Impacts of condensable particulate matter on atmospheric organic aerosols and fine particulate matter (PM _2.5 ) in China

Atmospheric Chemistry and Physics, 2022
Abstract. Condensable particulate matter (CPM) emitted from stationary combustion and mobile sources exhibits high emissions and a large proportion of organic components. However, CPM is not generally measured when conducting emission surveys of PM in most countries, including China.

Organ-on-a-Chip: Opportunities for Assessing the Toxicity of Particulate Matter [PDF]

Frontiers in Bioengineering and Biotechnology, 2020
Recent developments in epidemiology have confirmed that airborne particulates are directly associated with respiratory pathology and mortality. Although clinical studies have yielded evidence of the effects of many types of fine particulates on human health, it still does not have a complete understanding of how physiological reactions are caused nor ...

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.

Sorption of polycyclic aromatic hydrocarbons on particulate organic matters [PDF]

Journal of Hazardous Materials, 2010
Particulate organic matter (POM) is a key organic matter fraction which can influence soil fertility. Its interactions with hydrophobic organic pollutants (HOCs) have not been characterized and the mechanisms of retention of HOCs by POM remain unclear. In the present study, sorption behaviors of polycyclic aromatic hydrocarbons (PAHs) naphthalene (NAP),

Sink or link? The bacterial role in benthic carbon cycling in the Arabian Sea's oxygen minimum zone [PDF]

Biogeosciences, 2013
The bacterial loop, the consumption of dissolved organic matter (DOM) by bacteria and subsequent transfer of bacterial carbon to higher trophic levels, plays a prominent role in pelagic food webs.

Pigments, elemental composition (C, N, P, and Si), and stoichiometry of particulate matter in the naturally iron fertilized region of Kerguelen in the Southern Ocean [PDF]

Biogeosciences, 2014
The particulate matter distribution and phytoplankton community structure of the iron-fertilized Kerguelen region were investigated in early austral spring (October–November 2011) during the KEOPS2 cruise.

Seasonal dynamics of carbon and nutrients from two contrasting tropical floodplain systems in the Zambezi River basin [PDF]

Biogeosciences, 2015
Floodplains are important biogeochemical reactors during fluvial transport of carbon and nutrient species towards the oceans. In the tropics and subtropics, pronounced rainfall seasonality results in highly dynamic floodplain biogeochemistry. The massive
