Unveiling the new round of trade-in policies in China: an “objectives-tools-targets” analysis framework

Trade-in policies play an important role in advancing sustainable consumption in China, but their sustained effectiveness still faces obstacles. This study constructs a trade-in policy mix analysis framework, which integrates the three dimensions of policy objectives, tools and t...

Spontaneous ChlorineGeneration via Interfacial Oxidationof Chloride by O2 on Acidic Microdroplets

Abstract Reactive chlorine species significantly influence atmospheric chemistry, yet their sources remain inadequately defined. We have discovered a spontaneous formation pathway for substantial molecular chlorine (Cl2) from the oxidation of chloride (Cl–) through interfacial ox...

From raw to cooked: The impact of cooking on bioaccessibility and health risks of toxic elements in leafy vegetables

Environmental policies in China have significantly reduced toxic element fluxes in soil and air, but slower declines in atmospheric toxic element flux have increased its relative contribution to crop contamination. Leafy vegetables, with their large surface area and high capacity...

Multi-Level Characteristics of Consumption-Driven Virtual Water Flows: Sustainability Insights from the Pearl River Delta Urban Agglomeration

Urban agglomerations rely on both direct physical water intake and substantial virtual water embedded in cross-regional traded commodities and services to meet water demand. It is important to analyze the complex virtual water flows in urban agglomerations to advance sustainable...

Spatial-Economic Assessment of Biomass Supply Chains Under Land Fragmentation

Taking Lankao County as a case study, this study extends the established StrawFeed framework by linking NHPI-derived harvest dates to spatially differentiated straw release and seasonal equipment scheduling. Time-series Sentinel-2 observations were used to characterize harvest ti...

Dual-Spatial-Scale Assessment of Watershed Water Yield Responses to Land-Use Change in the Upper Yangtze River Basin

Understanding how land change affects water yield is essential for sustainable land management and water security. However, previous studies often rely on a single model or spatial scale, limiting their ability to capture fine-scale land-surface heterogeneity and basin-integrated...
