Description of key information
The 24-hour LD50 for silkworms is 8900 ppm NaCl when injected into the hemolymph of the larvae.
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil dwelling arthropods:
- 8 900 mg/kg soil dw
Additional information
One toxicity to terrestrial arthropods study was examined for this endpoint. This study was rated as a Klimish score of 2, since it was not a GLP, guideline study, but appeared to follow good scientific practices. In this study 5th instar silkworm larvae (Bombyx mori) were exposed to various concentrations of sodium chloride via injection into the hemolymph. Following 24 hours, the LD50 was determined to be 8900 ppm NaCl for silkworm larvae.
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.
