- Executive summary:
Myralene was tested via OECD 301F. Sodium acetate was also tested as a control. The inoculum used was surface water. 60% ThOD biodegradation was achieved by day 19 and within the requisite 10 day window. After 28 days, 99% ThOD was acheived. Test material was readily biodegradable according to results of OECD 301F study.
