استخلاص وتقدیر الهیدروكربونات الأروماتیة المتعددة الحلقات السامة في عضلات الاسماك المحلیة

Abstract

In this study polycyclic aromatic hydrocarbons were extracted from themuscles of six local fish species (Otolithes ruber, Saurida tumbil, Pseudorhombusmalayanus, Acanthopagrus latus, Hypophthalmichthys molitnx and Tenualosailisha) and analyzed by gas chromatography provided with Flame IonizationDetector (FID). After that compounds were identified and their concentrations werecalculated. The PAHs compounds included naphthalene, indole, 2-methylnaphthalene,1- methylnaphthalene, biphenyl, acenaphthylene, acanaphthene,dibenzofuran + fluorine , anthracene + phenanthre , fluoranthene, carbazol, pyrene,benz (a) anthracene, chrysene, benzo (b) fluoranthene +benzo (k) fluoranthene,benzo(a) pyrene, indeno (1,2,3-cd) pyrene, dibenz (a,h) anthracene and benzo (g,h,i)perylene. Also the results showed that all fish samples contained polycyclicaromatic hydrocarbons in their muscles, the total mean of these compounds rangedfrom 5.191 μg/kg in Tenualosa ilisha to 23.963 μg/gm in Acanthopagrus latus.
