“…This concentration range is comparable with those reported in other studies that have investigated ambient endotoxin concentrations in various countries (i.e., USA, Germany, Sweden, and Hong Kong) (Mueller-Anneling et al, 2004;Morgenstern et al, 2005;Tager et al, 2010;Nilsson et al, 2011;Cheng et al, 2012). However, the concentration range observed in the present study was lower than those reported in previous studies conducted in occupational settings, wherein the measurements were generally performed at the sources of endotoxins (Su et al, 2002;Madsen and Nielsen, 2010;Rimac et al, 2010).…”

“…LPS are fairly heat stable and normally are not affected by usual sterilization processes (Milton 1999;Pommerville, 2011). Several studies have demonstrated that endotoxins can be detected in the ambient air by using various types of collection methods, such as filter cassettes connected to personal pumps, high volume samplers, and impingers (Macher, 1999;Su et al, 2002;Adhikari et al, 2011;Cheng et al, 2012).…”

Ambient bacteria and endotoxins are components of bioaerosols, which are abundant in ambient air. Exposure to ambient bacteria and endotoxins has been associated with respiratory symptoms. We monitored the spatiotemporal distributions of ambient bioaerosols in the Greater Taipei area by using multisite sampling and developed regression models for ambient bacterial and endotoxin concentrations. Forty-four representative sampling sites were selected from the Greater Taipei area. Samples were collected in 4 seasons throughout a 1-y study period. Ambient bacteria were quantified using acridine orange staining, and endotoxins were analyzed using Limulus amebocyte lysate assays. Land-use types and major determinants of the bioaerosols were used to develop regression models. Ambient bacteria ranged from < limit of detection (LOD) to 1.68 × 10 5 cells/m 3 , whereas endotoxins ranged from < LOD to 20.62 EU/m 3 . Significant seasonal variations were observed for both bioaerosols, with the highest concentrations observed in spring. Regression analyses revealed temperature, relative humidity, and particulate matter as the major predictors of ambient bacteria and endotoxins. No land-use type was correlated with any of the bioaerosols. The number of schools and gas stations was positively associated with both bioaerosols. The leave-one-out cross-validation R 2 of the final models for ambient bacteria and endotoxins were 0.11 and 0.31, respectively. The results of this study revealed high spatiotemporal variations in the distributions of ambient bacteria and endotoxins in the Greater Taipei area. Additional potential predictors should be included in future studies to develop better predictive models for ambient bacteria and endotoxins.

“…Endotoxin is a contaminant of cotton dust and the exposure is higher in cotton mills as compared to other industries with organic dusts such as tea packing or tobacco factories 4 – 6. Although measurements of endotoxin levels in cotton mills have been performed in many studies, none of the earlier investigations reporting a reduced risk for lung cancer had endotoxin exposure data in their study design.…”
