Description of key information

Adsorption coefficient of 3-Methylpyrazol on soil: log Koc = 1.2 +/- 0.8 (pH = 6.0, 25°C)
Adsorption coefficient of 3-Methylpyrazol on sewage sludge: log Koc = 1.2 +/- 0.8 (pH = 6.0, 25°C)
solids/water coefficient was calculated with EUSES 2.1 = 0.95 m3 x m-3 => log kp solids/water = 0 L/kg for a density of 1
suspended-matter/water coefficient was calculated with EUSES 2.1 = 1.36 m3 x m-3 => log kp suspended-matter/water = 0.13 L/kg for a density of 1
sediment-matter/water coefficient was calculated with EUSES 2.1 = 1.26 m3 x m-3 => log kp suspended-matter/water = 0.1 L/kg for a density of 1
