Biodegradation in water: screening tests
The test item is considered to be readily
Biodegradation in water and sediment:
The study does not need to be conducted as
the test item is highly insoluble in water, hydrolytically unstable and
Biodegradation in soil
test with the test substance Sika Hardener LH was performed in
accordance with "Method for Testing the Biodegradability of Chemical
Substances by Microorganisms" stipulated in the "Testing Methods for New
Chemical Substances" (Ministry of Health, Labour and Welfare, Ministry
of Economy, Trade and Industry, Ministry of the Environment, Japan).
Under the test conditions of the biodegradation study, the test
substance Sika Hardener LH was completely hydrolyzed to
2,2-dimethyl-3-oxopropyl dodecanoate and hexamethylenediamine. These
converted products were biodegraded. The percentage (average) of
biodegradation by BOD was 91 % after 28 days. Further, the test
substance is considered to be readily biodegradable.
