The phenomenon of combustible dust explosions is present within many industries. Tests for explosibility of dust clouds per ASTM E1226 use a 20 L explosive chamber that places the combustible dust directly below the dispersion nozzle which generates a thorough mixture for testing purposes. However, in the underground coal mining industry, there are a number of geologic, mining, and regulatory factors that change the deposition scheme of combustible coal dust. This causes the atmosphere of a coal mine to have a variable rock dust-coal dust mixture at the time of ignition. To investigate the impact of this variable atmosphere, a series of lean explosibility tests were conducted on a sample of Pittsburgh Pulverized coal dust. These explosibility tests were conducted in a 38 L chamber with a 5 kJ Sobbe igniter. The 38 L chamber generates a variable air-dust mixture prior to ignition. The test results indicate that the 38 L chamber experiences reduced explosive pressures, and lower explosibility index values when compared to the 20 L chamber.

Research discussing potential environmental toxins that may be related to the etiology of childhood leukemia has been growing. The suspected environmental contaminants include solvents, air pollutants, pesticides, and tobacco smoke. Exposure to various pesticides has come under particular scrutiny, with positive associations with childhood leukemia [1]. Poynter et al. [2] conducted a population-based study assessing the association between self-reported chemical exposures and odds of acute myeloid leukemia (AML) and myelodysplastic syndromes(MDS).
