Article Synopsis
- Reservoirs in river networks play a crucial role in nitrogen processing, with factors like water residence time significantly influencing nitrogen deposition and transformation.
- The study examined sediment cores from eight reservoirs in contrasting watersheds—one urbanized and regulated, the other rural and unregulated—to assess the relationship between sediment nitrogen concentrations and residence time, along with other parameters.
- Findings indicated a strong correlation between longer residence times and increased nitrogen deposition due to enhanced algal uptake, with drought conditions further extending residence times and potentially elevating sediment nitrogen levels by 2.5-4%.
Recent studies have shown that sediments of temperate and tropical lakes are sinks for organic carbon (OC), but little is known about OC burial in subtropical lakes. There are questions regarding the ability of subtropical lakes to store OC, given their relatively warmwater temperatures, lack of ice cover, frequent water-column mixing, and labile carbon forms. We used 210Pb-dated sediment cores from 11 shallow Florida (USA) lakes to estimate OC burial, i.

Metal pollution, in particular, is a reported consequence of elevated anthropogenic inputs, especially from urbanized areas. The objectives of this study were to quantify metal (Cu, Al, Cd, Ni, and Pb) concentrations in the waters and biota of four streams in South Georgia, USA, and relate metal concentrations to land use and abiotic and biotic stream processes.
