The ozone-climate penalty over South America and Africa by 2100
...
Climate change has the potential to increase surface ozone (O-3) concentrations, known as the "ozone-climate penalty", through changes to atmospheric chemistry, transport and dry deposition. In the tropics, the response of surface O-3 to changing climate is relatively understudied but has important consequences for air pollution and human and ecosy...
Metal particle seeding on urban surface samples
In order to estimate the resuspension of the particles empirically, it is necessary to carry out a homogeneous distribution of the particles on the tested surfaces. Thus, in many studies, seeding or deposition in experimental chambers is performed to quantify initial concentrations for subsequent resuspension experiments. The current study was carr...
Impact of tree species diversity on throughfall deposition in a young temperate forest plantation
Throughfall deposition is an important pathway via which particles, aerosols and gases can move from the atmosphere to the forest floor, which can greatly impact forest biodiversity and functioning. Although throughfall deposition biochem-istry has been well studied in forest ecosystems, less is known about how throughfall deposition is modified by...
Étude de la remise en suspension de polluants en milieu urbain
Ce travail s'est intéressé à la remise en suspension de particules métalliques (PM2.5) dans un contexte de milieu urbain. Il s'est agi d'estimer la part de particules ré-entrainées dans l'air sous l'effet de paramètres météorologiques et pour des surfaces représentatives de milieux urbains. Dans ce but, des éprouvettes de surfaces de bâti (ardoise,...
Platinum group elements in atmospheric PM10 particles and dry deposition in France.
Published in Environmental science and pollution research international
Platinum group elements (PGEs, i.e. platinum, Pt; palladium, Pd; and rhodium, Rh) catalyse over 90% of carbon monoxide, nitrogen oxides and hydrocarbons from combustion residues into water vapour, carbon dioxide and nitrogen in the vehicle's catalytic converter. But there is a major concern over these metals in the scientific world, since they are ...
Three-dimensional volumetric monitoring of settling particulate matters on a leaf using digital in-line holographic micr...
Plants are considered as a possible modality to reduce particulate matter (PM) particles from ambient air in an ecofriendly manner. A new precise monitoring technique that can explore interactions between individual PM particles and a leaf surface is necessary to understand the underlying mechanisms of PM removal of plant leaves. In this study, a d...

Atmospheric deposition of elements and its relevance for nutrient budgets of tropical forests
...
Atmospheric deposition is an important component of the nutrient cycles of terrestrial ecosystems, but field measurements are especially scarce in tropical regions. In this study we analysed 15 months of precipitation chemistry collected in an old growth tropical forest located in French Guiana. We measured nutrient inputs via bulk precipitation an...
High fire-derived nitrogen deposition on central African forests.
...Published in Proceedings of the National Academy of Sciences of the United States of America
Atmospheric nitrogen (N) deposition is an important determinant of N availability for natural ecosystems worldwide. Increased anthropogenic N deposition shifts the stoichiometric equilibrium of ecosystems, with direct and indirect impacts on ecosystem functioning and biogeochemical cycles. Current simulation data suggest that remote tropical forest...
