The Biological Oxygen Demand (BOD5) of FAT 36091/E was determined according to in house Ciba Geigy Method A.15, which is comparable to internationally accepted guidelines. Based on these investigations, the BOD5 of test substance was found to be 0 mg O2/g. Considering the COD value determined with the test substance which is 1455 mg O2/g, the resulting BOD5/COD quotient is 0, indicating that the test substance is unlikely to be biodegradable.

Description of key information
An Inherent biodegradability assessment was conducted to measure the biodegradability of the test item. In principle the methods described in OECD Guideline 302B were used (key study on batch E). The testing conditions represents a static method to test substances/products for degradation in activated sludge. Analysis is based on the Total Organic Carbon (TOC). The biodegradation of FAT 36091/E was found to be:
* 18.6 % after 3 hours of exposure time.
* 60 % TOC after 28 days exposure time.
In a second Inherent biodegradability assessment done to measure the biodegradability of the test item by following a method similar to OECD 302B showed 42 % DOC after 37 days. FAT 36091/E is considered to be inherently biodegradable after 28 days (60 % TOC after 28 days). Severals studies, (supporting studies), measuring BOD5 were performed on all batches and BOD5 was found to be 0 mg /g O2 in all experiment excepted for one batch (A) were BOD5 was measured to be 32 mg/g O2 . Since the BOD5 was measured to be zero, no ready biodegradation is expected to take place.
Several other supporting studies reported the following results:
COD (batch A): 1218.48 mg COD/g
COD (batch B): 1328.84mg COD/g.
COD (batch D): 1232.3 mg COD/g.
COD (batch E): 1455 mg/g COD.
COD (batch F): 1124 mg O2/g.
The above studies reported values greater than1000 mg/g for COD and BOD5 value as 0. Relevant is the BOD5/COD quotient which is “zero”, therefore biodegradation is not expected.Taking into consideration the data from two key studies, the test substance FAT 36091 is considered to be not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable
