Description of key information

The lowest NOEC of the key study determined in the tests was 17 mg/kg dry weight for emergence of L. sativa seedlings.

Key value for chemical safety assessment

Long-term EC10, LC10 or NOEC for terrestrial plants:
17 mg/kg soil dw

Additional information

A report has been submitted describing the results of emergence and growth tests with the plant specie sTriticum aestivum (Wheat), Sinapis alba (Mustard), Lactuca sativa (Lettuce) (Servajean, E. 2003b). The tests fulfilled the criteria for acceptability for determining a PNEC. The lowest NOEC determined in the tests was 17 mg/kg dry weight for emergence of L. sativa seedlings. The lowest NOECs determined for S. alba and L. sativa were 28 and 18 mg/kg respectively based on 21-day post emergence plant wet weight. In this case, correction for organic matter content in the test (1.4%) would give a more favorable result and therefore this correction has not been made.

NOEC = 17 mg/kg dry weight
