Description of key information

Acute toxicity to the commonly used lettuce Lactuca sativa was investigated in a non-GLP non-guideline approach by Reynolds (1982), seed germination and root elongation were measured using an agar plate on which the plant was sowed. After 3 days an EC50 of 2081 mg/kg soil dw was estimated for the endpoint germination related to the nominal concentration.

Key value for chemical safety assessment

Short-term EC50 or LC50 for terrestrial plants:
2 081 mg/kg soil dw
