Airborne Endotoxins Detection in Offices

Sources: RNSA Laboratoire, France


Endotoxin is a structural component produced by Gram negative bacteria which are common in the environment, particularly in water or in water damaged conditions It has been associated with many respiratory symptoms and complaints related to the indoor environment including agricultural industrial sites, waste processing, and offices.

RNSA Laboratoire has been requested to do an audit about the air quality in offices where employees suffer from specific symptoms. The objective was to measure the level of exposure to
endotoxins in various spaces (Lobbies (L) meeting rooms (MR) offices (O) and open spaces (OS)).

Comparison sampling with the Coriolis®μ has been carried out in October 2009 between suspect areas and non-suspect ones under similar environmental conditions. The collected endotoxins were analyzed by the standard analytical method, LAL assay (Limulus amebocyte lysate).
