The content of test item dissolved in the water sample was 7.44 g/L.
Main Study
The results for the samples taken at 24, 48 and 72 hours are given inTable below.
The maximum difference of the concentrations determined in the 24, 48 and 72 hour test samples was≤ 15%. Based on this, the water solubility of the test item is given as the mean value of the analyzed concentrations.
No test item was detected in the pretreated sample from the blank water mixture.
