Occurrence and possible sources of perylene in marine sediments-a review☆

摘要: Abstract This report presents a review of the occurrence perylene in marine sedimentary environment. Surface sediment samples and cores predating modern anthropogenic pollution from different lacustrine locations also peat various regions world have been analyzed for perylene. New data gathered on current study is compared with earlier research findings to address question its possible origins. Several conclusions could be drawn this compilation. (i) Perylene widespread primarily reducing sediments, commonly found at background level 10 ppb. (ii) As much as 4 ppm has detected some unpolluted anoxic sediments. (iii) originates sediments fed by both terrestrial aquatic organic debris. (iv) Diatoms appear major potential precursors regime. (v) The precise role diatoms adsorption, entrapment or production currently unknown. (vi) Low levels encountered oxic derived inputs.
