Elucidating transport dynamics and regional division of PM and O in China using an advanced network model.

Air pollution exhibits significant spatial spillover effects, complicating and challenging regional governance models. This study innovatively applied and optimized a statistics-based complex network method in atmospheric environmental field. The methodology was enhanced through improvements in edge weighting and threshold calculations, leading to the development of an advanced pollutant transport network model.

Research on regional ozone prevention and control strategies in eastern China based on pollutant transport network and FNR.

O pollution in China has worsened sharply in recent years, and O formation sensitivity (OFS) in many regions have gradually changed, with eastern China as the most typical region. This study constructed the transport networks of O and NO in different seasons from 2017 to 2020. The transport trends and the clustering formation patterns were summarized by analyzing the topological characteristics of the transport networks, and the patterns of OFS changes were diagnosed by analyzing the satellite remote sensing data.

Spatial clustering and spillover pathways analysis of O, NO, and CO in eastern China during 2017-2021.

The eastern China presented the most serious O pollution and increasingly prominent regional characteristics. To understand the transport characteristics of O and its precursors and identify their potential relationships are of great guiding significance for interregional joint prevention and control. In this study, the annual and seasonal transport networks of O and its precursors (NO and CO) during 2017-2021 were constructed by applying the complex network method to air quality observations.

Influence of High Sulfate Mine Water on Spontaneous Combustion of Coal.

Mine water cannot be discharged until it has been treated, which increases the cost of mining and causes environmental damage. This paper attempted to use sulfate mine water as a flame retardant material for the treatment of coal spontaneous combustion (CSC) in underground mines. The temperature-programed experimental device and gas chromatograph were used to simulate the low-temperature oxidation process of coal.
