Investigation on the Behavior of Pesticides in Atmosphere
Pesticides XAD-2 adsorbent GC analysis Atmosphere Air quality
2016/3/28
Although pesticides are widely used in agriculture, they and in particular the relative residues in foodstuffs, water and
atmosphere, may cause remarkable sanitary problems due to the harmful effects...
Deep Investigation of Ultrafine Particles in Urban Air
Ultrafine particles Energy Filtered Transmission Electron Microscope analysis Health effects Urban air Carbonaceous aeroso
2016/3/28
This work describes the results of a study which started in 2007 to investigate the ultrafine particle (UFP) pollution in
the urban area of Rome. The sampling site was located in a street with high d...
Soot microphysical effects on liquid clouds, a multi-model investigation
carbonaceous aerosols liquid clouds a multi-model investigation
2011/2/25
We use global models to explore the microphysical effects of carbonaceous aerosols on liquid clouds. Although absorption of solar radiation by soot warms the atmosphere, soot may cause climate cooling...
Investigation of the sources and processing of organic aerosol over the Central Mexican Plateau from aircraft measurements during MILAGRO
organic aerosol the Central Mexican Plateau aircraft measurements MILAGRO
2010/8/13
Organic aerosol (OA) represents approximately half of the submicron aerosol in Mexico City and the Central Mexican Plateau. This study uses the high time resolution measurements performed onboard the ...
An investigation of the origins of reactive gaseous mercury in the Mediterranean marine boundary layer
reactive gaseous mercury the Mediterranean marine boundary layer
2010/8/12
Atmospheric mercury species concentrations were measured during two oceanographic cruise campaigns covering the Adriatic Sea, the first during the autumn in 2004 and the second in the summer of 2005. ...
Investigation of ship-plume chemistry using a newly-developed photochemical/dynamic ship-plume model
ship-plume chemistry newly-developed photochemical/dynamic ship-plume model
2009/10/13
A photochemical/dynamic ship-plume model, which can consider the ship-plume dynamics and ship-plume chemistry, simultaneously, was developed to gain a better understanding of atmospheric impact of shi...
Laboratory investigation of photochemical oxidation of organic aerosol from wood fires 1: measurement and simulation of organic aerosol evolution
photochemical oxidation organic aerosol wood fires organic aerosol evolution
2009/3/13
Experiments were conducted to investigate the effects of photo-oxidation on organic aerosol (OA) emissions from flaming and smoldering hard- and soft-wood fires under plume-like conditions. This was d...
An investigation of ozone and planetary boundary layer dynamics over the complex topography of Grenoble combining measurements and modeling
ozone planetary boundary layer dynamics complex topography Grenoble combining measurements
2009/3/10
This paper concerns an evaluation of ozone (O3) and planetary boundary layer (PBL) dynamics over the complex topography of the Grenoble region through a combination of measurements and mesoscale model...
An investigation of processes controlling the evolution of the boundary layer aerosol size distribution properties at the Swedish background station Aspvreten
processes controlling boundary layer aerosol size distribution properties Swedish background station Aspvreten
2009/3/10
Aerosol size distributions have been measured at the Swedish background station Aspvreten (58.8° N, 17.4° E). Different states of the aerosol were determined using a novel application of cluster analy...
