The objective of this study is to understand the readily
biodegradability of the ESA in the aquatic environment.
Section 3.1, biodegradation test method of the Testing Guidelines for
Toxicology Studies and in compliance with TCCA-Good Laboratory Practice
Standards and Test Guidelines” (Notification No. 2010-29, issued by the
National Institute of Environmental Research, Korea on August 16, 2010).
OECD, 1992.7.17, OECD Guidelines for Testing of Chemicals, TG No. 301C,
MODIFIED MITI TEST (I) “Ready Biodegradability”. .
The percentage biodegradation of the ESA observed by BOD meter was 36.0%
after 28 days.
Therefore, the ESA could not be concluded as readily degradable by
microorganisms in the aquatic environment based on the OECD pass level
of biodegradability (60%).
The substance was tested according to OECD 301C, and after 28 days 36%
degradation was reported by BOD meter. The test item could not be
detected by GC in the abiotic control or treatments and therefore
biodegradation could not be determined by this method. As only 36%
degradation was reported by BOD, the substance cannot be identified as
readily biodegradable according to this test.
