Concentrations of endotoxin in urban air pollution have not previously been extensively
characterized. We measured 24-hr levels of PM10 (particulate matter< 10 microm in
aerodynamic diameter) and the associated endotoxin component once every 6 weeks for 1
year in 13 communities in Southern California. All the samples collected had detectable
PM10 and endotoxin levels. The geometric mean PM10 was 34.6 microg/m3 [geometric SD
(GSD), 2.1; range, 3.0-135]. By volume, the endotoxin geometric mean was 0.44 endotoxin …
