Ecophysiology of uncultivated marine euryarchaea is linked to particulate organic matter

The ISME Journal, 2015
Particles in aquatic environments host distinct communities of microbes, yet the evolution of particle-specialized taxa and the extent to which specialized microbial metabolism is associated with particles is largely unexplored.

Root‐zone enrichment of particulate and nonparticulate organic carbon and nitrogen under grassland management and woodlands across a soil texture gradient in North Carolina, USA

Grassland Research
Background Surface‐soil organic matter accumulation is expected under well‐managed grasslands. Characterizing particulate and nonparticulate organic C and N fractions across a soil texture gradient under different conservation land management systems ...

Study of the trace metal ion influence on the turnover of soil organic matter in cultivated contaminated soils [PDF]

, 2006
The role of metals in the behaviour of soil organic matter (SOM) is not well documented. Therefore, we investigated the influence of metals (Pb, Zn, Cu and Cd) on the dynamic of SOM in contaminated soils where maize (C4 plant) replaced C3 cultures. Three

Unveiling the mechanism secret of abrasion emissions of particulate matter and microplastics

Scientific Reports
Recent research highlights that non-exhaust emissions from the abrasion of tires and other organic materials have emerged as a substantial source of airborne particulate matter and marine microplastics.

Chemical composition modulates the adverse effects of particles on the mucociliary epithelium

Clinics, 2015
OBJECTIVE:We compared the adverse effects of two types of real ambient particles; i.e., total suspended particles from an electrostatic precipitator of a steel mill and fine air particles from an urban ambient particulate matter of 2.5 µm, on mucociliary

Organic carbon flux and particulate organic matter composition in Arctic valley glaciers: examples from the Bayelva River and adjacent Kongsfjorden

, 2016
. In the face of ongoing global warming and glacier retreat, the composition and flux of organic matter in glacier–fjord systems are key variables for updating the carbon cycle and budget, whereas the role of Arctic valley glaciers seems unimportant when

Kaji Eksperimental Pengaruh Pembebanan terhadap Emisi Debu Partikulat pada Motor Bensin

Jurnal Rekayasa Kimia & Lingkungan, 2011
The effect of engine loading on emission of particulate matter was studied by using an Otto engine (Honda astrea grand 110 cc). In the experiment, the characteristics of loading engine, fuel consumption and composition of particulate matter were ...

Distribution of inorganic and organic nutrients in the South Pacific Ocean – evidence for long-term accumulation of organic matter in nitrogen-depleted waters [PDF]

, 2007
International audienceThe BIOSOPE cruise of the RV Atalante was devoted to study the biogeochemical properties in the South Pacific between the Marquesas Islands (141° W–8° S) and the Chilean upwelling (73° W–34° S).

Ships, ports and particulate air pollution - an analysis of recent studies [PDF]

, 2011
The duration of use is usually significantly longer for marine vessels than for roadside vehicles. Therefore, these vessels are often powered by relatively old engines which may propagate air pollution.

Partition of copper between dissolved and particulate phases using aluminum oxide as an aquatic model phase: effects of pH, solids and organic matter

Journal of the Brazilian Chemical Society, 2000
The sorption of copper ions from aqueous solutions onto modified aluminum oxide was investigated as a function of pH, solids concentration and both particulate and dissolved organic matter.
