Constituent 1
Test organisms
- Species:
- other: other terrestrial plant: orange
Test conditions
- Details on test conditions:
- Orange seedlings, 2 inches in height, were planted in soil which was exposed to 2.5, 25, 250 and 1000 ppm methacrylic acid (three replicates of each concentration, three controls). The soil was immediately watered. The soil had been adjusted to 100 ppm inorganic nitrogen. After growing for about 5 months, the plants were harvested and dried at 60 °C for 2 days. The weights of the tops and roots were then recorded to determine the effects of the various concentrations on growth.
- Nominal and measured concentrations:
- 2.5, 25, 250 and 1000 ppm
Results and discussion
- Details on results:
- A concentration of 1000 ppm Methacrylic acid was lethal toward orange seedlings.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
