The aim of this article is to present an overview of endotoxin concentration levels recorded over more than eleven years in various sectors of activity in France. The use of these exposure levels helps to support the two endotoxin guideline values…

(1,3)-B-D-glucans are compounds of biological origin (moulds, yeast, plants, certain bacteria). They may be present in the workplace air and can represent a toxinic risk for exposed workers.

The objectives of the study are to develop and to assess a method…

Bioaerosol emitted by working activities in Waste Sorting Plants (WSP) were associated with several health disorders such as rhinitis, asthma and hypersensitivity pneumonitis. The aim of the study was to investigate the exposure to airborne…

Noting that a new version of the cup was now commercialised and the assumption that the use of viscous liquids, not evaporating, could increase the sampling duration and modify the physical performances, the objective of this work was to characterize…

The CIP 10-M personal sampler is used to assess worker exposure to airborne particles by collecting them in a rotating metal cup containing a few milliliters of a collection fluid. Although used by many teams in the world, the particle-collection…

Waste sorting activities are source of occupational bioaerosol exposure that was associated with several health disorders such as rhinitis, asthma and hypersensitivity pneumonitis. So far, the microbial biodiversity data published in this…

Endotoxins are lipopolysaccharides present in the outer membrane of most Gram-negative bacteria. They can become airborne by working tasks, techniques and processes that generate aerosols from materials contaminated by these microorganisms…

Because of their ability to measure short-term fluctuations, photometers are increasingly used for real-time aerosol characterization in workplace atmospheres. Despite the need for a custom calibration factor to obtain more accurate mass…

A study on the harmonization of performance evaluation protocols for bioaerosol measurement methods, initiated in partnership with two other institutes specialized in this field, is currently underway at INRS. The aim of this project is to…

Endotoxins, compounds found in the outer membrane of gram-negative bacteria, can pose a health risk to workers if inhaled. In workplaces, activities such as water jet cleaning or compost turning can lead to airborne endotoxins. In 2005, INRS proposed…
