A new technique for the solution of references problem in oil pollution measurement by UVF technique

Abstract

In this work, the problems of references used for oil pollution measurement by UVF method were discussed. The main problem of this method is that the origin of the reference for pollutant oil is unknown. The proposed solution for this problem was based on sea water sample which was taken from contaminated area, extracted by DCM, the organic phase was distilled, its calibration curve was plotted with this residue oil and measurement was made on its equation. The oil pollution results for the sea water of K 0 station by using this equation for 2013 was 15.21 mg/L and for 2014 15.25 mg/L. for the same samples determination of oil pollution by using crude oil references varies between 0.11 and 1.15 various crude oils and using chrysene reference 0.11-0.19 mg/L. These results show that pollution level varied depending on references used. The proposed method more realistically determines the oil pollution level. The proposed technique is the first for oil pollution measurement by UVF.
