During wastewater treatment, bioaerosols are generated and, can either remain in suspension for several hours or settle on surfaces and workers may be exposed. The presence of pathogens in the air could contribute to an increased frequency of gastrointestinal or respiratory illness amongst workers. Due to harsh winter conditions in Eastern Canada,...

Le traitement des eaux usées comporte plusieurs étapes susceptibles de générer des bioaérosols auxquels des travailleurs peuvent être exposés. Bien que la littérature à ce sujet soit relativement abondante, les connaissances relatives au risque, à l’exposition et à la fréquence de certaines maladies chez cette population demeurent mal documentées....

Bioaerosols are among the less studied particles in the environment. The lack of standardization in sampling procedures, difficulties related to the effect of sampling processes on the integrity of microorganisms, and challenges associated with the application of environmental microbiology analyses and molecular and culture methods frighten many yo...

Aerosol collection can be achieved through a myriad of techniques. These techniques can be used to select aerosols based on their size and nature. Typical techniques include passive sampling, air filtration, liquid- or solid-phase inertial impaction, and electrostatic sampling. The sampling method selected must be guided by the scientific questions...

Particles of biological origin can represent a large fraction of suspended particulate matter, often more than half of all particles by mass, and exist at a range of sizes from tens of nanometers to hundreds of microns. They are present in every corner of the globe and above every type of ecosystem, even up to tens of kilometers in altitude. Bioaer...

Biological aerosols have specificities that can allow them to be detected within a mixed population of particles. These specificities can also enable biological aerosols to be quantified and characterized, by means of a well-defined shape, autofluorescence, capacity to multiply on a culture medium, genetic information, etc. The methods used in aero...

Wastewater treatment center (WTC) workers may be vulnerable to diseases caused by viruses, such as the common cold, influenza and gastro-intestinal infections. Although there is a substantial body of literature characterizing the microbial community found in wastewater, only a few studies have characterized the viral component of WTC aerosols, desp...
