Abstract
Concentrations of polycyclic aromatic hydrpcarvons (PAHs) in some seafoods caught from Lake Timsah were determined. The tested samples were tilapia fish ( Oreochromis aureus ), crabs ( Portuns pelagicus ), bivalves ( Venerupis decussata ), clams ( Strombus tricornis ) and gastropods ( Munes Sp. ). Where these seafoods are locally and favorite consumed foods in the area around the lake (Ismailia governorate). Results showed that crabs contained significantly higher concentrations of both total and carcinogenic PAHs ranging from 1318.6 to 3767.4 and 1230.3 to 3442.2 w g kg -1 , respectively. Meanwhile, clams contained significantly lower levels with mean value of 28.4 w g kg -1 for total and 24.4 w g kg -1 for carcinogenic PAHs. The most frequently detected PAHs in the tested samples were indeno(1,2,3-cd)pyrene followed by benzo(a)pyrene, dibenzo(a,h)anthracene, and benzo(b)fluoranthene which are characterized as carcinogenic compounds.
