The soil sorption coefficient Koc of citral was calculated using EPIWIN v3.12, PCKOCWIN v1.66. The calculation yielded a Koc=147.7. Taking into account the classification of Blume & Ahlsdorf (1993), a low sorption of citral onto soil organic matter is to be expected.

Henry's Law constant

Henry's Law constant of citral was calculated using EPIWIN v3.12, HENRYWIN v3.10. The calculation yielded values of 3.76 x 10E-4 atm x m³/mole (38.1 Pa x m³/mole) and 4.35 x 10E-5 atm x m³/mole (4.41 Pa x m³/mole; at 25°C each) using the bond and group method, respectively. The calculation of Henry's Law constant according to the equation H=vp/ws and using EPIWIN estimates for water solubility and vapour pressure resulted in a Henry's Law constant of 2.16 x 10E-4 atm x m³/mole (21.9 Pa x m³/mole; at 25°C). The results point on a moderate to high volatility of citral from aqueous solution.
