PM10-BOUND HEAVY METAL CONCENTRATIONS AND THE HUMAN HEALTH RISK ASSESSMENT FROM ONE OF THE WORLD’S LARGEST MULTIPLE OPEN-PIT COAL MINES

, 2020
This study was designed to evaluate the atmospheric total particulate matter (PM10) concentrations, PM10-bound heavy metal concentrations and the human health risk assessment from one of the world’s largest multiple open-pit coal mines (Region La Guajira

‘Elbow grease and yellow soap’: Housework time in working‐class households in late‐nineteenth and early twentieth‐century Britain

The Economic History Review, EarlyView.
Abstract Housework is central to feminist calls for recognition of women's work, economic histories explaining the sexual division of labour, and claims regarding the progressive role of scientific knowledge. Yet little is known about the time it actually took. We address this lacuna.

When Density Matters: Hydraulic and Salinity Evolution in Groundwater‐Fed Pit Lakes in Semiarid and Arid Climates

Groundwater, EarlyView.
Pit lakes in semiarid and arid regions are often assumed to be terminal sinks for groundwater following mine closure. Using synthetic numerical modeling, we demonstrate that evaporation‐driven density gradients can reverse this behavior, transforming pit lakes into throughflow systems and potentially increasing salinity in adjacent aquifers.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Advances in reconstruction of coal micro-nano structure and its application in water injection seepage mechanisms

Meitan kexue jishu
Coal seam water injection is a key technology for source control of hazards such as dust and gas. The complex pore-fracture structure within the coal mass directly determines the effectiveness of water injection, making it essential to clarify the ...

The Industrial Organization of Regulatory Capture

Social Science Quarterly, Volume 107, Issue 4, July 2026.
ABSTRACT Objective This study evaluates the role that the economic organization of an industry plays in its ability to successfully pressure government regulators for laxer enforcement Methods The effect of the industrial organization of the coal mining industry on environmental regulation is assessed using pooled cross‐sectional time‐series analyses ...

Width optimization of water-sealing coal-rock barrier pillar along irregular boundaries of clinker in open-pit coal mines

Meitan kexue jishu
Due to the shallow burial depth and complex geological conditions of coal seams in some open-pit coal mines, coal seams are often exposed and in full contact with air, leading to spontaneous combustion and the formation of burnt rock. Burnt rock contains

Go/Zrp as an Effective Adsorbent for Pb(II) Ions Removal From Water: Preparation, Adsorption Behavior, and Equilibrium Studies

ChemNanoMat, Volume 12, Issue 6, June 2026.
Contaminated water, especially with heavy metals like lead (Pb(II)), poses significant risks to both ecosystems and human health. This study explores effective materials for removing Pb(II) ions from water, focusing on graphene oxide (GO)‐based nanocomposites known for their high adsorption capacity.

Carbon footprint and atmospheric pollutant emissions accounting of an open-pit coal mine in China and its reduction pathways

Meitan xuebao
The coal industry is a key area for pollution reduction and carbon mitigation in China. Clarifying the emission characteristics of CO2 and air pollutants during the coal mining process is crucial for achieving carbon peak and carbon neutrality. A typical

Multi‐omics reveals a novel Cxcr4+ subpopulation of alveolar macrophages and therapeutic effect of AMD3100 in mice with advanced silicosis

Clinical and Translational Medicine, Volume 16, Issue 6, June 2026.
The progression of silicosis‐associated fibrosis relies on a positive feedback loop mediated by crosstalk between Cxcr4+ macrophages and Cxcl12+ fibroblasts and the therapeutic potential of targeting the Cxcl12/Cxcr4 axis with AMD3100 as a novel strategy for treating silicosis.
