An 11,000-year record of depositional environmental change based upon particulate organic matter and stable isotopes (C and N) in a lake sediment in southeastern Brazil [PDF]
, 2018 The aim of this paper is to reconstruct an 11,000-year history of depositional environmental change in southeastern Brazil, based upon the integration of particulate organic matter and stable isotope (C and N) data from a 136-cm sediment core from Lake ...

Effect of Organic Particulate Matter on Vegetable Crops and their Control Potentials
E3S Web of Conferences, 2018 Air pollution has an impact, include impact to the plants. The adverse effects of air pollution have been associated with three major sources. They are gaseous pollutant and particulates from fossil fuels, manufacturing plants and vehicles.

What can we learn from amino acids about oceanic organic matter cycling and degradation? [PDF]
Biogeosciences, 2022 Amino acids (AAs) mainly bound in proteins are major constituents of living biomass and non-living organic material in the oceanic particulate and dissolved organic matter pool. Uptake and cycling by heterotrophic organisms lead to characteristic changes

Particulate Organic Matter in the Sea: The Composition Conundrum [PDF]
AMBIO: A Journal of the Human Environment, 2004 As organic matter produced in the euphotic zone of the ocean sinks through the mesopelagic zone, its composition changes from one that is easily characterized by standard chromatographic techniques to one that is not. The material not identified at the molecular level is called "uncharacterized".

A Pilot Indoor-Outdoor Study of Organic Particulate Matter and Particulate Mutagenicity [PDF]
Journal of the Air Pollution Control Association, 1985 Elevated indoor concentrations of a number of gaseous and particulate pollutants have been demonstrated by numerous workers. The case of indoor to outdoor (I/O) relationships for particulate organic matter, however, is especially complex in view of the range of organic compounds in this fraction and the need for relatively sensitive analytical ...

River Organic Carbon Fluxes Modulated by Hydrodynamic Sorting of Particulate Organic Matter [PDF]
Geophysical Research Letters, 2022 AbstractRivers regulate the global carbon cycle by transferring particulate organic carbon (POC) from terrestrial landscapes to marine sedimentary basins, but the processes controlling the amount and composition of fluvially exported POC are poorly understood. We propose that hydrodynamic sorting processes modify POC fluxes during fluvial transit.

Chemical Coupling Between Atmospheric Ozone and Particulate Matter [PDF]
, 1997 A major fraction of ambient particulate matter arises from atmospheric gas-to-particle conversion. Attempts to reduce particulate matter levels require control of the same organic and nitrogen oxide (NO_x) emissions that are precursors to urban and ...

Input of particulate heavy metals from rivers and associated sedimentary deposits on the Gulf of Lion continental shelf [PDF]
, 2008 Fluxes of the heavy metals chromium (Cr), cobalt (Co), nickel (Ni), copper (Cu), lead (Pb), cadmium (Cd) and zinc (Zn) delivered by rivers to the Gulf of Lion (NW Mediterranean Sea) were estimated over a three year study of the River Rhone and its ...

Microbial carbon recycling: an underestimated process controlling soil carbon dynamics – Part 2: A C3-C4 vegetation change field labelling experiment [PDF]
Biogeosciences, 2015 The mean residence times (MRT) of different compound classes of soil organic matter (SOM) do not match their inherent recalcitrance to decomposition. One reason for this is the stabilization within the soil matrix, but recycling, i.e.
