4.3 TOXICITY TO AQUATIC PLANTS E.G. ALGAE
Species : Selenastrum capricornutum (Algae)
Endpoint : other: chlorophyll a
Exposure period : 96 hour(s)
Unit : mg/l
NOEC : ca. .2 calculated
EC10 : ca. .2 calculated
EC50 : = .6 calculated
EC7 : = .1 measured/nominal
EC13 : = .3 measured/nominal
Limit test :
Analytical monitoring : No
Method : other: Algal Assay Procedure: Bottle Test (US-EPA 1971)

Result : Calculated EC50. Criterion for effect was decrease of in vivo chlorophyll a
in exposed cultures as compared to control at 24, 48, 72 and 96 h or
decrease of cell numbers in exposed cultures as compared to control at 96
h.
