DBCP in soil can volatilize from near-surface soil. Based on estimated Koc values of 149 in Lincoln fine sand and 128 in an unspecified soil, DBCP will be highly mobile in soil and has the capacity to leach into groundwater. It is estimated that the volatilization half-life for this chemical will vary between 0.6 days in dry soil with low soil organic content and 26.2 days in a wet soil containing high values of soil organic content. It is important to notice that fields treated with DBCP will present a significant retardation in the volatilization loss from the soil if plastic coverings are used.DBCP will exist primarily in the vapor phase in the ambient atmosphere. It is expected that very small amounts of this chemical will be present in the particulate phase, and this could explain the fact that dry deposition to the earth’s surface will not result in a significant removal process. DBCP presents high water solubility, and then small amounts present in the air can be removed by wet deposition.If found in water, DBCP will volatilize quite rapidly to the atmosphere; the estimated volatilization half-life from a pond is 8 days. Using again the estimated Koc values of 128–149, this chemical is not expected to adsorb significantly to sediment and suspended organic matter. Based on an estimated bioconcentration factor (BCF) of 11.2, it is not expected to bioconcentrate in fish and other aquatic organisms. There is no sufficient data to indicate that DBCP could be a potential risk in terms of biomagnifications in different aquatic or terrestrial food chains. However, some biodegradation of DBCP in groundwater might ensue under anaerobic conditions.
