Abstract

Forty-three samples from fifteen locations extending along 200 kilometers from near the Tunisian borders to 20 kilometers east of Tripoli harbour were examined for their organic contents. Sampling was conducted under the following specifications. 1- Dry beach sand, 3-4 meters away from water (denoted ds). 2- Wet beach sand, obtained from 1 meter depth (denoted ws). 3- Beach water (denoted w). Known amounts of sand (ds or ws) and beach water (w) were extracted with a suitable volume of chloroform. Organics in the extracts were determined gravametriclly by complete evaporation of chloroform, the residue was further examined by gas chromatography, and distribution of carbon numbers in each sample were
