Description of key information

Toxicity to terrestrial plants

The 4 month (growing season) NOEC for exposure of potato plants to ambient ethylene concentrations was <10 ppm (nominal) based on yield and harvest parameters.

The estimated LL50 values from TLM QSAR modelling for this substance were 75.35 and 48.65 mg/kg soil dw and estimated NOELR values were 14.43 and 9.32 mg/kg soil dw toAvena sativaandBrassica rapa, respectively.

Additional information

The terrestrial toxicity to microrganisms ror the purpose of risk assessment, sediment PNECs for the constituent has been derived using aquatic PNECs in conjunction with the equilibrium partitioning method (EqP).
