Adsorption / desorption
Administrative data
- Endpoint:
- adsorption / desorption
- Remarks:
- adsorption/desorption
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 2009-07-20 to 2009-09-20
- Reliability:

- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Adsorption/desorption test was conducted in accordance with a national standard method (China) . The test is considered to be not reliable given the test procedure and results are not fully described; e.g. there is no description of the soil parameters; no information on Log Kow and solubility of the test substance; test with blank control not fully described.

Results and discussion
Applicant's summary and conclusion
- Conclusions:
- The results of the screening experiment indicated that the adsorption rates in Changchun soil ESS-1, brown soil ESS-2 of Dalian and red soil ESS-3 of Changsha were 100% and the desorption rates from each of the three soils were 0%. However, the results are not considered to be reliable.The test procedure and results are not fully described; e.g. there is no description of the soil parameters and no information on Log Kow and solubility of the test substance which confirm the results of a 100 % of adsorption at each of the three soil types and 0% desorption as well. In addition , the test conducted withthe blank control is not fully described.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
