the presence of AMD in groundwater (0.01 to 0.02 μg/l); and (c) show that the sludge in both the current and former settling basins contains AMD (between 4 and 26 μg/kg of dry sludge). Therefore, we demonstrated in this case study that using PAM-based flocculants leads to the release of AMD to the environment beyond the treatment plant and creates a reserve of AMD in sludge basins.
