Detection of Organochlorine Pesticides Residues in Nile Fish and Its Risks in Qena City
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...

| Sumario: | 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 |
