ABSTRACT
Iodoform can be released to the environment through its application as an antiseptic although present use is rather limited. If released to water, iodoform may evaporate into the atmosphere with a volatilization half-life of approximately 3.08 days from a model river. In water, some iodoform may also partition to sediment. Vapor-phase iodoform is degraded slowly in the ambient atmosphere by reaction with photochemically formed hydroxyl radicals; the half-life for this reaction in typical air can be estimated to be about 325 days. Based on the reported water solubility, the BCF for iodoform can be estimated to be 44.5 using a recommended regression-derived equation. Based on the reported water solubility, a soil adsorption coefficient (Koc) for iodoform of approximately 336 was estimated using a linear regression derived equation. This Koc value indicates that iodoform would probably be moderately mobile in soil and that slight adsorption to suspended solids and sediments in water may take place.
