Justification for data waiving:

Justification for type of information:
The study does not need to be conducted because the HPLC method is not technically feasible for the organotin substances. On this basis, adsorption/desorption testing has been omitted.

The adsorption coefficient of the test material was calculated using KOCWIN v2.00 2000 U.S. Environmental Protection Agency. Given that the substance is slightly greater than the molecular weights in the training set, the estimate is less accurate.
The adsorption Koc of the test material was estimated to be 3415000000 L/kg.
