Coarse Particulate Organic Matter Budgets

Methods to Study Litter Decomposition, 2020
An organic matter budget is a systematic account of organic matter inputs and outputs in an ecosystem or parts thereof. To construct a coarse particulate organic matter (CPOM) budget for a stream, CPOM inputs, outputs and storage can be measured according to methods described in other chapters of this book.

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 ...

Nano-plastics induce aquatic particulate organic matter (microgels) formation.

Science of The Total Environment, 2019
The pervasive presence of plastic waste in the aquatic environment is widely viewed as one of the most serious environmental challenges for current and future generations. Microplastics ultimately degrade into nano and smaller-sizes.

Photochemical production of singlet oxygen from particulate organic matter.

Environmental Science & Technology, 2015
Dissolved organic matter is established as one of the most relevant photosensitizers in aquatic environments, producing singlet oxygen (1O2) alongside other photochemically produced reactive intermediates. While the production of 1O2 from DOM has been well studied, the relative importance of particulate organic matter (POM) to the overall 1O2 ...

Photogeochemistry of particulate organic matter in aquatic systems: A review.

Science of the Total Environment, 2021
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.

Climate, carbon content, and soil texture control the independent formation and persistence of particulate and mineral-associated organic matter in soil

, 2020
Understanding the mechanisms controlling the formation and persistence of soil organic matter (SOM) is important for managing soil health and sustainable food production. The formation of SOM and the degree to which it is protected from decomposition are
