“…The obtained results were higher than those detected by Abdallah and Morsy (2013) who found a-BHC in catfish and tilapia fish collected from El-Manzala Lake with range of 0.27 ng/g and 0.17-37.15 ng/g respectively while it was lower than the result obtained by Salah El-Dien and Mahmoud (2011) who revealed that concentration of a-BHC was 24.26 ppb in catfish collected from Sharkia market. The obtained results were similar to the results recorded by Abdallah and EL-Greisy (2006) who study the a-BHC concentration in male and female Tilapia zillii in El-Manzala Lake (1.8 and 2.2ppb) and El-57 Mekkawi et al(2009) where mean value of a-BHC varied from 8.5-15.3 ng/g in three fish farms in Sharkia Governorate, Egypt.…”

Fifteen organochlorine pesticides (OCP) residues were determined in Nile tilapia (Oreochromis niloticus), African catfish (Clarias gariepinus) and Long fin catfish (Chrysichthys auratus) in Qena city, Egypt by gas mass chromatography. Nile tilapia fish significantly (P < 0.05) had the highest concentrations of Dichlorodiphenyldichloroethylene (DDE), endrin, methoxychlor, Dichlorodiphenyldichloroethane (DDD) and endosulfan sulfate with mean ± SD concentration of 6.27±0.68, 25.02±0.01, 6.98±1.88, 33.35±1.76 and 47.82±12.51 ppb respectively. Long fin catfish significantly had the highest concentrations of D-chlordane, alpha hexachlorobenzene (a-BHC) and aldrin with mean ± SD concentration of 82.27±0.45, 11.89±0.56, 11.73±0.48 ppb respectively. Finally, African catfish significantly had the highest concentration of dieldrin with mean concentration 3.53±0.03 ppb and had significant lowest concentration of endrin 1.99±1.39 ppb. OCP residues in all examined raw fish samples were below the maximum permissible limits (MPL) set by Food and Drug Administration. The effect of pan frying on OCP residues showed that the highest reduction rate in OCP in Nile tilapia was 100% for dieldrin and endosulfan sulfate while reduction rate in African catfish was 100% for dieldrin, methoxychlor and endosulfan sulfate. On the other hand, the reduction rate in Long fin catfish was 100% for dieldrin, endrin, methoxychlor, heptachlor epoxide and endosulfan sulfate. The lowest reduction rate was detected in DDD, DDE, b-BHC, heptachlor and DDT respectively. Consumption of studied fish had no potential hazard to human health as hazard ratio was below one. Carcinogenic risk (CR) value considered acceptable risk for b-BHC and considered level of concern for heptachlor epoxide, total DDTs, lindane and total heptachlor.

“…Drain inflows are also responsible for the elevated concentrations of heavy metals (Siegel et al, 1994;Siegel, 1995), organochlorine pesticides (OCs) and polychlorinated bipheny (PCBs) (Yamashita et al, 2000;Abbassy et al, 2003;Abdallah & El-Greisy, 2006) which have been identified in water, sediment and biota. Malformations and discoloration are common within fish from the lake and these are chemically and microbially contaminated (Tennessee Valley Authority, 1997) with elevated levels of OCs and PCBs within fish tissue (Abbassy et al, 2003;Abdallah & El-Greisy, 2006).…”
