What is it about?
Exposure to endotoxins, important biological components of airborne particulate matter (PM), is reported to have adverse effects on human health. This study showed the endotoxin concentrations in fine (PM2.5) and coarse (PM10–2.5) particulate matter collected inside and outside homes in an urban city

Why is it important?
For both PM2.5 and PM10–2.5, indoor endotoxins may arise from indoor sources in addition to the infiltration from outdoor air. The household factors associated with indoor endotoxin concentrations are considered to be different depending on the particle size fractions.
Perspectives
Further studies with larger samples and longer sampling periods are necessary for the more detailed evaluation of the predictors of indoor endotoxin concentrations.
