Application of the testing tool with TNT in 3 different soils. NER, residue and potentially bioavailable expressed as percentage of added TNT, actually bioavailable as mg/l TNT and toxicity as 100/EC20. Potentially bioavailable is calculated as difference of TNT present in soil before and after TENAX-extraction. The same Y-axis is used for all parameters. a Soil 01-A (loamy sand). b Soil 02-A (silt loam). c Soil 03-G (silt loam)
