TL;DR: A default use of the prevalent lognormal distribution model can lead to significant misestimates of PSD parameters such as mean diameter, median diameter, and variance, as well as the gamma and Weibull distribution models, which may be considered as alternative options.

TL;DR: In this article, PM10 and PM2.5 samples were collected from twelve swine (farrowing, gestation, weaning, and finishing) and six poultry (layer hen and tom turkey) confinement buildings in the U.S. Midwest and their inorganic composition, in terms of trace elements and ions, was investigated.

TL;DR: The concentration, size, and density of TSP samples varied greatly with animal species, housing facility type, feeder type, and season, suggesting that PM emission data derived from limited measurements may not be readily applied to estimate the overall emission from concentrated animal feeding operations (CAFOs).

TL;DR: Particles from different types of CAFOs shared a more similar odorant composition, contained higher odorant concentrations per mass of particles, and accounted for on average 53.2% of the odor strength of their corresponding TSP samples.

TL;DR: In this article, a cylindrical convective chamber was developed to monitor gas emissions from dusts, and a low-temperature thermal desorption technique was applied to extract ammonia and odorous gases adsorbed by the dust in the chamber.
