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…

Introduction 1 Over the past 50 years, the prevalence of allergic respiratory diseases has been increasing. The Hygiene hypothesis explains this progression by the decrease in the bio-diversity of early microbial exposure. This study aims…

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…

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…

Endotoxins are constituents of the outer membrane of certain bacteria which can be suspended in the air during occupational tasks. The previous measurement method dated from 2005 and needed updating. A complementary laboratory and field approach…

This method describes the Active cassette sampling and spectrophotometric analysis of the substance(s): Endotoxins

Endotoxins are components of the outer membrane of certain bacteria that can become airborne during certain aerosol-generating work activities and cause adverse effects on workers health. Filtration is the sampling method recommended…

The measurement of airborne endotoxins is often necessary because of the inhalation of these lipopolysaccharides from most Gram-negative bacteria is known to provoke harmful effects on worker s health including acute respiratory symptoms…
