Pollution Characteristics Revealed by Size Distribution Properties of Aerosol Particles at Urban and Suburban Sites, Northwest China

High temporal resolution (5 min) particle size distribution data (0.5‒20 μm) were collected using aerodynamic particle sizer at an urban (Lanzhou) and a suburban (Yuzhong) site at Lanzhou, northwest China from 1 August to 31 October 2010. Variations of particle concentrations and properties of volume size distributions (PVSD) were analyzed and urban pollution characteristics were investigated u...

Platanus hispanica Aeroallergen in Northwest Spain

Background and Objective: Platanus hispanica trees are considered an important source of airborne pollen allergens in many cities of Western Europe. As the prevalence of sensitization to this species is 8% to 9% in northwestern Spain, our objective was to propose models predicting both the onset of the pollen season and the mean daily pollen concentrations. Methods: Airborne P hispanica pollen ...

Real-Time Determination of Absorptivity of Ambient Particles in Urban Aerosol in Budapest, Hungary

The absorption properties of ambient urban aerosols as well as their size distributions were measured in real-time using a dual wavelength optical particle spectrometer (DWOPS). A photoacoustic spectrometer (PAS) was simultaneously used to directly measure light absorptivity of the particles in question along with an Aethalometer and a commercial optical particle counter (OPC). The sizing perfo...
