Kim et al. (2002) studied composition of size-fractionated particulate air pollution in urban sites of Los Angeles, California, with considerable mobile source emissions.
In this study, we used the elemental composition of size-fractionated particles to identify several distinct source-related fractions of fine particles and examined the association of these fractions with daily mortality in each of the six cities.
We designed the present study to characterize the chemical composition of size-fractionated airborne PM collected at either 20 or 275 m from an interstate highway and to determine the cardiopulmonary toxicity of the particles after oropharyngeal aspiration in mice.
This study uses inductively coupled plasma mass spectrometry and ion chromatography to compare the elemental composition of size-fractionated underground PM with woodstove, roadwear generator, and road tunnel PM.
This study provided evidence that, for a similar interface composition (i.e. the MFGM), the amount of the interface directly influences the digestion of milk fat globules (see Lopez et al. 2011 for details about the preparation and composition of size-partitioned milk fat globules).
For the ease of understanding we only discussed important relationships that give us new insight into the complex composition of grain size and shape components.
Age, sex, weight, height and corporal mass have no statistically significant effect on the aerosol composition in terms of size and number of droplets.
We then discuss issues critical to successful application of EHDA technique, including control of composition, size, shape, morphology, structure of particulate materials and their assembly.
NEPs are peptides that we expect to find frequently in view of the composition and size of the sequence database for each kingdom.
The iron powder design parameters were the composition of graphite, particle size, and the composition of lubricant.
We were not able to study the chemical composition of the UFP size modes.
