- •
E. coli-based whole-cell bioreporter (WCB) was developed to detect arsenic in soil.
- •
The WCB expressed GFP under the control of an arsenic-responsive promoter.
- •
Soil samples artificially and naturally contaminated with arsenic were tested.
- •
The WCB was sensitive, detecting arsenic present in the parts per billion range.
- •
The WCB showed that soil washing reduced total but not bioavailable arsenic.
