Table 4
Toxicity criteria according to AVS, SEM and TOC. (Adapted from [
8]).
| SEM, AVS, and TOC relationship | Toxicity criteria |
| < 130 | Toxicity is not likely due to Cd, Cu, Pb, Ni, and Zn. | 130 < < 3000 | Toxicity is uncertain due to Cd, Cu, Pb, Ni, and Zn. | > 3000 | Toxicity is likely due to Cd, Cu, Pb, Ni, and Zn. | − AVS ≤ 0 | Nontoxic. |

When − AVS > 0, organic carbon has to be taken into account according to the expressions in Table 4.
