  1. Endotoxine in der Luft am Arbeitsplatz.

    Article - En allemand

    Traduction en anglais : Endotoxins in the air of workplaces.

    Endotoxins are lipopolysaccharide complexes that are integral parts of the outer cell wall of gram-negative bacteria.

    They are ubiquitous in nature and can also be found in many occupational environments up to concentrations of 40000 endotoxin units/m3 (EU/m3), e. g. in agriculture, natural products processing facilities, or waste processing.

    At the workplace the respiratory exposure to airborne dusts containing endotoxins is of special interest.

    Acute health effects after inhalation are cough, decrease in lung function, fever reactions, and malaise.

    Chronic endotoxin exposure may lead to chronic bronchitis.

    At present no occupational exposure limits have been established.

    Estimated were « No Effect Levels » for acute and chronic respiratory effects ranging from 90 to 1800 EU/m3 based on experimental as well as epidemiological studies.
