Transformation processes of total suspended solids and dissolved organic matter in rivers: Influences of different land use sources and degradation processes.

The riverine dissolved organic matter (DOM) pool constitutes the largest and most dynamic organic carbon reservoir within inland aquatic systems. Human activities significantly alter the distribution of organic matter (OM) in rivers, thereby affecting the availability of DOM. However, the impact of total suspended solids (TSS) on DOM under anthropogenic influence remains insufficiently elucidated.

Peatlands are significant global carbon sinks; however, their carbon storage functions are vulnerable to human activities. In the Greater Khingan Mountains of Northeast China, where forest and peatland ecosystems are interspersed extensively, prescribed burning is conducted annually on peatlands to prevent major forest fires. To investigate the effect of prescribed burning on carbon and nutrient cycling processes in peatlands, we conducted a three-year experiment in the Greater Khingan Mountains.

Since the Industrial Revolution, significant changes in global land-use patterns have occurred, which have disrupted terrestrial carbon emissions. However, the disturbance processes, change trends, and distribution patterns are not clear. Therefore, the changes in terrestrial carbon emissions (E) caused by land-use change (LUC) since 1850 were analyzed in this study.

This study examines the seasonal variations in carbonate system parameters in the East China Sea (ECS) off the Yangtze River estuary (YRE) and analyzes the contributions of anthropogenic CO₂ and eutrophication to acidification. Carbonate parameters data were collected during summer 2019 and combined winter 2011. During winter, acidification is primarily driven by rising atmospheric CO₂, with minimal impact from biological processes.

Environmental taxes play a critical role in mitigating air pollution and fostering sustainability by internalizing the social costs of environmental damage. By imposing financial disincentives on polluters, these taxes encourage cleaner practices and technological innovation. Using panel ARDL models, this study examines the impact of environmental taxes on CO₂ emissions across 38 OECD countries, accounting for cross-sectional dependence, non-stationarity, and heterogeneity.
