Photogeochemistry of particulate organic matter in aquatic systems: A review

Science of the Total Environment, 2022
Photochemical transformation of natural organic matter in aquatic environments strongly impacts the environmental behaviors of carbon, nutrients, and pollutants by affecting their solubility, toxicity, bioavailability, and mobility. However, the role of particulate organic matter (POM) in environmental photogeochemistry has received much less attention

The organic constituents of atmospheric particulate matter

Atmospheric Environment (1967), 1976
Abstract The ether soluble fraction of atmospheric aerosol particles was separated into the following groups of compounds: organic acids and phenols, organic bases, aliphatic hydrocarbons, aromatic hydrocarbons and neutral compounds. These groups in turn were analyzed for individual constituents.

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).

Interactions with Ligands, Particulate Matter and Organisms

1984
A 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.

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.
