Understanding the Primary Particle Characteristics Affecting Dust-Induced Pulmonary Toxicity in the Modern Mine Environment

Exposure to mine dust has been recognized as a hazard for decades. The establishment of the permissible exposure limit temporarily succeeded in lowering the harmful coal dust exposure in miners. Surprisingly, a recent investigation reported an unexpected increase of the occupational pneumoconiosis and other progressive pulmonary diseases since the 2000s. The rebound shows that the mine environment is changing, which might be due to the introduction of productive equipment generating a great amount of a mixture of small particles of respirable size, including nano-sized matters. It is a high-priority to understand the exposure profile in the modern mine, also, the missing puzzles in the particle-induced toxicity pathway are essential to be explored.
