Measured BCF values for resin acids range from <25 to 130 for fish, and 110 to 330 L/kg for mussels.
are available with measured BCF values for fish and mussels, for various
resin acids. Resin acids are the predominant components of rosin and
rosin salt substances. Therefore, it is considered appropriate to read
across from resin acids to members of the category Rosin, Hydrogenated
rosin and their salts.
trout (Oncorhynchus mykiss) were exposed to nine resin acids that
included abietic, dehydroabietic, chlorodehydroabietic,
dichlorodehydroabietic, neoabietic, pimaric, isopimaric,
sandaracopimaric, and palustric acids (Niimi and Lee 1992).
Bioconcentration factors (BCFs) for these acids ranged from <25 to 130
among fish that were exposed to mean waterborne concentrations of 0.7 to
3.6µg/L for 20 days. Total free and conjugated acid concentrations
ranged from 1 to 3 mg/kg on a whole body basis. Elimination rates were
also monitored over a 10-day depuration period, although no detectable
levels were observed. Based on initial chemical concentrations, it was
concluded that the half-lives of these acids were < 4 days.
et al. (1996) determined BCF values for mussels (Hyridella menziesi)
exposed to effluent from a pulp and paper mill. Concentrations of resin
acids (pimaric acid, isopimaric acid, dehydroabietic acid, abietic acid
and 14 -chlorodehydroabietic acid) were analysed in mussels and in the
effluent for a 28d exposure phase, followed by a 21d depuration phase.
BCF values for the individual resin acids ranged from 110 to 330 L/kg.
was also estimated for some category members using QSAR estimation
software (EPISUITE BCFBAF v3.00), and for rosin, dimer constituents
using EPISUITE BCFBAF v3.01 in accordance with REACH Annex XI. The
calculated BCF values ranged from 3.162 to 56.23 L/kg ww. Calculated BAF
values ranged from 1.474 to 694000.
