Endotoxin and viable counts, shown as median (range)
| Surface Median (min–max) | Floor Median (min–max) | Ventilation outlets Median (min–max) | |
|---|---|---|---|
| Spearman’s rank correlation coefficient (rs) is given where significant positive correlation is found between viable counts and PF in the rank correlation test. Modified from Allermann and Poulsen.13 | |||
| Endotoxin (EU/mg dust) | 59 (9.3–204) | 72 (10–195) | 12 (1.4–64) |
| rs=0.31 | rs=0.07 | No correlation | |
| Actinomycetes (cfu/mg dust) | 8.1 (0.1–357) | 28 (0.6–2402) | 0.6 (0.6–21) |
| No correlation | No correlation | rs=0.14 | |
| Bacteria (cfu/mg dust) | 1185 (335–4790) | 2072 (10–21840) | 65 (0.6–33348) |
| No correlation | rs=0.14 | rs=0.01 | |
| Mould (cfu/mg dust) | 69 (16–411) | 31 (1.1–400) | 12 (0.6–1310) |
