Risk assessment of heavy metals in suspended particulate matter in a typical urban river

Wenye Li et al.

Summary: This study examines the spatial distribution, potential ecological risks, and sources of heavy metals associated with suspended particulate matter (SPM) in the Beiyun River in northern China. The results reveal a high potential ecological risk in the study area, with cadmium representing the highest pollution risk among the measured heavy metals.

Long-term surface water mapping in the Pearl River Delta based on multiple satellite images

Mengmeng Hu et al.

Summary: This study evaluates the changes in surface water dynamics in the Pearl River Delta (PRD) over a 30-year period of high-intensity economic development. It found that while the total surface water area has increased, the landscape pattern has become more fragmented and complex, with a significant growth in fish ponds. These findings underscore the importance of patterns, structures, and policies in surface water dynamic analyses.

The land-to-ocean loops of the global carbon cycle

Pierre Regnier et al.

Summary: This study assesses the land-to-ocean cycling of carbon through inland waters, estuaries, tidal wetlands and continental shelf waters, and highlights the impact of neglecting these changing carbon fluxes on carbon storage estimates. Key knowledge gaps are identified for future assessments to reduce uncertainties in understanding the global carbon cycle.

Isotopic constraints confirm the significant role of microbial nitrogen oxides emissions from the land and ocean environment

Wei Song et al.

Summary: Nitrogen oxide (NOx) emissions and deposition have significantly increased in terrestrial and oceanic environments, with microbial NOx emissions being underestimated on land and unconstrained in the ocean. This study provides empirical constraints on global NOx emissions, demonstrating the significant contribution of microbial nitrogen cycles to regional NOx emissions.

Coastal currents regulate the distribution of the particulate organic matter in western Guangdong offshore waters as evidenced by carbon and nitrogen isotopes

Fajin Chen et al.

Summary: The study found that the POM in western Guangdong waters is significantly influenced by coastal currents in spring and summer, with a higher proportion of terrestrial organic matter in spring and a lower proportion in summer, mainly due to inadequate nutrients brought by the coastal currents.

Multiple isotopic compositions reveal complex nitrogen cycling in a subtropical estuary

Hao Jiang et al.

Summary: Nitrogen (N) pollution and eutrophication can harm estuarine ecosystems, with understanding N sources and cycling crucial for management. In the Pearl River Estuary (PRE), a multiple-isotopic approach revealed contrasting N dynamics between the west and east, with NO3- largely influenced by mixing in the west and assimilation/nitrification in the east. River discharge and nitrification were major contributors to the NO3- pool, while NH4+ mainly originated from river discharge.

Quantifying influences of anthropogenic-natural factors on ecological land evolution in mega-urban agglomeration: A case study of Guangdong-Hong Kong-Macao greater Bay area

Rundong Feng et al.

Summary: The study found that ecological land shifted from decline and fragmentation to growth and integration over the period from 1990 to 2019. Population density and land urbanization rate were identified as the main controlling factors for ecological land evolution, with interactions between driving factors being bivariate. Anthropogenic factors had a greater influence on ecological land than natural factors, with the impact of population density and GDP per capita steadily increasing. Additionally, the effect of average annual temperature and precipitation declined due to the intensification of anthropogenic activities.

Effects of land use and land cover on soil erosion control in southern China: Implications from a systematic quantitative review

Jia Chen et al.

Summary: The study found that bare land has the greatest impact on soil erosion, while cropland and grassland have the smallest impact. When vegetation coverage exceeds 60%, soil erosion tends to stabilize. Land use with multiple vegetation layers or contact cover can reduce runoff and sediment values.

Sources, transformations of suspended particulate organic matter and their linkage with landscape patterns in the urbanized Beiyun river Watershed of Beijing, China

Jin Liu et al.

Summary: This study investigated the sources and transformations of suspended particulate organic matter (POM) within the Beiyun River Watershed, as well as the influence of landscape patterns on POM, using stable carbon and nitrogen isotope techniques combined with multiple statistical analyses. The study found significant spatial fluctuations in POM variables under different urban development gradients, with different POM sources existing in the rainy season and dry season. The study also highlighted the importance of landscape metrics in correlating with POM variables over seasons, providing insights for urban river water quality improvement strategies.

Sources and transformation mechanisms of inorganic nitrogen: Evidence from multi-isotopes in a rural-urban river area

Huijun Ye et al.

Summary: The application of multi-isotope tracers quantitatively revealed the sources and transformation mechanisms of inorganic nitrogen in a complex land use area in China, showing seasonal and spatial differences in contributions and transformation mechanisms. While nitrate nitrogen in rural areas mainly came from nitrogen fertilizer application and soil nitrogen, urban areas were influenced by soil nitrogen, manure and sewage, and industrial wastewater, with different contributions in varying seasons and locations.

Characterization of sedimentary organic matter and depositional processes in the Mandovi estuary, western India: An integrated lipid biomarker, sedimentological and stable isotope approach

Mehta Bulbul et al.

Summary: A multiproxy study was conducted on surface sediments from the Mandovi estuary in Goa, India, revealing higher terrigenous organic matter accumulation in the upper reaches and intense human activity in the lower estuary with petroleum contamination. Grain size was found to play a significant role in the distribution of organic matter along coastal margins.

Carbon and nitrogen isotopic compositions of particulate organic matter in the upwelling zone off the east coast of Hainan Island, China

Xuan Lu et al.

Summary: The study revealed that during summer, suspended particulate organic matter (POM) off the east coast of Hainan Island in the South China Sea is influenced by coastal upwelling, coastal current, and freshwater discharge. Stable isotope analysis can reflect the sources of POM and their cycling in the marine ecosystem.
