Key value for chemical safety assessment

Koc at 20 °C:
1 236

Additional information

Two publications from Jin et al. (1997) and Dai et al. (2000), quoted in reliability 2 (since conducted following OECD 106) reported a log Koc of 2.56

(calculated from Kf) in natural soil from China (pH=6.35, OC=1.85%) and a log Koc=3.092 in natural sediment from China (pH=6.75, OC=1.57%).

From this last value, Koc can be calculated and its value is 1236.
