Research report: The adsorption, desorption, and possible degradation of benzene in two silty clay loam soils and montmorillonite clay saturated with either aluminum or calcium ions were studied. With benzene concentrations in water of 10, 100, and 1000 ppb, it was found that sorption was minimal for the soils and the calcium-saturated clay. Benzene sorption on the aluminum-saturated clay was seven times greater than on the soils and three times greater than on the calcium-laden clay. Once sorbed, benzene tends to resist desorption. The most likely route of benzene loss from soils appears to be volatilization. (6 graphs, 11 references, 4 tables)
