ABSTRACT

Walker et  al. [1] studied the proles of hydrocarbons in sediments according to the depth of sediment cores collected from Baltimore Harbour in Chesapeake Bay, Maryland. Gas-liquid chromatography was used to detect hydrocarbons present at different depths in the sediment, while low-resolution spectrometry was employed to measure the concentrations of parafns, cycloparafns, and aromatic and polynuclear aromatics. Their data showed that the concentrations of total and saturated hydrocarbons decreased with increased depth. It was noted that hydrocarbons in oilcontaminated sediments should be identied and quantied to determine the fate of these compounds in dredge spills.
