Variation of size-segregated particle number concentrations in wintertime Beijing

Size-Segregated Particle Number Concentrations and Respiratory Emergency Room Visits in Beijing, China

BACKGROUND The link between concentrations of particulate matter (PM) and respiratory morbidity has been investigated in numerous studies. OBJECTIVES The aim of this study was to analyze the role of different particle size fractions with respect to respiratory health in Beijing, China. METHODS Data on particle size distributions from 3 nm to 1 µm; PM10 (PM ≤ 10 µm), nitrogen dioxide (NO(2))...

A method for generating uniform size-segregated pyrite particle fractions

BACKGROUND Standardized sample preparation techniques allow comparison of pyrite dissolution experiments under diverse conditions. Our objective was to assess dry and wet sieving preparation methodologies, and to develop a reproducible technique that yields uniformly size-distributed material within a limited size range of interest. RESULTS Here, we describe a wet sieving preparation method t...
