Study on some heavy metals residues in Nile fish in Qena Governorate
Atif Ahmed Aly Metwally;
Abstract
A total number of 165 fish samples offresh water fish investigated
. in this study were collected from five districts in Qena Governorate all over year. 115 fish samples from Tilapia nilotica 20 from each district except Nag-Hamady which 35 samples, and Clarias lazera 10 fish samples from each five stations "Nag-Hamady, Qena, Kous, Luxor and Esna".
Collected samples were examined organoleptically then analyzed for heavy metals content namely: cadmium, lead, copper and zinc.
Statistical analytical results for cadmium levels of Tilapia nilotica and Clarias lazera (ppm) fish caught from different districts in Qena Governorate revealed that as mean ± standard error. From Nag-Hamady were 0.339±0.025 and 0.450±0.090, respectively. From Qena were
. 0.319±0.052 and 0.366±0.059, respectively. In Kous were 0.417±0.034 and 0.406±0.070, respectively. In Luxor were 0.394±0.030 and
0.337±0.053, respectively. In Esna were 0.342±0.030 and 0.264±0.046,
respectively.
The statistical analytical results of lead levels in T. nilotica and C. lazera fish (ppm) caught from different districts in Qena Governorate were expressed as mean ± standard error. From Nag-Hamady were
0.530±0.085 and 0.259±0.048, respectively. From Qena were
0.690±0.170 and 0.309±0.088, respectively. In Kous were 1.124±0.209 and 0.278±0.058, respectively. In Luxor were 0.598±0.087 and
0.367±0.085, respectively. In Esna were 0.446±0.079 and 0.275±0.050, respectively.
