An Investigation of the Presence of N,N'-Bis(2,4,6-Trichlorophenyl)urea in Estuarine Sediments of Aberdeen Proving Ground, Maryland (Edgewood Area).
Abstract
N,N' -Bis(2,4,6-trichlorophenyl)urea is present in the sediments of Canal Creek in the Edgewood area of Aberdeen Proving Ground, MD. The highest concentrations are found in the top 2 inches of sediment, (100-300 micrograms/g), and the concentration declines with increasing depth. Below a 6-inch depth there is little of no contamination. Although the detection limit of the HPLC method descrived here is 5 micrograms of dry sediment, modification of this method to lower levels is possible. The chemical literature gives little information concerning this material, but does indicate a very high stability to chemical hydrolysis. The solubility in water is quite low (82 microgram at 22 degrees) and the estimted octanol/water partition coefficient is high (log K >5). The conjunction of these properties points to long persistence of the compound in the environment.
