Table 2.
Tap water supplemented with arsenite and treated landfill leachate from AnDMBRs were used to assess the efficacy of the whole-cell biosensor and to compare its sensitivity to AFS. The relative difference was calculated as follows: relative difference = [(result by biosensor - result by AFS)/result by AFS] × 100%.
| Source of sample | Results by AFS (μM) | Results by biosensor (μM) | Relative difference (%) |
|---|---|---|---|
| Polluted tap water 1 | 0.039 | 0.036 | −7 |
| Polluted tap water 2 | 0.058 | 0.054 | −7 |
| Polluted tap water 3 | 0.092 | 0.088 | −4 |
| Treated leachate 1 | 0.059 | 0.056 | −5 |
| Treated leachate 2 | 0.043 | 0.045 | +6 |
| Treated leachate 3 | 0.068 | 0.070 | +3 |
