CAS number: 90640-86-1
Distillate from the fractional distillation of coal tar of bituminous coal, with boiling range of 240°C to 400°C (464°F to 752°F). Composed primarily of tri- and polynuclear hydrocarbons and heterocyclic compounds.

concentrations were nominal (n)
Due to the
short residence time of phenanthrene in soil, the actual exposure
concentrations were lower, and therefore, the real effect concentration
could be much lower, with an EC50 in the order of 10 -100
mg/kg and a NOEC for reproduction of 4 – 50 mg/kg.
reasonable estimates arrive at a NOEC
(reprod.) of 25 mg/kg and EC50
of 60 mg/kg dw.
