According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere, urea, which has a vapor pressure of 1.2 x 10 mmHg at 25°C, will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase urea is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals the half-life for this reaction in air is estimated to be 9.6 days.
