The purpose of this study was to determine the effects of SLI (76)
stripped on survival and reproduction of Daphnia magna.
SLI (76), provided by Unilever Mannheim was stripped of its fatty acid
content via Soxhlet extraction at the Materials Science Laboratory,
Trumbull, USA. The resulting material, SLI (76) stripped was used for
Daphnia were exposed to a range of concentrations, nominally 0.0, 560,
1000, 1800, 3200 and 5600 μg/L. Test item analysis was performed to
determine total and dissolved concentrations. The dilution medium used
was Elendt M7 artificial medium. A 3.4 x 105 cells/mL aliquot of Chlorella
vulgaris and 1.4 mL of a 1 g/L Microfeast PZ20 supplement was added to
the test media containing the appropriate concentration of SLI(76)
stripped. The stock solution and test media were renewed daily.
The data were analysed using an analysis of variance followed by
Dunnett’s test to obtain the
21 day NOEC for mean juvenile production, time to release of first brood
and size of first
The lowest value determined for an adverse effect was time to first
brood. The 21 day NOEC for this endpoint based on dissolved
concentrations was 154 μg/L (192 μg/L total concentration).
There was no statistically significant effect at any concentration on
size of first brood therefore the NOEC for this endpoint based on
dissolved concentrations can be quoted as >717 μg/L (>1307 μg/L total
A statistically significant stimulatory effect was observed at all
concentrations based on number of neonates per surviving adult. The
number of neonates rose steadily up to a dissolved concentration of 260
ug/L (289 μg/L total concentration) after which it then began
to decline. The NOEC for this endpoint cannot therefore be determined
with any confidence. The 21 day NOEC for adult mortality is 260 μg/L
based on mean measured dissolved concentrations (289 μg/L as total
