Endpoint summary

Administrative data

Description of key information

Adsorption/desorption

Based upon a calculated log Koc adsorption to solid soil phase is not expected. The log Koc value was determined to be 1 and the Koc value was determined to be 10.

 

Henry´s Law constant

From the water surface the substance will not evaporate into the atmosphere.

Distribution modelling

From the water surface the substance will not evaporate into the atmosphere. The substance will preferentially distribute into the compartment water.

Additional information

Adsorption/desorption

A QSAR estimation was performed to fulfill this endpoint. KOCWIN version 2.00 was used as model with the the MCI and Kow method to calculate the Koc value. The Koc value was determined to be 10, the log Koc was determined to be 1 with the MCI method. The calculated Koc in the Kow method was 0.002104 L/kg, the calculated log Koc value was -2.6770. As a worst case presumption the Koc value was determined to be 10 and the log Koc value was determined to be 1.

Henry´s Law constant

Henry´s law constant at 25°C was estimated to be 1.09E-006 Pa*m3/mole by SRC HENRYWIN v3.20 .

Distribution modelling

From the water surface the substance will not evaporate into the atmosphere. The substance will preferentially distribute into the compartment water.
