Description of key information

Key value for chemical safety assessment

BCF (terrestrial species):
1 200 000 L/kg ww

Additional information

There are no data on terrestrial bioaccumulation for M3T. In order to facilitate assessment of secondary poisoning via the terrestrial food chain, a predicted BCF is required. Although the predicted log Kow of M3T (8.2) is outside the boundaries of EUSES model for bioaccumulation,a EUSES predicted bioconcentration factor for earthworm of 1.2E+06 l/kg wwt (based on a maximum acceptable log Kow of 8) is considered to be a reasonable approximation and has been used for the assessment. To enable assessment within CHESAR, this value is entered in the Key value field.
