Table 3 Substances identified as readily biodegradable and Persistent in water in the preliminary data set but excluded from the final data set and the rationale for the quality screen failure
Substance CAS (EC) | Reason for elimination from final data set |
|---|---|
Phenol 108-95-2 (203-632-7) | The simulation study was incorrectly reported as a guideline simulation study. This study was designed to assess anaerobic biodegradation of several compounds, including phenol, under stringent conditions using secondary activated sludge. No half-life was derived |
Sodium o-isobutyl dithiocarbonate 25,306-75-6 (246-805-2) Sodium o-isopentyl dithiocarbonate 2540-36-5 (807-374-1) | For both substances, the simulation study was incorrectly reported as following a guideline for simulation test and refers to hydrolysis (abiotic degradation); hence, it is not truly a simulation test. The half-life of xanthates has been reported in literature as 2–8 days in water; therefore, these substances are most likely not Persistent [1] |
2,2′-Iminodiethylamine 111-40-0 (203-865-4) | Test conducted in 1987 and incorrectly reported as a guideline simulation test. Limited details indicate it may have been a modified US EPA test method but no further details available to confirm |
