Table 2.
Toxicity-Kd values describing the sorption of imidacloprid in LUFA 2.2 soil estimated from the LMC50s for lethal and moribund effects on Folsomia candida exposed for 14 and 33 days in soil, in water, and in pore water extracted from the LUFA 2.2 soil
| Time (d) | Soil LMC50 (mg/kg soil) | Water LMC50 (mg/L) | Porewater LMC50 (mg/kg soil) | Predicted Porewater LMC50 (mg/L) | Toxicity-Kd (L/kg) |
|---|---|---|---|---|---|
| 14 | 0.28 (8.26) | 9.99 (24.4) | 1.79 (5.55) | 9.53 (53.8) | 0.03 |
| 33 | 0.16 (0.31) | 3.04 (6.22) | 1.20 (1.38) | 2.59 (4.71) | 0.05 |
LC50s are in parentheses. Predicted porewater LMC50s and LC50s were estimated from a correlation of water and extracted porewater toxicity values; see Fig. 1
