Description of key information

TLM QSAR modelling was used to calculate LL50 and NOELR values for isoprene towards terrestrial plants. The calculated LL50 of A. sativa is 147.708 mg/kg soil dw and NOELR is 28.297 mg/kg soil dw. The calculated LL50 of B. rappa is 95.368 mg/kg soil dw and NOELR is 18.27 mg/kg soil dw.

The lowest values were used for chemical safety assessment.

Key value for chemical safety assessment

Short-term EC50 or LC50 for terrestrial plants:
95.368 mg/kg soil dw
Long-term EC10, LC10 or NOEC for terrestrial plants:
18.27 mg/kg soil dw
