The application of biochar as a soil amendment is an emerging technique for low-cost remediation of contaminated soil. The high porosity and large surface area of biochar make it suitable for adsorption of contaminants such as heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs). Adsorption reduces the bio-availability of contaminants to soil microorganisms thus potentially increasing soil function and productivity. Many different biochars are available which differ in key properties such as contaminant adsorption and stability. To assess biochar performance as a soil amendment we will develop bacterial biosensors to measure contaminant bioavailability and toxicity at a cellular level. Biosensors are a complementary tool to chemical analysis.
