Reference
Endpoint:
adsorption / desorption: screening
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance has a low octanol water partition coefficient and the adsorption potential of this substance is related to this parameter
Justification for type of information:
The substance has a low potential for adsorption to soil, sludge and sediment (lLg Kow=0.55). Therefore, the study is not relevant.
Conclusions:
This study is waived. However, for the CSA, a calculated Koc is used for the assessments:

The Koc of p-TSH is calculated from the QSAR expression: Log Koc = 0.81 Log Kow + 0.10 = 3.51 L/kg 
Executive summary:

This study is waived. However, for the CSA, a calculated Koc is used for the assessments:


The Koc of p-TSH is calculated from the QSAR expression: Log Koc = 0.81 Log Kow + 0.10 = 3.51 L/kg 

Description of key information

The Koc of p-TSH is calculated from the QSAR expression: Log Koc = 0.81 Log Kow + 0.10 at 3.51 L/kg 

Key value for chemical safety assessment

Koc at 20 °C:
3.51

Additional information

The Koc of p-TSH is calculated from the QSAR expression: Log Koc = 0.81 Log Kow + 0.10 at 3.51 L/kg
