Ubiquity of organic nitrates from nighttime chemistry in the European submicron aerosol
Geophysical Research Letters, 2016 In the atmosphere nighttime removal of volatile organic compounds is initiated to a large extent by reaction with the nitrate radical (NO3) forming organic nitrates which partition between gas and particulate phase.

Particulate organic matter in artificial soils
, 2019 It is estimated that around 2 109 hectares of land (15% of global land area) has been degraded by human activity, and rates of soil degradation are increasing. Soil is a precious resource, it sustains almost all terrestrial life and provides 90% of the food that feeds humanity.

Can neap-spring tidal cycles modulate biogeochemical fluxes in the abyssal near-seafloor water column? [PDF]
, 2017 Before particulate matter that settles as ‘primary flux’ from the interior ocean is deposited into deep-sea sediments it has to traverse the benthic boundary layer (BBL) that is likely to cover almost all parts of the seafloor in the deep seas.

Use of Stable Nitrogen Isotope Signatures of Anthropogenic Organic Matter in the Coastal Environment: The Case Study of the Kosirina Bay (Murter Island, Croatia) [PDF]
, 2011 In this study stable nitrogen isotope ratios of particulate matter POM, zooplankton and selected biota such as Mytilus galloprovincialis were used to assess the impact of anthropogenically derived organic matter from the untreated domestic sewage ...

Aquatic Insect Colonization and Substrate Changes in a Relocated Stream Segment [PDF]
, 2017 A section of Bear Creek in northwestern Wisconsin was relocated to accommodate new highway construction. The 850-m section of the stream was shortened to 650 m and fashioned with five broad bends and a uniform width and depth. Sandy substrate and lack of

Dual stable isotope abundances unravel trophic position of estuarine nematodes [PDF]
, 2005 The role and quantitative importance of free-living nematodes in marine and estuarine soft sediments remain enigmatic for lack of empirical evidence on the feeding habits and trophic position of most nematode species.

Two-stroke scooters are a dominant source of air pollution in many cities. [PDF]
, 2014 Fossil fuel-powered vehicles emit significant particulate matter, for example, black carbon and primary organic aerosol, and produce secondary organic aerosol. Here we quantify secondary organic aerosol production from two-stroke scooters.

Characteristics of heavy metals and their evaluation in suspended sediments from Piracicaba river basin (São Paulo, Brazil) [PDF]
, 2010 Fluxes of the particulate heavy metals like chromium (Cr), copper (Cu), cobalt (Co), nickel (Ni), zinc (Zn) and lead (Pb) were determined along the Piracicaba River basin.
