Although runoff from trafficked urban areas is recognized as a potentially significant pathway of micropollutants, runoff pollution remains poorly documented, except for relatively few historical pollutants such as some metals and hydrocarbons. Therefore, in this work, road and parking lot runoff from four sites with contrasting traffic levels were...
Surfactants based on polyfluoroalkyl ethers are commonly used in fire-fighting foams on airport platforms, including for training sessions. Because of their persistence into the environment, their toxicity and their bioaccumulation, abnormal amounts can be found in ground and surface water following the operations of airport platforms. As with many...

The increasing international interest in contemporary architecture has drawn attention to the numerous listed buildings made of reinforced concrete in Europe, and especially in France. The main source of deterioration of this cultural heritage is the corrosion of rebars through carbonation or chloride contamination, but also often by a combination ...
Ce guide propose une démarche permettant d'évaluer le danger potentiel relatif aux sites d'accumulation de sédiments d'eau douce continentale (ouvrages et voies navigables), notamment en amont d'opérations d'entretien. Il est également adapté au diagnostic des causes de déclassement en mauvais état d'un site lors de suivi de qualité dans un context...
Une des pistes de recherche les plus récentes concernant la gestion des espèces végétales invasives porte sur les capacités des plantes à produire des composés chimiques inhibant la croissance ou le développement d'autres végétaux. Cet article décrit les enjeux, quelques recherches menées en France et les défis posés par cette démarche.
Strategies for measuring occupational exposure to aerosols composed of nanoparticles and/or ultrafine particles highlight the use of techniques for determining airborne-particle number concentration as well as number size distribution. The objective of the present work was to set up a system for conducting laboratory verification campaigns of conde...
The aim of this experimental study was to investigate the performance of both portable and transportable devices devoted to the real-time measurement of airborne particle number concentration and size (distribution). Electrical mobility spectrometers (SMPS, FMPS, Nanoscan) as well as diffusion chargers (DiSCmini, Nanotracer) were studied. Both mono...
The handling of carbon nanotube (CNT) powders is a plausible scenario during the course of the CNT life-cycle. However, related exposure data remain limited. In this context, information about the dustiness of CNT is therefore of great interest, for example for control banding or exposure modelling. Here, we investigate the dustiness of fourteen CN...
Les stratégies de mesure des expositions professionnelles aux aérosols de nanomatériaux mettent en avant l’utilisation de techniques de mesure de la concentration en nombre de particules ainsi que leur distribution granulométrique. L’objectif de ces travaux était de mettre en place un système de référence permettant de mener en laboratoire des camp...
