Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

The Economic Journal, EarlyView., 2018
The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Study on airflow-coal dust dispersion pattern and control technology in fully mechanized mining face

Gong-kuang zidonghua
The shearer in a fully mechanized mining face generates significant turbulent airflow during coal cutting, resulting in changes in airflow velocity in the mining area and causing the lateral dispersion of coal dust particles toward pavements.

Chemical Recycling as a Tool for Enabling a Second Life for Polyesters

SusMat, EarlyView.
This review presents the elucidation of the life cycle of main polyesters, detailing end‐of‐life methods, with focus of solvolysis technologies, then an analysis of LCA and TEA on literature data, an original data analytic, and, finally, a current industrial mapping of the main processes with a critical perspective on the plastic life‐cycle ecosystem ...

Experimental study on characteristics of methane-coal dust explosions and the spatiotemporal evolution of flow field in early flame

Case Studies in Thermal Engineering
To understand the explosion characteristics of methane-lignite coal dust mixtures and the spatiotemporal evolution of the early flame flow field, explosion pressure, OH* emission spectra, and early flame schlieren images were captured in a 60L constant ...

Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

The UK Clean Air Act at 70: An interdisciplinary analysis of historical air quality change

Weather, EarlyView.
2026 marks the 70th anniversary of the first UK Clean Air Act, a pivotal moment for air quality in modern British history. Previous narratives on this legislation have largely centred on pollution in London and monodisciplinary perspectives. This article integrates historical research with reconstructed estimates of PM2.5 concentrations to spotlight ...

Study on flame fractal characteristics of coal dust explosion at the decompression position of Hartmann tube

Scientific Reports
The explosion of coal dust is powerful and has a wide range of spread, which can easily cause mass death and injury. In this paper, the flame microstructure and propagation characteristics of coal dust explosion are recorded by high-speed photography ...

Experimental research on microbial dust suppressant for solidified dust based on MICP

Meikuang Anquan
In order to reduce the concentration of coal dust in open-pit coal mines, reduce and prevent the harm of coal dust, based on the microbial induced calcite precipitation solidification dust technology, the influence of environmental factors（temperature ...

In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy

Journal of Synchrotron Radiation, EarlyView.
For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

Transcriptional breakpoints as predictors of thermal thresholds in a climate‐impacted stenothermal fish

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The biogeography of ectotherms is greatly influenced by their thermal tolerance, which is expected to be tightly coupled to aerobic performance. However, preferred temperatures of ectotherms often deviate substantially from aerobic performance optima. This suggests that
