Oil shale is formed in the earth during a long period of time from the rests of plants and animals. Oil shale contains naturally most of the poly-aromatic hydrocarbon compounds. Most of these compounds are potential carcinogens and therefore environmental pollutants. This book deals with these compounds in the oil shale from the major deposits in Jordan, where also the cancer risk assessment was done.

The present work deals with the development and validated simple HPLC/UV/FLD analytical procedure which enable the measurement of some of the most consumed pharmaceuticals in Jordan (Caffeine, Methotrexate, Diclofenac, Glimepiride, Ibuprofen) at concentration level of g/L. Separation was on RP-C8 column with 1 ml/min flow rate of 1:1 H2O, acetonitrile with 0.1% trifluoroacetic acid, extraction on C18 cartridges of 200 ml sample volume. Correlation coefficients of the pharmaceuticals calibration were higher than 0.997 using UV detector and 0.996 using FLD detector. Recoveries were ranged...
