Investigations of air pollution were carried out in Trbovlje, Zagorje and Hrastnik, three towns in the Zasavje urban region in Slovenia with its dense industry. This region has a typical geographic location in small, closed side valleys of the Sava river. Special pumps were equipped with a Nucleopore-Costar polycarbonate membrane filters (pore size 0.4 ĵ m) to determine cadmium and lead in resp...

Effect of respirable fly ash particles inhalation on lungs of rats was investigated by exposing them to respirable aerosols of size classified power plant fly ash at average concentrations of up to 14.4 +/- 1.77 mg/m3 for 4 hr/day for 28 consecutive days. A remarkable increase was found in blood eosinophil counts of fly ash exposed animals. Biochemical indicators of pulmonary damage viz. lactat...

The aim of this study was to determine the influence transport on concentration carbon species in aerosols collected coastal zone Gulf Gdansk period outside heating season. Elemental (EC), organic (OC), and ?PAHs5 concentrations were measured two size: <3 ?m (respirable aerosols) >3 diameter (inhalable aerosols). Samples between 13 July 2015 22 (holiday period) 14 September 30 (school per...

Aerosol particle size influences airway drug deposition. Current inhaler devices are inefficient, delivering a heterodisperse distribution of drug particle sizes where, at best, 20% reaches the lungs. Monodisperse aerosols are the appropriate research tools to investigate basic aerosol science concepts within the human airways. We hypothesized that engineering such aerosols of albuterol would i...

This study investigated the relationships between particle number, surface area, and respirable mass concentration measured simultaneously in a foundry and an automotive engine machining and assembly center. Aerosol concentrations were measured throughout each plant with a condensation particle counter for number concentration, a diffusion charger for active surface area concentration, and an o...

Air samples were collected to examine physical and chemical characteristics of lead aerosols in different work environments in the airborne lead concentration range from 28-783 micrograms/m3. Size distribution of aerosols was measured using a Marple personal cascade impactor, and lead analysis was conducted using graphite atomic absorption spectrometry. Lead aerosol size distribution was found ...

Uranium aerosols are released from uranium-containing materials in high-temperature environments caused by nuclear accidents or other processes. Research on the generation characteristics of uranium under such conditions is an important part nuclear-safety analysis. In this experiment, similarity between metal cerium and material was evaluated aspects particle size distribution source term. Com...

An extensive literature review of published metalworking fluid (MWF) aerosol measurement data was conducted to identify the major determinants that may affect exposure to aerosol fractions (total or inhalable, thoracic and respirable) and mass median diameters (MMDs). The identification of determinants was conducted through published studies and analysis of published measurement levels. For the...
