An integrated approach for multi-species VOC impact assessment from multiple organized point sources in industrial parks using dynamic dispersion modeling

Volatile organic compound (VOC) impacts in chemical industrial parks are shaped by dynamic emissions, diverse source configurations, and meteorological variability, complicating source attribution and exposure assessment. Existing methods often lack source specificity, overlook e...

Profile-wide desalinization is associated with increased deep-soil microbial biomass and reduced iron-bound carbon in coastal wetland restoration

Tillage- and mulching-based interventions are increasingly used to control invasive plants and modify soil hydro-salinity, but their effects on subsoil carbon (C) stabilization are poorly quantified. We conducted an 18-month field experiment in a Spartina alterniflora–invaded est...

Spatiotemporal Characteristics of Carbon Source–Sink Dynamics in the Coastal Waters of the South Yellow Sea, China

Continental-shelf marginal seas play a pivotal role in the global carbon cycle. The coastal South Yellow Sea (SYS), located in an intense land–ocean interaction zone, is a key region for coastal carbon cycle research. The issue addressed in this region is that strong land–sea int...

Flocculation and Dewatering Mechanisms of Pyrite Flotation Tailings: Synergistic Roles of Polyferric Chloride, Polydiallyldimethylammonium Chloride, and Skeleton Builders on Microstructure Evolution

This study investigates the conditioning and deep dewatering of pyrite tailings slurry using a composite system comprising polyferric chloride (PFC), polydiallyldimethylammonium chloride (PDMDAAC), and fly ash as a skeleton builder. The synergistic application significantly enhan...
