General Comments : The data indicate that 33% of the material degrades in the 10-day time<br />
window in which 70% degradation must occur in order for the chemical<br />
to be classified as readily biodegradable. 70% biodegradation did not<br />
occur until day 34. The results of this test indicate, however, that the test<br />
material is unlikely to persist in the environment, but may not be fully<br />
removed during wastewater treatment.<br />
