Study of atmospheric dispersion under low wind conditions in an urban environment

Autor: Hanane Bounouas, Pierre Roupsard, Eric Dupont, Yannick Lefranc, Aurélien Faucheux, Didier Hebert, Olivier Connan, Philippe Languionie, Yelva Roustan

Impact studies of industrial sites for air pollutant emissions must consider all representative meteorological conditions. For low wind conditions, the impact evaluations present large uncertainties. Dispersion mechanisms and turbulence properties in

Journal of Aerosol Science, 2018, 126, pp.58-67. ⟨10.1016/j.jaerosci.2018.08.004⟩

International audience; Aerosols emitted into the atmosphere are dispersed by atmospheric air masses and then removed by dry or wet deposition processes. In some cases, if there are no episodes of precipitation, dry deposition may be the main process

A New Method for Assessing the Contribution of Atmospheric Deposition to the Stormwater Runoff Metal Load in a Small Urban Catchment

Autor: Maurice Millet, Pierre Roupsard, Véronique Ruban, Stéphane Percot, Denis Maro

Publikováno v: Water, Air, & Soil Pollution. 227

The contribution of atmospheric deposition to the metal load at the outlet of a small urban catchment (Pin Sec, France) was studied. A new method taking into account the nature of urban surfaces (glass, tile, bitumen, zinc sheet, grass, facade coatin

International audience; Atmospheric transport plays an important role in the transfer of pollutants to ecosystems. During such transport, the atmospheric aerosol is one of the key factors in terms of deposition. Over 18 months, we studied the concent

Atmospheric environment, Elsevier, 2013, 74, pp. 338-345. ⟨10.1016/j.atmosenv.2013.03.056⟩

The aerodynamic size distribution of the natural radionuclide Beryllium 7 (7Be) and associated trace metals, pesticides and polycyclic aromatic hydrocarbons (PAHs) in Nantes (France) was determined during 6 campaigns (conducted from June 2010 to Marc

The objective here is to characterize atmospheric deposition in a small urban catchment. Our results show that micro pollutant concentrations are very low. Polycyclic aromatic hydrocarbons are only detected during the winter, while pesticides are det
