Airborne Investigations of Aerosol Particles from a Paper Mill

Inflammatory markers and exposure to airborne particles among workers in a Swedish pulp and paper mill

PURPOSE To study the relationship between exposure to airborne particles in a pulp and paper mill and markers of inflammation and coagulation in blood. METHODS Personal sampling of inhalable dust was performed for 72 subjects working in a Swedish pulp and paper mill. Stationary measurements were used to study concentrations of total dust, respirable dust, PM10 and PM2.5, the particle surface ...

A Miniature Aerosol Sensor for Detecting Polydisperse Airborne Ultrafine Particles

Counting and sizing of polydisperse airborne nanoparticles have attracted most attentions owing to increasing widespread presence of airborne engineered nanoparticles or ultrafine particles. Here we report a miniature aerosol sensor to detect particle size distribution of polydisperse ultrafine particles based on ion diffusion charging and electrical detection. The aerosol sensor comprises a co...

Measurements of Airborne Influenza Virus in Aerosol Particles from Human Coughs

Influenza is thought to be communicated from person to person by multiple pathways. However, the relative importance of different routes of influenza transmission is unclear. To better understand the potential for the airborne spread of influenza, we measured the amount and size of aerosol particles containing influenza virus that were produced by coughing. Subjects were recruited from patients...

Comprehensive airborne characterization of aerosol from a major bovine source

We report an extensive airborne characterization of aerosol downwind of a massive bovine source in the San Joaquin Valley (California) on two flights during July 2007. The Center for Interdisciplinary Remotely-Piloted Aircraft Studies (CIRPAS) Twin Otter probed chemical composition, particle size distribution, mixing state, suband supersaturated water uptake behavior, light scattering propertie...
