Destruction of volatile iodocarbons in the oceans can potentially play an important role in determining the predominant chemical forms of iodine emitted to the atmosphere. Here we report chlorination and hydrolysis removal rates for CH₃I, C₂H₅I, 1-C₃H₇I, and 2-C₃H₇I relevant to oceanic conditions. We have used these rates to calculate oceanic lifetimes for each iodocarbon with respect to total chemical destruction, as a function of seawater temperature. The resulting lifetimes are compared to typical iodocarbon oceanic residence times with respect to volatilization to the MBL. The rate of destruction of 2-C₃H₇I is much more rapid than chemical removal of the primary alkyl iodides, potentially explaining previous observations of lower 2-C₃H₇I concentrations in seawater compared to 1-C₃H₇I. Finally, in light of these results, we briefly discuss the potential impact of rising global seawater temperatures on oceanic iodocarbon concentrations.
