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...
Modelling multi-phase halogen chemistry in the coastal marine boundary layer: investigation of the relative importance of local chemistry vs. long-range transport
multi-phase halogen chemistry the coastal marine boundary layer local chemistry long-range transport
2011/2/25
Measurements of significant concentrations of IO, I2 and BrO in a semi-polluted coast environment at Roscoff, in North-West France, have been made as part of the Reactive Halogens in the Marine Bounda...
Investigation of the correlation between odd oxygen and secondary organic aerosol in Mexico City and Houston
the correlation odd oxygen and secondary organic aerosol Mexico City Houston
2010/10/11
Many recent models underpredict secondary organic aerosol (SOA) particulate matter (PM) concentrations in polluted regions, indicating serious deficiencies in the models' chemical mechanisms and/or mi...
An investigation of the sub-grid variability of trace gases and aerosols for global climate modeling
the sub-grid variability trace gases and aerosols global climate modeling
2010/8/16
One fundamental property and limitation of grid based models is their inability to identify spatial details smaller than the grid cell size. While decades of work have gone into developing sub-grid tr...
Hygroscopic properties of Amazonian biomass burning and European background HULIS and investigation of their effects on surface tension with two models linking H-TDMA to CCNC data
Hygroscopic properties H-TDMA CCNC data surface tension
2010/8/13
HUmic-LIke Substances (HULIS) have been identified as major contributors to the organic carbon in atmospheric aerosol. The term "HULIS" is used to describe the organic material found in aerosol partic...
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. ...
An aerosol chamber investigation of the heterogeneous ice nucleating potential of refractory nanoparticles
aerosol chamber heterogeneous ice nucleating potential refractory nanoparticles
2010/2/21
All samples were observed to initiate ice formation via the deposition mode at threshold ice super-saturations (RHithresh) ranging from 105% to 140% for temperatures below 220 K. Approximately 10% of ...
An investigation of nucleation events in a coastal urban environment in the Southern Hemisphere

2009/11/9
Ambient aerosols play an important role in atmospheric processes affecting the human and natural environments. They affect air quality, reduce visibility, and induce climate change by directly scatter...
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...
Modelling multi-phase halogen chemistry in the remote marine boundary layer: investigation of the influence of aerosol size resolution on predicted gas- and condensed-phase chemistry
Modelling multi-phase halogen chemistry remote marine boundary layer aerosol size resolution
2009/7/22
