EC number: 949-859-1
CAS number: -
on the results of a ready biodegradability study with the substance, a
NOEC of 20 mg/L is established for the toxicity to STP microorganisms.
accordance with ECHA guidance (Chapter R.7b: Endpoint specific guidance,
Version 4.0, 2017), absence of microbial toxicity can often be inferred
from biodegradation studies. Therefore, if the substance does not
inhibit the degradation of a procedural control at a certain
concentration, this concentration can be used as a NOEC value. Based on
a ready biodegradability study with the substance, a NOEC of 20 mg/L can
be established, since at this concentration it was determined that the
substance does not inhibit microbial activity. Moreover, the substance
was determined to be readily biodegradable in this study, also
demonstrating that the substance should not be considered toxic to STP
microorganisms at the used concentration.
