- Conclusions:
- Under the conditions used TPP did not adversely affect the micro-organisms present
- Executive summary:
The test was conducted in accordance to "301C, Ready Biodegradability: Modified MITI Test (I)" stipulated in the OECD Guidelines for Testing of Chemicals (1981).
TPP (100 mg/L) was incubated for 28 days at 25 °C with activated sludge (30 mg/L as concentration of suspended solid) in a volume of 300 mL. Degradation was determined by BOD. Under the conditions used TPP did not adversely affect the micro-organisms present, since the biodegradability of TPP showed a result of 83 - 94 %.
Reference
Since the biodegradability of TPP showed a result of 83 - 94 % after 28 d of incubation with 30 mg/L sludge and 100 mg/L TPP in a test on ready biodegradability, there is no significant effect of TPP in the low concentration range expected.
Description of key information
TPP (100 mg/L) was incubated for 28 days at 25 °C with activated sludge (30 mg/L as concentration of suspended solid) in a volume of 300 mL. Degradation was determined by BOD. Under the conditions used TPP did not adversely affect the microorganisms present, since the biodegradability of TPP showed a result of 83 - 94 %.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 100 mg/L
Additional information
The key values should be understood as > 100 mg/L as no effect was observed up to the highest test concentration of 100 mg/L.
