Limits of detection (LOD) and quantification (LOQ) of the analytical air monitoring (µg/m3) and biomonitoring (µg/l) methods
| Air monitoring | Biomonitoring | |
|---|---|---|
| LOQ* [µg/m3] | LOQ (LOD) [µg/l] | |
| Aluminium | 0.17 | 3.0 (1.0) |
| Antimony | 0.17 | 1.0 (0.3) |
| Arsenic | 0.027 | 6.0 (2.0) |
| Beryllium | 0.0017 | 0.09 (0.03) |
| Cadmium | 0.017 | 0.50 (0.16) |
| Chromium | 0.21 | 0.50 (0.16) |
| Cobalt | 0.083 | 1.0 (0.3) |
| Nickel | 0.39 | 1.0 (0.3) |
| Mercury | 0.013; 0.02# | 0.6 (0.2) |
Detailed description of methods for LOD/LOQ determination in the “Laboratory analytics” section
*Air monitoring LOQs depend on the air volume sampled (standard 10 l/min, 2 h) and may differ on a daily basis e.g. in case of prolonged sampling times (4 to 6 h in the present study)
