Novel Insights into Driving Forces of Carbon Burial, Nutrient Heterogeneity, and Pollutant Release Pathways in Urban Lake Sediments

Key Points

• Carbon burial rates varied across sediment layers, indicating significant nutrient heterogeneity and sediment dynamics.
• High pollutant release was associated with specific sediments, showcasing the connection between urban activity and sediment quality.
• Observational analysis across several urban lakes demonstrated variability in carbon burial and pollutant pathways, underscoring ecological consequences.
• Identifying how urban sediments affect carbon and nutrient dynamics may aid in environmental management and pollution mitigation.
