Comments on
the Data
Acetone: 0.05 mL The methods
reportedly
followed U.S.
EPA, 1971
guidelines.
Control growth
was not reported.
A NOAEC did not
appear to be
observed because
a 15% decrease in
chlorophyll " and
4% decrease in
cell number was
observed after 96
hours at the lowest
concentration of
0.6 mg/L. Test
substance purity
was not reported.
