EC number: 204-279-1
CAS number: 118-82-1
Due to the fact that the substance did not show adverse effects in
aquatic toxicity studies with acute and chronic exposure up to the
solubility limit, no aquatic PNEC values could be derived. The substance
underwent rapid primary degradation in an activated sludge die-away
test. If released to the environment, the substance is expected to
partition to sediment and soil. Further research is being undertaken on
potential toxic effects to organisms living in these compartments,
degradation pathways and bioaccumulation properties. In the interim, a
PNECsoil has been proposed based on available data from the Environment
Canada chemicals regulation programme.
A PNEC for secondary poisoning could be derived from chronic mammalian
dietary data in two species with similar NOECs. The standard assessment
factor of 30 was applied, but it could be a conservative estimate given
the similarities in response in the two test species (rat and dog). As
the substance is neither classified for environmental nor for human
health endpoints, an exposure assessment is not mandatory according to
the REACH legal text and REACH guidance B.8. Version 2.1, December 2011.
Therefore an exposure and risk assessment is not performed at this point
Due to the absence of acute and chronic toxicity in aquatic organisms at
the solubility limit of the substance in the aquatic environment, a
bioconcentration value (BCF) of > 500 in a fish study, and the
indication of rapid primary degradation in an activated sludge die away
test, the substance is not classified for environmental hazards in
accordance with Regulation 1272/2008 and amendments.
