The aerobic biodegradation of aldona was studied in a closed bottle test according to the test guideline OECD 301D. The test compound was incubated at a concentration of 3.2 mg/L over a period of 28 days. Additionally, a refercen substance (sodium acetate) an a toxicity control including the test compound and sodium acetate was used. The test compound reached a plateau of degradation on day 11 with 30% degradation, but remained there until the end of the incubation period. The reference material exceeded 60% degradation on day 4, fulfilling the validity criteria. The toxicity control did not indicate an inhibitory effect of aldona. Thus, aldona is not ready biodegradable. The study was conducted under GLP (see Schering report no.A03238)
