The 96 h LL50 was > 100 mg/L. The LL50 value was greater than the highest loading rate for all category members tested. There was no
difference in toxicity between low and high molecular weight substances observed for this endpoint.
reliable studies are available for this endpoint (Inveresk 2001a,
Inveresk 2001b, Harlan Laboratories, 2014a), conducted using category
members Resin acids and rosin acids, hydrogenated, Me esters, Resin
acids and rosin acids, esters with pentaerythritol and Resin acids and
rosin acids, esters with ethylene glycol. All studies are GLP-compliant
and followed OECD guideline 203, although the method was modified to use
water accommodated fractions (WAF) due to the nature of the test
substances. Analytical verification of the exposure concentrations was
not carried out in either of the Inveresk studies, but was carried out
in the study conducted at Harlan Laboratories with Resin acids and rosin
acids, esters with ethylene glycol. However, in all studies results were
expressed as nominal loading rates.
In all studies
the LL50 was determined to be greater than the highest loading rate
tested (1000 mg/L for the Inveresk studies and 100 mg/L for the Harlan
Laboratories study). Therefore, an LL50 result of >100 mg/L is
considered to cover all category members.
