Biodegradation in water: screening test
SIKA Hardener LI was assessed in a closed
bottle test over a period of 28 days, according to OECD guideline 301 D
and EU method C.4-E.Under the test conditions biodegradation of SIKA
Hardener LI reached a mean of 63.4 % after 28 days, based on ThODNO3.
However the pass level of 60 % was not reached within a 10-day period.
Therefore, the test item was considered ready biodegradable failing the
10 day window. The corresponding degradation rate was calculated to be
7.70E‑06 d-1or 3.210E‑07 h-1.
