Particulate Mercury and Particulate Organic Matter in the Itenez Basin (Bolivia)

Applied Sciences, 2020
In rivers and other freshwater bodies, the presence of mercury can be due to direct contamination by anthropic activities such as gold mining. However, it can also be attributed to atmospheric deposition and erosion, runoff, or lixiviation from ...

Soil organic carbon thresholds control fertilizer effects on carbon accrual in croplands worldwide

Nature Communications
Initiatives to restore soil fertility and mitigate global warming rely on rebuilding soil organic carbon (SOC). Nitrogen (N) fertilization is crucial for crop yields but affects SOC unpredictably due to varying responses of particulate organic carbon ...

Aged riverine particulate organic carbon in four UK catchments [PDF]

Science of The Total Environment, 2015
The riverine transport of particulate organic matter (POM) is a significant flux in the carbon cycle, and affects macronutrients and contaminants. We used radiocarbon to characterise POM at 9 riverine sites of four UK catchments (Avon, Conwy, Dee, Ribble) over a one-year period.
