EC number: 229-066-0
CAS number: 6408-72-6
Any decomposition of the substance
in water is not considered by the program.
Defined endpoint: bioconcentration of a substance in biota
Unambiguous algorithm: linear regression QSAR. Because of the
deviation from rectilinearity, different models were developed for
different log Kow ranges. Metals (tin and mercury), long chain alkyls
and aromatic azo compounds are specially treated.
Applicability domain: the model is applicable to ionic as well as
non-ionic compounds. It is applicable to substances with a logKow in the
following range: -6.50 to 7.86 (ionic compounds) and -1.37 to 11.26
(non-ionic compounds). Applicable to substances with a molecular weight
in the following range: 102.13 to 991.80 g/mole (ionic substances) and
68.08 and 959.17 g/mole (non-ionic compounds). ). Model predictions may
be highly uncertain for chemicals that have estimated logKow values > 9.
The model is not recommended at this time for chemicals that appreciably
ionize, for pigments and dyes, or for perfluorinated substances.

Mechanistic interpretation: The BCF is an inherent property used
to describe the accumulation of a substance dissolved in water by an
aquatic organism based on the lipophilicity of the compound.
Solvent violet 59 falls within the applicability domain described above
and, therefore, the predicted value can be considered reliable taking
into account that the standard deviation error of prediction of the
external test set is 0.59 (logBCF). Considering that error, the
predicted value is not above or close to the criterion to consider a
substance as potential bioaccumulative.
The bioaccumulation factor (BCF)
of Solvent violet 59 was estimated to be 379 L/kg wet-wt sing the BCFBAF
model included in the EPI-Suite Programm concluding that the substance
has a low potential to bioaccumulate in biota. Within the scope of the
Persistency-Bioaccumulation-Toxicity (PBT)-Assessment, the substance
does not fullfil the B-criterion. Solvent violet 59 falls within the
applicability domain described above and, therefore, the predicted value
can be considered reliable.
The bioaccumulation factor (BCF)
of Solvent violet 59 was estimated to be 379 L/kg wet-wt using the
BCFBAF model included in the EPI-Suite Programm concluding that the
substance has a low potential to bioaccumulate in biota.
