Sampling and Analysis of Organic Compounds in Diesel Particulate Matter

Environmental Monitoring and Assessment, 2000
The fraction of atmospheric semi-volatile organic compounds (SVOC) is partitioned between the gaseous and particulate phases. Certain of these compounds eg. polynuclear aromatic hydrocarbons (PAH) and their derivatives have been shown to exhibit mutagenic or carcinogenic properties.

Analysis of Organic Particulate Matter

1995
The 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.

Particulate Organic Matter along the Northern Sea Route

Океанология, 2015
The comparative evaluation of the content of particulate organic carbon (POC) in surface seawater along the Northern Sea Route from Norway to the East Siberian Sea (the southern track) during the summer seasons of 2004–2011 was carried out based on the authors’ data. The content and distribution of organic component in particulate matter were estimated,

Decomposition of Fine Particulate Organic Matter

2020
Fine particulate organic matter (FPOM) ranges in size from 0.45 μm to 1 mm. It serves as an important food source for aquatic fauna, as a substrate for heterotrophic microorganisms, and as a carrier of nutrients, metals and other chemicals. In streams, FPOM is derived from leaf litter, algae and other organisms by physical, chemical, and biological ...

Sorption of organic genotoxins to particulate matter in industrial effluents

Environmental and Molecular Mutagenesis, 1996
In an earlier work [White PA et al. (1996): Environ Mol Mutagen 27:116-139] we examined the genotoxicity of dichloromethane extracts from a variety of industrial effluent samples. in this companion work, we used the SOS Chromotest to investigate the sorption of the extracted genotoxins to effluent suspended particulate matter.

Carbon of Particulate Organic Matter

1984
At 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 ...

Interaction of Dissolved Organic Matter with Particulate Plastics

2020
The United Nations Environment Programme has identified land-based sources of Particulate plastics (PPs), which make up the majority of them found within the marine environments. PP fragments in the terrestrial and aquatic environments have been known to host a plethora of microorganisms.

Polar organic fraction of air particulate matter

Journal of Chromatography A, 1979
Abstract 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

Coarse Particulate Organic Matter in Streams

1981
Coarse 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 ...

The Role of Particulate Organic Matter in Phosphorus Cycling

Soil Science Society of America Journal, 2003
In tropical cropping systems, a better understanding of P transformations and short‐term P cycling during decomposition of incorporated residues is pertinent. The primary objectives of this study were (i) to assess P immobilization in decomposing residues of sorghum ( Sorghum bicolor (L ...
