Based on the partition coefficient values reported in the literature which ranges from 0.84 to 1.03, Catechol has a low potential for bioaccumulation.
As no reliable data is available on the
bioaccumulation potential of catechol, the assessment has to be
performed based on data on n-octanol/water partition coefficient. Among
the available results, one experimental study, divided in two
publications (Garst & Wilson 1984, Garst 1984), was selected as a key
study and give coefficient partition values ranging from 0.88 to 0.95.
Other experimental and calculated results were selected as supporting
studies, giving values comprised between 0.84 and 1.03. An average of
all the Klimisch 2 data was calculated to obtain the key value of 0.93
used for chemical safety assessment.
on all the above mentioned data, catechol has a low potential for
