Table 2: Biodegradability of test material
ThOD of test material: 2.25 mg O2/mg
B = (B1 + B2)/2
D1 = 100 * (C1 - B)/ThOD*[S]
D2 = 100 * (C2 - B)/ThOD*[S]
D = (D + D2)/2
[S] = initial test material concentration (mg/L)
In a GLP-compliant ready biodegradation study conducted in line with
OECD 301F, the biodegradation of hexenyl-3-cis salicylate was determined
using the Manometric Respirometry Test. The biodegradation of the
substance was determined to be 89% after 28 days. Biodegradation started
on day 2 and reached 82% at the end of the 10-day window. The substance
is considered to be readily biodegradable.
Biodegradation was determined to be 82% biodegradation within 10 days,
89% biodegradation within 28 days; study conducted in accordance with
OECD 301F; Rudio (1995b)
In a GLP-compliant ready biodegradation study conducted in line with a
standardised guideline, the biodegradation of (z)-3-hexenyl
salicylate was determined using the Manometric Respirometry Test.
The biodegradation of the substance was determined to be 89% after 28
days. Biodegradation started on day 2 and reached 82% at the end of the
10-day window. The substance is considered to be readily biodegradable.
As the study was performed to GLP and standardised guidelines, it was
allocated a reliability score of 1 and considered to be the key study.
Supporting information includes two studies performed to standardised
guidelines. One study performed to GLP concluded that hexenyl-3-cis
salicylate appears to be readily biodegradable but that this could not
be determined. Limitations on the methodology meant that this study was
allocated a reliability score of 3. The other study, a concluded that (z)-3-hexenyl
salicylate was readily biodegradable. This study was allocated a
reliability score of 2 due to the limited detail in the reporting of the
methods and results.
