Quantifying Black Carbon Mixing State Heterogeneity Using a Machine Learning Model

Junchang Wang, Wenxiang Shen, Minghuai Wang, Zhonghua Zheng et autres

Abstract The climate impact of black carbon (BC) is strongly sensitive to the mass ratio of non‐BC coatings to BC (R BC ). However, current global climate models (GCMs) typically assume a uniform composition within individual BC‐containing particle populations, neglecting the significant …

Improved representation of isoprene-derived secondary organic aerosol in CAM6-Chem reveals regional contrasts in its long-term changes over China

Wei Zhang, Man Yue, Xinyue Shao, Xinyi Dong et autres

Abstract. Isoprene-derived secondary organic aerosol (ISOA) is an important component of atmospheric organic aerosol, but its formation remains incompletely represented in global chemical models, creating uncertainty in ISOA changes and their drivers. In this study, we updated the explicit isoprene chemistry scheme …

A modeling study of global distribution and formation pathways of highly oxygenated organic molecules (HOMs) from monoterpenes

Xinyue Shao, Yaman Liu, Xinyi Dong, Minghuai Wang et autres

Abstract. Highly oxygenated organic molecules (HOMs) derived from monoterpenes are key precursors of secondary organic aerosols (SOA), yet their global-scale formation pathways and climate impacts remain poorly quantified due to uncertainties in autoxidation kinetics and branching ratios of peroxy radicals. Here, we …

The effect of organic nucleation on the indirect radiative forcing with a semi-explicit chemical mechanism for highly oxygenated organic molecules (HOMs)

Xinyue Shao, Minghuai Wang, Xinyi Dong, Yaman Liu et autres

Highly oxygenated organic molecules (HOMs) can significantly contribute to new particle formation (NPF). HOM-derived NPF in preindustrial (PI) environments provides the baseline for calculating radiative forcing, yet global model studies examining this are lacking. Here, we use a global climate model with …

Simultaneous Determination and Dietary Risk Assessment of 26 Pesticide Residues in Wheat Grain and Bran Using QuEChERS-UHPLC-MS/MS

Hongwei Zhang, Xinyi Dong, Xueyang Qiao, Chunyong Li et autres

Evaluating the potential chronic health risks posed by pesticides to consumers is essential for ensuring food safety and protecting public health. An ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS) method coupled with modified QuEChERS extraction was developed to simultaneously determine 26 pesticide residues …

Effect of digestion system on microstructures of microplastics from biodegradable polyesters and impact of these microplastics on microorganisms in digestion system

Z. Wu, Yanan Li, Hongmei Chen, Xinyi Dong et autres

The environmental impact from microplastics (MPs) has garnered increasing attention. All the biodegradable polymers developed for reducing plastics pollution will also generate bio-MPs. This study firstly explores systematically the bio-MPs from two key aspects: first, the effects of digestive system on these …

Evaluation of Modeled Carbon Monoxide and Methane Columns in the High Arctic Using TCCON Measurements

Erin McGee, Kimberly Strong, Kaley A. Walker, Cynthia Whaley et autres

Abstract Methane (CH 4 ) and carbon monoxide (CO) are gases with important climate impacts as direct and indirect greenhouse gases, respectively. Methane has a warming potential 28 times that of carbon dioxide on a 100‐year timescale, and carbon monoxide is a …
