✦ Synopsis
An attempt was made to see if simple liquid-solid chromatography with a UV absorption detector could be used to monitor non-point source petroleum pollution in organisms instead of gas-liquid chromatography (GLC), Petroleum derived material in nine algal communities and in 10 invertebrate populations on the rocky shores of Bermuda was analyzed by both methods.
No significant linear or logarithmic relationship was found between the results obtained by the two different methods. Therefore it was decided that UV absorption measurements could not be used for monitoring non-point source petroleum pollution.
There was a very significant correlation (r=0.99) between the area of the unresolved envelope of the chromatograms and the total amount of petrogenic hydrocarbons (PHC) found by GLC. This relationship was found to be valid in the range of 2.5 ~tg to 315 ~tg PHC per g of tissue (wet weight). Therefore in a monitoring program it should be sufficient to measure the unresolved envelope alone without the need of determining the total PHC content.
