Abstract. Due to the major role of sun in heating earth's surface, atmospheric planetary boundary layer over land is inherently marked by a diurnal cycle. The afternoon transition, period day that connects daytime dry convective night-time stable layer, still has number unanswered scientific questions. This phase cycle challenging from both modelling and observational perspectives: it transitory, most forcings are small or null turbulence regime changes fully convective, close homogeneous...
The mixing state of aerosols collected at M'Bour, Senegal, during the Special Observing Period conducted in January–February 2006 (SOP‐0) African Monsoon Multidisciplinary Analysis project (AMMA), was studied by individual particle analysis. sampling location on Atlantic coast is particularly adapted for studying tropospheric since it (1) located path Saharan dust plumes transported westward over northern tropical Atlantic, (2) influenced biomass burning events frequent from December to...
Abstract. The large-scale emissions of airborne particulates from burning agricultural residues particularly over the upper Indo-Gangetic Plain (IGP) have often been associated with frequent formation haze, adverse health impacts, and modification in aerosol climatology thereby impact on regional climate. In this study, short-term variations during extreme biomass IGP were investigated. Size-segregated particulate concentration was initially measured submicron particles (PM1.1) found to...
The development of nanotechnologies is leading to greater abundance engineered nanoparticles (EN) in the environment, including atmospheric air. To date, it has been shown that most prevalent EN found air are silver (Ag), titanium dioxide (TiO2), (Ti), and silicon (SiO2). As intestinal tract increasingly recognized as a target for adverse effects induced by inhalation particles, aim this study was assess impact these 4 on inflammation microbiota. We assessed combined toxicity Ag, Ti, TiO2,...
More than a thousand Doppler lidars are already deployed in the world for wind energy or airport safety applications. Although such instruments optimized measurements, if they could also be qualified aerosol observations, would provide cheap and immediately accessible large database, which open perspectives pollutant dispersion studies. A scanning lidar was 8 months Dunkerque, 200,000 inhabitants harbor city northern France. The performed horizontal scans to acquire collocated observations...
Atmospheric aerosols consist of a complex heterogeneous mixture particles. Single-particle analysis techniques are known to provide unique information on the size-resolved chemical composition aerosols. A scanning electron microscope (SEM) combined with thin-window energy-dispersive X-ray (EDX) detector enables morphological and elemental single particles down 0.1 microm detection limit 1-10 wt %, low-Z elements included. To obtain data statistically representative air masses sampled,...
Fine particles were sampled both inside the chimneys and in near-field of an Fe–Mn-alloy manufacturing plant. The transfer from one point to another environment, as well bioavailability toxicity these two metals, depend above all on their speciation. oxidation states iron manganese collected determined by using transmission electron microscopy coupled with energy-loss spectroscopy (TEM-EELS). mineralogical identity metal-rich was selected area diffraction (SAED) energy-dispersive X-ray...
Sea breeze (SB) phenomena may strongly influence air quality and lead to important effects on human health. In order study the impact of SB dynamics properties toxicity aerosols, an atmospheric mobile unit was deployed during a field campaign performed in urbanized industrialized coastal area Northern France. This combines aerosol samplers, two scanning lidars (Doppler elastic) air-liquid interface (ALI, Vitrocell®) vitro cell exposure device. Our highlights that after passage front, top...
The Fe distribution in African dust particles collected Senegal (North‐Western Africa) during the Monsoon Multidisciplinary Analysis Special Observation Period 0 (AMMA‐“SOP 0,” February 2006) was assessed using individual particle analysis (Scanning and Transmission Electron Microscopy respectively equipped with X‐ray Spectrometry (SEM‐EDX) Energy Loss (TEM‐EELS)). is not a source area; chemical composition of dusts indicates that they originate primarily North‐Western Sahara, which...
