CAS number: 65996-79-4
The distillate from either high temperature coal tar, coke oven light oil, or coal tar oil alkaline extract residue having an approximate distillation range of 130°C to 210°C (266°F to 410°F) Composed primarily of indene and other polycyclic ring systems containing a single aromatic ring. May contain phenolic compounds and aromatic nitrogen bases.
Toxicity to aquatic algae data are available
for 5 streams within this Category. On the basis of loading rates, the
72 hour ErL10 ranged 1.3 -1.7 mg/L (WAF) and the ErL50 ranged from 1.6 to
The 96 hour ErL50 ranged 1.4 - 1.5 mg/L
(WAF). On the basis of measured concentrations, the 72 hour NOEC ranged
0.30-0.37 mg/L and the 96 hour NOEC ranged 0.30 - 0.94 mg/L.
CAS No 68478-10-4 (ACC,
2004g): This is a GLP compliant guideline study considered adequate for
assessment. The effects on growth rate (r) based upon actual loading
rates for Dicyclopentadiene/Codimer Concentrate (DCPD/Codimer
Concentrate) give a 72 hour ErL50 of 1.3 mg/L
(WAF), a 96 hour ErL50 of 1.4 mg/L (WAF) and 72
and 96 hour NOELR of 0.47 mg/L (WAF). On the basis of measured
concentrations, the 72 and 96 hour NOEC is 0.30 mg/L.
CAS No 68477-54-3 (ACC,
2004h): This is a GLP compliant, guideline study considered
adequate for assessment. The effects on growth rate (r) based upon
actual loading rates for Low Dicyclopentadiene Resin Oil (Low DCPD Resin
Oil) gave a 72 and 96 hour ErL50 of 1.5 mg/L
(WAF), a 72 hour NOELR of 0.46 mg/L (WAF) and a 96 hour NOELR of 1.1
mg/L (WAF). On the basis of measured concentrations, the 72 hour NOEC is
0.37 mg/L and the 96 hour NOEC is 0.94 mg/L.
authors report results based on nominal loading rates (WAF) and mean
measured concentrations. As the test substance is a hydrocarbon stream
with various components reporting a measured concentration could be
misleading as the measured concentration does not relate to a
concentration of the raw stream. Instead, we have used the results
reported as WAF, which better represent the potential toxicity of the
