experimental study
Adequacy of study:
supporting study
Study period:
2016
Reliability:
3 (not reliable)
Rationale for reliability incl. deficiencies:
significant methodological deficiencies
Justification for type of information:
Guideline study. No information on GLP. No analytical verification of the used dose.
Guideline:
OECD Guideline 221 (Lemna sp. Growth Inhibition Test)
GLP compliance:
not specified
Specific details on test material used for the study:
Manufacturer: F&N dodavatelé Ltd., Tišice, Czech Republic
Analytical monitoring:
no
Details on test solutions:
The concentration of saccharin was 0 mg/l (control) and 100 mg/l.
Test organisms (species):
Lemna minor
Details on test organisms:
Lemna minor was to be delivered by the Federal Environmental Agency, Berlin, Germany.
Test type:

Key result
Duration:
1 d
Dose descriptor:
other: No. of fronds (day–1)
Remarks:
No. of fronds (day–1) was 0.21 ± 0.12 and frond area (day–1) 0.18 ± 0.

Duration:
1 d
Dose descriptor:
other: chlorophyll (μg/cm2)
Effect conc.:
100 mg/L
Nominal / measured:
nominal
Conc. based on:
test mat.
Basis for effect:
other: chlorophyll (μg/cm2)
Details on results:
No statistically significant adverse effect upon short-term exposure was identified but saccharin caused a negative effect
after prolonged exposure (Lemna minor).
Conclusions:
Saccharin had no negative effects on duckweed (Lemna minor) at the concentration of 100 mg/L during one day of exposition.
Executive summary:

OECD 221 test was performed with saccharin. It had no negative effects on duckweed (Lemna minor) at  the concentration of 100 mg/L during one day of exposition.
