The fraction of tar acid rich in 3- and 4-methylphenol, recovered by distillation of low-temperature coal tar crude tar acids.
As cresol isomers are neither expected to persist in sediment nor to accumulate in sediment-dwelling organisms any toxic effect can be excluded.
No data on toxicity to sediment
organisms are available. In accordance with section 1 of REACH Annex XI,
the study does not need to be conducted as the trigger values for
sediment assessment are not exceeded. According to chapter R.7b of the
RIP guidance documents (ECHA, 2008) trigger values for sediment
assessment are a log Kow or log Koc of ≥ 3, taking into account the
adsorption behaviour to sediment and the bioaccumulation potential of
the test substance. o-Cresol, m-cresol, and p-cresol have low log Koc
values ranging between 1.34 and 1.75, which suggest a low potential of
these isomers to adsorb to soil and sediment. Log Kow values of 1.94 to
1.96 also suggest a low bioaccumulation potential, which is supported by
bioaccumulation factors of 10.7 to 20. As cresol isomers are neither
expected to persist in sediment nor to accumulate in sediment-dwelling
organisms any toxic effect can be excluded and studies on toxicity to
sediment organisms are scientifically unjustified.
