PBT and vPvB assessment
According to Annex XIII of the REACH Regulation (EC) No 1907/2006, a PBT
substance has to fulfill all three of the criteria for persistence,
bioaccumulation and toxicity, as listed in part 1 of Annex XIII, and a
vPvB substance has to fulfill all criteria for persistence and
bioaccumulation, as listed in part 2 of Annex XIII.
The principal fate of chloroform is temperature-dependent
volatilization, due to its volatile nature. Chloroform emitted to air
reacts primarily with photochemically generated hydroxyl radicals in the
troposphere. (1H)Chloroform and (2H)Chloroform that partitions to the
atmosphere has a mean half-life of 70 days. Wet deposition is
considered minor, as most will return to the air by
volatilisation. Therefore, (1H)Chloroform and (2H)Chloroform are not
considered to be persistent even if chemical degradation is not rapid,
except under anaerobic methanogenic conditions. The principal removal
process from water or soil is volatilization.
About 90% of chloroform in the environment is naturally produced.
Chloroform ((1H)Chloroform and (2H)Chloroform ) does not accumulate in
the environment as the low Log Kow indicates that the substances are
unlikely to bioaccumulate to any significant extent in aquatic biota.
Chloroform ((1H)Chloroform and (2H)Chloroform ) fulfils the toxic (T)
criterion being toxic for reproduction and after repeated exposure.
Therefore, chloroform is not a PBT / vPvB.
(2H)Chloroform is not identified as PBT or as a vPvB substances on the
basis of the relevant data provided and discussed.
