Microbial Exposure Assessment in Sawmill, Livestock Feed Industry, and Metal Working Fluids Handling Industry
OBJECTIVES The objective of this study is to investigate the distribution patterns and exposure concentrations of bioaerosols in industries suspected to have high levels of bioaerosol exposure. METHODS We selected 11 plants including 3 livestock feed plants (LF industry), 3 metal working fluids handling plants (MWFs industry), and 5 sawmills and measured total airborne bacteria, fungi, endoto...
متن کاملExposure to grain dust and microbial components in the Norwegian grain and compound feed industry.
OBJECTIVES The aim of this study was to extensively characterize grain workers' personal exposure during work in Norwegian grain elevators and compound feed mills, to identify differences in exposures between the workplaces and seasons, and to study the correlations between different microbial components. METHODS Samples of airborne dust (n = 166) were collected by full-shift personal samplin...
متن کاملLife Cycle Assessment of Concentrate Feed Supply System for Japanese Domestic Livestock Industry
The objectives of this presentation are to evaluate and compare the environmental burdens of the two different concentrate feed supply systems to Japanese domestic livestock industry. Life-Cycle Assessment (LCA) method is used on the two systems such as the conventional system depending on US-imported corn and the proposed new system. Japanese domestic livestock industry could reduce 78,462 ton...
متن کاملMicrobial growth and accumulation in industrial metal-working fluids.
The dynamics of microbial growth in metal-working fluids (MWF) and the effect of the addition of biocides were studied in large fluid systems, in this case, one central tank which holds 150 m3. In this system, populations of Pseudomonas pseudoalcaligenes (greater than 10(8) CFU/ml) were sustained for a year, although large quantities of biocides were added. Quantitation of 3-OH lauric acid, a m...
متن کاملStatistical Modeling for Process Control in the Sawmill Industry
Softwood logs are processed into green boards through a series of horizontal or vertical sawing operations that reduce lumber thickness. This paper uses physical understanding to model how systematic and random errors in board thickness accumulate during sequential resawing. The error model is validated on board thickness measurements gathered at a northern California sawmill. The analysis • ex...
