We developed and tested a new method for in situ characterization and distribution of inorganic particles in biopsied lung tissue from three diverse human subject groups using field emission scanning electron microscopy with an energy dispersive analyzer. Backscattered electron and secondary electron images of particulate matter in lung tissue were acquired. Inorganic particulate matter in the field of view of the image was analyzed using energy dispersive spectroscopy and subsequently identified and cataloged.

This article is the first part of a study dealing with current and prospective clean coal technologies. For this purpose, the importance of coal utilization in electricity production and the importance of clean coal technologies (CCTs) for the minimization of the environmental impacts of coal-fired power generation are discussed as an introduction to the subject. The article includes an extensive presentation about the source and formation mechanisms of the major pollutants and their control strategies.

Atmospheric particulate matter (PM) is a heterogeneous material. Though regulated as un-speciated mass, it exerts most effects on vegetation and ecosystems by virtue of the mass loading of its chemical constituents. As this varies temporally and spatially, prediction of regional impacts remains difficult. Deposition of PM to vegetated surfaces depends on the size distribution of the particles and, to a lesser extent, on the chemistry. However, chemical loading of an ecosystem may be determined by the size distribution as different constituents dominate different size fractions. Coating with dust may cause abrasion and radiative heating, and may reduce the photosynthetically active photon flux reaching the photosynthetic...

We developed and tested a new method for in situ characterization and distribution of inorganic particles in biopsied lung tissue from three diverse human subject groups using field emission scanning electron microscopy with an energy dispersive analyzer. A backscattered electron image of each frame was acquired to locate inorganic particulate matter. The electron beam was deflected to points on the particles in the field of view to acquire an energy dispersive spectrum. The acquired spectra were used to identify the particle type.

We developed and tested a new method for in situ characterization and distribution of inorganic particles in biopsied lung tissue from three diverse human subject groups using field emission scanning electron microscopy with an energy dispersive analyzer. The ICP-MS data table provides the concentrations of elements (in parts per billion) analyzed in the filtrate solutions from the tissue digestion method. This step was done to help determine if the phases identified during the in situ examination might dissolve during tissue digestion in a bleach solution.
We developed and tested a new method for in situ characterization and distribution of inorganic particles in biopsied lung tissue from three diverse human subject groups using field emission scanning electron microscopy with an energy dispersive analyzer. This library of phase spectra is provided to show the typical energy dispersive spectrum of the inorganic particulate matter identified in lung biopsy sections.
We developed and tested a new method for in situ characterization and distribution of inorganic particles in biopsied lung tissue from three diverse human subject groups using field emission scanning electron microscopy with an energy dispersive analyzer. The following .csv files summarize the inorganic particle identifications made in each frame of each area for each subject in the study. The In_Situ_Frame_Summary_2016-09-09_NJH***.csv is a tabulation of the phases identified in each frame. The In Situ Area Summary_2016-09-09.csv totals the number of times each phase was identified in an area of the lung tissue biopsy for each subject from the In_Situ_Frame_Summary_2016-09-09_NJH***.csv.

We developed and tested a new method for in situ characterization and distribution of inorganic particles in biopsied lung tissue from three diverse human subject groups using field emission scanning electron microscopy with an energy dispersive analyzer. Secondary and backscattered electron images were acquired to document the size and location of inorganic particulate matter in areas of lung tissue biopsy sections.
