EC number: 201-052-9
CAS number: 77-73-6
The mean concentration of the test material
which began to inhibit growth of the test organism was 17% WAF. This
corresponds to about 2ppm expressed as Total Organic Carbon, which in
turn corresponds to 2.2 mg DCPD/L. The estimated EL50 value from TLM
QSAR towards activated sludge is 102.533 mg/L.
One study was available for review for
toxicity to microorganisms. This is a WAF, GLP compliant study which
followed a standard method and is considered adequate for assessment
The aquatic toxicity of this substance was
estimated using the Target Lipid Model based on methodologies described
by Mcgrath et al. (2004).The
estimated 72-hr EL50 value for activated sludge is 102.533 mg/L.
