Opis:: The paper presents results of investigations of a novel method for diesel exhaust filtration in a fibrous filter supplemented by the external electrostatic field (FEF), which may be used to eliminate the occupational hazard near sources of diesel emission. The reported research follows the preliminary basic study of soot removal in such systems (Ciach, Sosnowski, & Podgorski, 1995), and is focused on the construction and testing of a prototype technical-scale FEF device. The results suggest a strong relation between applied voltage and filtration efficiency of the system and demonstrate the influence of aerosol precharging on the efficiency, which can be more than 95%.

Opis:: Physicochemical techniques used for evaluating the pulmonary surfactant (PS) quality are discussed as methods useful in assessing toxicity of inhaled gases and particles. Two standard devices, Langmuir-Wilhelmy film balance and pulsating bubble apparatus, are presented in detail, and the measured results of interaction between sulfuric acid and 2 models of PS material are analyzed. The evident decrease in surface activity of the pulmonary surfactant after its contact with the acid at concentrations approaching 0.001 M may be considered as an indicator of the adverse effect, which can result in several health problems. The presented approach can be used as a method of assessing pulmonary toxicity of any substances present in the breathing air.

Tytuł:: Aerosol Generation and Identification for Model Studies of Particle–Lung Interactions
Autorzy:: Kondej, D.
Sosnowski, T. R.
Powiązania:: https://bibliotekanauki.pl/articles/90513.pdf
Data publikacji:: 2010
Wydawca:: Centralny Instytut Ochrony Pracy
Tematy:: industrial aerosols

Opis:: This article discusses the idea and set-up of a laboratory system for generating reproducible concentrated occupational aerosols containing metal compounds. Dust representatives for 2 metal-machining workstations (an electric grinder and an electric disc cutter) were released from a fluidized-bed generator, and then sampled and compared in respect to concentration, particle size distribution, particle morphology and the content of metal elements (Fe, Al, Cu, Mn, Cr, Ni, Pb, Zn, Mg). The results indicate the presence of a significant number of irregularly-shaped respirable particles. Those particles contained mainly Fe and Al, and their composition was shown to depend on particle size. The proposed system of aerosol generation and collection can be used in studies of interactions between airborne particles and a model lung surfactant.

Opis:: Aerosols of a physiological salt solution and aqueous solutions of salbutamol, sodium cromoglicate, and dornase aifa were generated in a pneumatic nebulizer and analyzed in a system with controlled humidity of air as a carrier gas. Mass distribution of aerosol particles and yield of generation for pulse nebulization were measured. Pulsation of generation was realized with an attachment maintained by a computer program. Opening times of the valve were in the range 50-800 ms. The results indicate the possibility of improving aerosol particle delivery to the lung using a pulse generation system.

Tytuł:: Experimental Evaluation of the Importance of the Pulmonary Surfactant for Oxygen Transfer Rate in Human Lungs
Autorzy:: Sosnowski, T. R.

Powiązania:: https://bibliotekanauki.pl/articles/90981.pdf

Opis:: The rate of oxygen transport from atmospheric air into water and perfluorocarbon compound (PFC) was investigated. Static and dynamic systems with and without the presence of the lung surfactant monolayer were considered. For the case of water used as an oxygen absorbent, the monolayer activity allowed a simulation of the gas uptake into the lung hypophase. In the second case, a two-phase liquid system with water as a hypophase and PFC as the blood substitute simulated oxygen transport in the alveolus-blood system. Original experimental measurement devices gave the opportunity of determining the gas transport rate with the possibilities of indicating the role of the lung surfactant in the process and evaluating the influence of environmental conditions on the transport phenomena. Results of that work suggest a possible enhancing role of the lung surfactant in the oxygen transfer rate.
