Additional information

In an OECD test conducted according to guideline 301 A Ciba-Geigy determined a degradation rate based on DOC removal of 0%. Therefore the test substance is considered to be not biodegradable. This result is supported by the lack of oxygen consumption in a BOD5 test (Ciba Geigy, 1990).
