Applicant's summary and conclusion

Interpretation of results:
readily biodegradable
Conclusions:
5-hydroxyisopthalic acid is 50% biodegradable in water in 15 days (half-life) indicating 5-hydroxyisopthalic acid is readily biodegradable in water since the half life is less than the threshold of 60 days (to qualify the chemical as persistent)
Executive summary:

5-hydroxyisopthalic acid is 50% biodegradable in water in 15 days (half-life) indicating 5-hydroxyisopthalic acid is readily biodegradable in water since the half life is less than the threshold of 60 days (to qualify the chemical as persistent)
