12.1 Toxicity
Menthone's production and use in perfumes and flavor compositions may result in its release to the environment through various waste streams. Menthone is found naturally in many essential oils, such as pennyroyal, peppermint and geranium. If released to air, an estimated vapor pressure of 0.28 mm Hg at 25 °C indicates menthone will exist solely as a vapor in the ambient atmosphere. Vapor-phase menthone will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 14 hours. If released to soil, menthone is expected to have high mobility based upon an estimated Koc of 120. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 1.6X10-4 atm-cu m/mole. Menthone is not expected to volatilize from dry soil surfaces based upon its vapor pressure. If released into water, menthone is not expected to adsorb to suspended solids and sediment in the water column based upon the estimated Koc. Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's Law constant. Estimated volatilization half- lives for a model river and model lake are 0.5 and 8 days, respectively. The potential for bioconcentration is considered low based upon an estimated BCF value of 15. Occupational exposure to menthone may occur through inhalation and dermal contact with this compound at
