Abstract

; "> A total of 120 fish samples were collected from different water sources in El Fayoum
Governorate, (Bahr El Banat agricultural drainage, different fish farms and Al Rayaan
Lake). and represented by Clarias gariepinus from Bahr El Banat agricultural
drainage, different fish farms (15 each), Mugil cephalus from different fish farms
and Al Rayaan Lake (15 each), Solea solea (30 samples) and Oreochromis niloticus
from Bahr El Banat agricultural drainage, different fish farms and Al Rayaan Lake (10
each). Fourteen organochlorine compounds were analyzed by gas chromatography.
Fish samples from Bahr El Banat revealed the highest mean levels of p,p'-DDD,
endrin, endosulfan, γ-chlordane, heptachlor and γ-HCH, while fish samples from Al
Rayaan Lake have shown the highest mean level of methoxychlor, p,p'-DDT, p,p'-
DDE, dieldrin, heptachlor epoxide, δ-HCH and α-HCH. Most of the examined fish
samples from different species, are within the maximum residue limits and should
not pose a health risk to consumers. The public health hazards were discussed as
well as recommendations were done.
