Additional information


The HPLC method using soil-adsorption-reference data was applied for the determination of the adsorption coefficient (Koc) of 4,4'-DDS. The Koc and log Koc value of the test substance at neutral pH were respectively 57 and 1.76.


The substance has therefore a low adsorption potential.
