Estimation of viable airborne microbes downwind from a point source.
Modification of the Pasquill atmospheric diffusion equations for estimating viable microbial airborne cell concentrations downwind form a continuous point source is presented. A graphical method is given to estimate the ground level cell concentration given (i) microbial death rate, (ii) mean wind speed, (iii) atmospheric stability class, (iv) downwind sample distance from the source, and (v) s...
متن کاملAirborne Respiratory Diseases and Mechanical Systems for CONTROL OF MICROBES
diseases in indoor environments remains a problem of indoor air quality (IAQ) with few engineering alternatives and for which performance goals and design parameters are unclear. The engineer who attempts to deal with microbial IAQ finds that pertinent microbiological information exists in abundance but not in easily digestible forms. This article summarizes the relevant literature of medical m...
متن کاملLice, Humans, and Microbes
Lice are small, wingless, minor ectoparasites of mammals and birds. More than 540 blood-sucking lice (Phthiraptera: Anoplura) have been described with each host having its own type of louse, suggesting the cospeciation of the lice species with their host. Among these, two lice species from two different genera infest humans: Pediculus humanus and Phthirus pubis (pubic “crab” l...

متن کاملDetection of airborne microbes in a composting facility by cultivation based and cultivation-independent methods.
Standard methods for quantification of airborne bacteria are based on cultivation and counting of grown colonies. From complex natural environments it is known that only a small fraction of the total number of cells can be cultivated on routinely used agar-media. Direct microscopic cell counting after DNA-staining usually generates higher concentrations of one to two magnitudes. The objective o...
