Environmental fate: Animals:For a study of the metabolism of cinmethylin in the goat, see J. Agric. Food Chem., 1989, 37, 787.Soil:Strongly adsorbed by soils (B. T. Grayson et al., Pestic. Sci., 1987, 21, 143), but relatively short-lived in the environment, being broken down in the soil under aerobic conditions. WATER SOLUBILITY: 63 ppm.
