EC number: 813-937-2
CAS number: 111512-60-8
PBT/vPvB criteria and justification
Persistence (P) Assessment: A substance is not considered to be
persistent if it can be demonstrated that it has potential to degrade
(via photolysis, hydrolysis and/or biodegradation)
In a ready biodegradation study no biodegradation was observed. This may
be due to the fact the substance is very volatile and is likely to
rapidly partition to air. It's fate in air is unknown and it is not
possible to determine if the substance persists in the atmosphere or
undergoes abiotic processes such as photolysis or hydrolysis. It is
unlikely to persist in the aquatic environment due to volatilisation.
However, without further information the substance can be considered
Bioaccumulation (B) Assessment: HCFO 1224yd(Z) has a log Kow of 2.4 and
therefore is not considered potentially Bioaccumulative (B).
Toxicity (T) Assessment:
Human Health Hazards Assessment (T)
HCFO 1224yd(Z) does not meet the criteria for classification as
carcinogenic in Category 1A or 1B (assigned hazard phrases: H350 or
H350i), germ cell mutagenic in Category 1A or 1B (assigned hazard
phrase: H340), toxic for reproduction in Category 1A, 1B and/or 2
(assigned hazard phrases: H360, H360F, H360D, H360FD, H360Fd, H360fD,
H361, H361f, H361d or H361fd), specific target organ toxic after
repeated dose in Category 1 or 2 (assigned hazard phrase: H372 or H373),
according to Regulation EC No 1272/2008. Therefore, HCFO 1224yd(Z) does
not meet the criteria to trigger classification as toxic to human health
Environmental Hazards Assessment (T)
The lowest recorded freshwater EC50 for HCFO 1224yd(Z) was for algae
growth rate at >4.87 mg/l. In this study no effects were observed but
due to the difficulty of the test item the maximum measured mean
concentration was 4.87 mg/l. Therefore, HCFO 1224yd(Z) does not meet the
criteria of an EC/LC50 of <0.1 mg/l to trigger classification as toxic
to the environment (T)
Conclusion of PBT/vPvB assessment
Data available for HCFO 1224yd(Z) shows that HCFO 1224yd(Z) may
potentially be classified as P or vP but is not considered B/vB. It is
also not considered toxic to human health or the environment according
to the criteria in the Regulation.
Therefore, HCFO 1224yd(Z) is not classified as PBT or vP/vB.
