Executive summary:

Hulzebos et al. (1993).

EC50 values for growth of lettuce (Latuca sativa) exposed to chlorobenzene were determind to be 1000 mg/kg soil in a 7-day test and >1000mg/kg soil in a 14 -day test. This test was carried out according to OECD Testguideline 208. In addition a nutrient solution test was performed and EC50 value of 9.3mg/L was measured.
