study was performed to assess the effect of the test material on the
growth of the green alga Scenedesmus subspicatus. The
method followed that described in the OECD Guidelines for Testing of
Chemicals (1984) No. 201, “Alga Growth Inhibition Test”.
Following a preliminary range finding test,
the alga were exposed to Water Accommodated Fractions of test material
over a range of nominal loading rates of 10, 20, 40, 80, and 160 mg/L
(three replicate flasks per concentration) for 72 hours, under constant
illumination and shaking at a temperature of 24 degrees C. Samples
of the algal populations were removed daily and cell concentrations
determined for each control and treatment group using a Coulter
Multisizer Particle Counter.
