Organics in the water colümn and air-water interface samples of Mississippi river water

Organic compounds in Mississippi river water were collected using a teflon disc to obtain surface film samples and a submerged bottle to collect water column samples. These organics were analyzed and characterized by high resolution gas chromatography-mass spectrometry. The presence of n-alkanes, polynuclear aromatics and chlorinated hydrocarbons was established, with the more hydrophobic compounds found in greater quantities at the air-water interface as compared to the sub-surface water column.
