Microbiological Contamination of Hospital Air [PDF]
Applied Microbiology, 1962 The levels of airborne contamination in various areas of two hospitals were determined during a 15-month sampling period, using Casella and Andersen volumetric samplers. Based on nearly 5,000 samples, the mean count per ft 3 ranged from 4.5 in obstetric-gynecology delivery rooms to 72.4 in waste-handling areas.

Microbiological Agents As Health Risks in Indoor Air [PDF]
Environmental Health Perspectives, 1991 Ambient air may be contaminated with or carry significant levels of a variety of potentially harmful microorganisms. There are three major sources of such microbes: a) those arising from microbial decomposition of various substrates associated with particular occupations (e.g., "moldy" hay leading to hypersensitivity pneumonitis), b) those associated ...

The Microbiology of the Upper Air. II [PDF]
Journal of Bacteriology, 1935 The collection of micro-organisms from the air at various altitudes has interested observers for a considerable time. Pasteur, one of the first workers in this field, made investigations by climbing the Alps to obtain his samples. More recently the airplane has made it possible for others to make studies on the micro-organisms found in the upper air ...

Microbiological Evaluation of a Large-Volume Air Incinerator [PDF]
Applied Microbiology, 1968 Two semiportable metal air incinerators, each with a capacity of 1,000 to 2,200 standard ft 3 of air per min, were constructed to sterilize infectious aerosols created for investigative work in a microbiological laboratory.

QuEChER method for air microbiological monitoring in hospital environments
The Journal of Infection in Developing Countries, 2020 Introduction: Nosocomial pathogens have become a priority issue for public health, since they are responsible for increased morbidity and mortality in hospitalized patients and the development of multi-resistant microorganisms, as well. Recent studies found strong evidence that airborne transmission plays a key role in many nosocomial infections. Thus,

Sensitive Microbiological Detector for Air Pollution [PDF]
Nature, 1968 THERE is an extensive literature on the photochemical reactions involved in the production of smog, which is reviewed in refs. 1. and 2. Early investigations of this problem3–5 revealed that at extremely low concentrations the oxidative constituents could damage the leaves of certain plants, and that differences in the leaf damage of plants at ...

Microbiological disinfection of water and air by photocatalysis
Comptes Rendus. Chimie, 2007 This article is aimed at presenting (i) a fundamental research on the efficiency of photocatalysis in water disinfection and (ii) the efficiency of a photocatalytic prototype, developed by Buxair firm, to remove avian influenza virus in air. In water disinfection, two model strains of Escherichia coli (K12 PHL849 and K12 PHL1273) were selected and a ...

Markers of Chemical and Microbiological Contamination of the Air in the Sport Centers
Molecules, 2023 This study aimed to assess the markers of chemical and microbiological contamination of the air at sport centers (e.g., the fitness center in Poland) including the determination of particulate matter, CO2, formaldehyde (DustTrak™ DRX Aerosol Monitor; Multi-functional Air Quality Detector), volatile organic compound (VOC) concentration (headspace solid ...

Indoor Microbiological air Pollution in the Hospital
Quality of Life (Banja Luka) - APEIRON, 2020 Microorganisms in the air of occupational indoor environments are associated with a wide range of adverse health effects with major public health impact. The aim of this study was testing the presence of microbiological parameters (bacteria and fungi) and microclimatic parameters (temperature and relative humidity) in the clinical hospital “St.
