Polar organic fraction of air particulate matter
Journal of Chromatography A, 1979Abstract Air particulate matter collected on glass-fibre filters was extracted with dichloromethane and subsequently with methanol. The methanol extract was derivatized and analysed by capillary-column gas chromatography and gas chromatography-mass spectrometry. About 20 components, mostly polyols, were identified. It is speculated that these polyols

δ13C analyses of oceanic particulate organic matter
Marine Chemistry, 1973Abstract Seventy-nine δ 13 C analyses of oceanic particulate matter (> 0· μ ) from semi-tropical (Gulf of Mexico, Caribbean and Atlantic) and polar (South Indian Ocean) waters showed that the carbon isotope composition of the particulate matter from the cold polar surface waters was lighter ( −24·7 to −26·0‰ ) than that from the surface in the ...

Coarse Particulate Organic Matter in Streams
1981Coarse particulate organic matter (CPOM) has been defined as particulate organic matter >1 mm in size. Since its transport and movement in streams is the topic of another chapter in this book (Dance, Chapter 3), our discussion will mainly deal with such aspects as sources of CPOM, its processing and decomposition and importance as a food source to ...

Analysis of Organic Particulate Matter
1995The organic fraction of airborne particulate matter contains hundreds or even up to thousands of chemical components of natural and anthropogenic origin. Many of them have received considerable attention in recent years due to their adverse health effects.

Mechanical Grinding for Particulate Organic‐Matter Analysis
Communications in Soil Science and Plant Analysis, 2008Abstract Particulate organic matter (POM) is recognized as a valuable measure of labile soil organic matter. The method usually requires hand‐sieving through a 2‐mm sieve. Hand‐sieving has not been widely adopted by soil testing laboratories, where samples are generally mechanically ground. Composites of 20–25 cores (2×15 cm) were collected from a long‐

Photodissolution of particulate organic matter from sediments
Limnology and Oceanography, 2006Irradiation of particulate organic matter (POM) at light intensities found at the earth's surface should induce reduction in molecular weight, as found for dissolved organic matter, and hence result in transfer to the dissolved phase. We studied Mississippi River suspended sediments to test if photodissolution can induce losses of POM similar to those ...

Carbon of Particulate Organic Matter
1984At present the particulate material, one of the components of which in natural waters is OM, is assumed to comprise that part of OM which is retained in the filters with 0.45 – 1 µm pore size or in separators. Large OM particles in natural waters are present in an extremely scattered state and are usually not to be found in filtration particulate ...

Interactions with Ligands, Particulate Matter and Organisms
1984A rough description of the occurrence and behaviour of trace metals in aquatic and terrestrial systems is presented in Fig. 5. In the aquatic environment four abiotic reservoirs are distinguished: the suspended matter, the sediments, the surface waters and the pore waters. These four reservoirs strongly interact with each other.
