Additional information

Readily biodegradable potential of 124 Triazole has been investigated in the frame of an OECD 301 A test (Thiebaud, 1995). Under the test conditions it is concluded that 124 Triazole is not readily biodegradable.

In addition, an OECD Guideline 302B study (inherent biodegradability: Modified Zahn-Wellens Test) was performed. The test substance showed only a very low degree of degradation (1%) after 28 days (US EPA, 2009).
