perylene and penta-aromatic hydrocarbons were determined in sediments as part of a study that was dedicated to the aquatic ecosystem of oginigba creek (southern nigeria) in order to carry out a critical corroboration of occurrence and diagenetic evolution of perylene in the sediments of the creek. the results show that the annual mean levels of perylene ranged from 396.27– 507.19 mg/g dry wei...
