Toxicity to aquatic plants other than algae
Administrative data
- Endpoint:
- toxicity to aquatic plants other than algae
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- according to general accepted guidelines a minimum of 5 plants should be tested per concentration. In this study only 4 plants were used. As the study is well documented the study can be considered as reliable screening test to assess the effects on submerged macrophytes.
