(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…

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…

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…

A study was carried out at a waste sorting centre in France processing dry recyclable household waste and dry recyclable commercial and industrial waste. The aim was to study exposure to bioaerosols and dust. The results confirm that waste and…

Unlike sporulating microorganisms (fungi, actinomycetes), more fragile microorganisms (bacteria) cannot be sampled by filtration because they are sensitive to the stress of the sampling. The objectives of the study are to choose, to assess, and…

Assessing the risks related to occupational exposure to bioaerosols involves deploying appropriate methods and strategies. Most of the studies for assessing exposure to bioaerosols at the work station in various sectors of occupational…

(1,3)--D-glucans are polysaccharides from biological origin that may become airborne particles during normal working operations with contaminated materials. Exposure to airborne (1,3)--D-glucans are assumed to induce work related respiratory…

The enumeration of bioaerosols on culture media is a low-cost method that is easy to set up and is still the benchmark for studying bioaerosols in workplace air. However, developments in scientific knowledge and feedback from users indicate…
