CAS number: 57693-14-8
Three studies according OECD guideline 302
B are available. The biodegradation found in these inherent
biodegradable studies were 13 % respectively 26.8 % in two static tests.
One test was conducted with adapted sludge (adaption 28 days) and showed
a biodegradation of 69 % in 20 days. Although the criteria for
inherently biodegradability are not fulfilled the results shows that the
substance has the potential to biodegrade particularly in an environment
with adapted microorganisms which will be found in the STP of the dye
factories. The ‘P’ criterion according to Annex XIII is fulfilled for
The partition coefficient (octanol /water)
of the test subbstance hase been determined by the shake flas method
(logPow= -1.74) and estimated by the calculation from the solubilities
in water and octanol (logPow= -2.11). The ‘B’ criterion for Acid Black
172 is NOT fulfilled.
The substance is classified as hazardous
to the aquatic environment (long-term) – Aquatic Chronic 2. This
classification results from eleven aquatic toxicity tests. The lowest
value is the 96-hour LC50 of 3 mg/l for freshwater fish. The criteria
for T are not fulfilled. The 'T' criterion for Acid Black 172 based on
the lowest aquatic (acute) toxicity result is NOT fulfilled as the
toxicity value of 3 mg/l is above the toxicity criteria of 0.1 mg/l for
the aquatic compartment.
Overall, for Acid Black 172, ‘P’ criterion
is fulfilled but ‘B’ and ‘T’ criteria are not. Therefore, Acid Black 172
is neither a 'PBT' nor a 'vPvB' substance.
