Particulate matter

2013
The physical and chemical characteristics of atmospheric particulate matter (PM) are discussed stepwise by presenting size representations in computer models, size and chemical profiles of various PM sources, mixing states of PM in ambient air, and observed ambient PM compositions in sequence. Photochemical mechanisms of formation for secondary organic

Particulate Matter Formation

2015
This chapter deals with the causes and consequences of exposure from emissions of primary particles and secondary particle precursors on human health and how to deal with them in life cycle impact assessment (LCIA).

Carbonaceous Particulate Matter

2014
Ambient particulate matter affects local/regional air quality, human health and climate change significantly. The carbonaceous fractions like organic carbon (OC) and elemental carbon (EC, sometimes known as black carbon) are of high interest for scientists all over the world.

Particulate Matter of Particular Interest

Annals of Internal Medicine, 1973
Excerpt Few physicians are aware that during the intravenous administration of certain medications, notably antibiotics, fibers of asbestos may also be infusing into their patients.

Particulate Matter in Urban Air

2003
Research within SATURN has focussed on improving our understanding of the physical and chemical properties of particulate matter, and our capability for modelling particulate matter concentrations in urban areas. Campaigns have been conducted at various urban centres on PM10, PM2.5 and on finer size fractionated samples.

Decomposition: Particulate Organic Matter

1991
Decomposition completes the biogeochemical cycles that photosynthesis initiates. Thus, complete decomposition results in the conversion of the organic (reduced) products of photosynthesis back into the inorganic (generally oxidized) constituents used as the reactants for photosynthesis (see Exercise 14).

Multipolar effects in particulate matter

Solid State Communications, 1984
Abstract The effect of induced multipoles on the surface modes of particulate matter in the quasistatic regime are discussed. Numerical evidence suggests that the dipole approximation fails for an interparticle distance σ of 1.5 particle diameters.

Particulate Matter Composites

1992
The response of particulate matter to shock treatment has been under investigation for several decades, but usually in connection with metallic powder compaction. It is only in the last 20 years or so that the interest in the changes effected by the passage of a shock wave through nonmetallic powder materials ceased to be purely academic.
