Polyurethane foam plugs can be successfully used for concentration of trace quantities of benzo(a)pyrene and other PAH from water. The recovery is more or less independent of water flow rates but depends to a great extent on the temperature of the water. For efficient removal, the water temperature should be > 60/sup 0/C. Under these conditions a single foam plug placed in a 25 mm column can effectively retain PAH from up to 5 liters of tap water. For larger volumes, the number of plugs in the column must be proportionately increased.
