A static salt sediment long term toxicity test was performed according
to OSPAR Protocols on Methods for the Testing of Chemicals used in The
Offshore Industry, Part A: A Sediment Bioassay using an Amphipod
Corophium sp., Oslo and Paris Commission 2005, with slight modifications.
The test organisms, adult estuarine amphipods (Corophium volutator),
were collected from a wild population. The test water was filtered
natural sea water and the sediment a silty sand sediment collected from
the same location as the test organisms. It was sieved (500 µm mesh) and
homogenized thoroughly prior to the test. The sediment was spiked with
the test material (control and nominal concentrations of 1.2, 3.7, 12,
37, 117, and 1165 mg/kg dry weight) with exposures conducted in
triplicate (10 organisms per test vessel). At the end of the 10-day
test, mortality in each test vessel was determined and the median lethal
concentration (LC50) was defined. The LC50 value was 1200 mg/kg dry
weight (d.w.) with 95% confidence intervals of 800 - 3700 mg/kg d.w. The
reported No Observed Effect Concentration (NOEC) was 373 mg/kg d.w. and
the Lowest Observed Effect Concentration (LOEC) was 1165 mg/kg d.w.
According to The Offshore Chemical Notification Scheme (OCNS), which
classifies chemicals using test protocols approved by the Oslo and Paris
Commissions (OSPAR), NExBTL renewable diesel belongs to a group with the
least environmental hazard potential because the LC50 (Corophium
volutator) falls into the range 1000 – 10 000 ppm and the material is
Results from this investigation along with data supporting ready
biodegrability indicate that NExBTL renewable diesel does not present a
hazard to sediment organisms.
