On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1478-1491, August 2026.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.

Pollen Mineralization Fuels Biogeochemical Cycling and Microbial Community Succession in Lake Superior

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract Pollen is a terrigenous particulate regarded as recalcitrant organic matter (OM) in aquatic ecosystems, seasonally introducing undetermined quantities of terrigenous OM to inland lakes. The role of pollen as a carbon and nutrient delivery mechanism for large aquatic ecosystems remains an understudied component of biogeochemical cycling.

Closely related phytoplankton species produce similar suites of dissolved organic matter

Frontiers in Microbiology, 2014
Production of dissolved organic matter (DOM) by marine phytoplankton supplies the majority of organic substrate consumed by heterotrophic bacterioplankton in the sea.

Dissolved organic matter (DOM) release by phytoplankton in the contemporary and future ocean [PDF]

European Journal of Phycology, 2014
The partitioning of organic matter (OM) between dissolved and particulate phases is an important factor in determining the fate of organic carbon in the ocean. Dissolved organic matter (DOM) release by phytoplankton is a ubiquitous process, resulting in 2–50% of the carbon fixed by photosynthesis leaving the cell.

Flushing of Subsurface Soil Nitrate as the Primary Cause of Increased Stream Nitrate During Storm Events

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract The export flux of nitrate from forested catchments via streams typically increases during storms due to simultaneous increases in the nitrate concentration and flow rate. Potential nitrate sources responsible for this increase include rainwater and soil nitrate.

Long‐Term Change in the Concentration‐Discharge Relationship Suggests Controls on Watershed Exports of Dissolved Organic Carbon From Forested Headwater Streams

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract Dissolved organic carbon (DOC) export from watersheds by streams is an important and changing component of the global carbon cycle. We examined controls on DOC export by quantifying changes in the DOC concentration‐discharge relationship between 1992 and 2022 for nine forested headwater catchments at the Hubbard Brook Experimental Forest ...

Savanna soil carbon accrual occurs through particulate organic matter from grass rather than tree biomass, regardless of atmospheric CO2 levels

Functional Ecology, Volume 40, Issue 8, Page 2532-2547, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Afforestation schemes in savannas are increasingly promoted as a carbon storage strategy despite threats to biodiversity. We also lack a clear understanding of how trees and grasses differentially contribute to the major carbon store in savannas, that is, soil organic ...

Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Dose–Response Effect of Glucagon on Glucose, Beta‐Cell Secretion and Metabolism in Healthy Individuals

Diabetes, Obesity and Metabolism, Volume 28, Issue 8, Page 6941-6949, August 2026.
ABSTRACT Aim Glucagon is a key regulator of glucose and energy metabolism, yet the dose–response effects of glucagon on markers of metabolism in humans are not fully characterised. We investigated the dose‐dependent effects of glucagon on glucose metabolism, β‐cell secretion and markers of hepatic metabolism in healthy adults.
