Accumulation And Histological Transformation In The Gills, Liver, Muscles, And Skin In Oreochromis Niloticus Induced By Mercury, Khalid Abdullah Al-Ghanim, Zubair Ahmad, Hmoud Fares Alkahem Al-Balawi, Fahad Al-Misned, Shahid Mahboob, El Amin Mohammad Suliman
Accumulation And Histological Transformation In The Gills, Liver, Muscles, And Skin In Oreochromis Niloticus Induced By Mercury, Khalid Abdullah Al-Ghanim, Zubair Ahmad, Hmoud Fares Alkahem Al-Balawi, Fahad Al-Misned, Shahid Mahboob, El Amin Mohammad Suliman
Turkish Journal of Veterinary & Animal Sciences
Specimens of Oreochromis niloticus (One control and 3 experimental groups) were fed diets mixed with different doses of mercury (control group = free of mercury; group 1 = 500 mg/kg; group 2 = 750 mg/kg, and group 3 = 1000 mg/kg) for 60 days in order to study its accumulation and histopathological alterations in the liver, gills, skeletal muscles, and skin. The results obtained revealed that mercury accumulation was significantly (P < 0.05) high in the liver and gills compared to the muscles and skin. The order of accumulation in these organs revealed to be liver > gills > muscles > skin. The fish fed various doses of mercury also showed histological alterations in these organs. Epithelial lifting and epithelial hypertrophy were seen in the gills of the …
Effects Of Heavy Metal Accumulation On The 96-H Lc_50 Values In Tench Tinca Tinca L., 1758, Syed Lal Shah, Ahmet Altindağ
Effects Of Heavy Metal Accumulation On The 96-H Lc_50 Values In Tench Tinca Tinca L., 1758, Syed Lal Shah, Ahmet Altindağ
Turkish Journal of Veterinary & Animal Sciences
The effects of already accumulated heavy metals (Hg, Cd, Pb) in the body of tench on the 96-h LC_50 values of the respective heavy metals were studied. The body concentration of mercury, cadmium and lead was 0.011, 0.32 and 1.59 mg/g respectively, and their 96-h LC_50 values were 1.0, 6.5 and 300.0, ppm, respectively. The general accumulation order of heavy metals and their respective 96-h LC_50 values were Hg< Cd< Pb. It was observed that the fish with lowest body concentration of heavy metal showed the lowest 96-h LC_50 value of the respective heavy metal and vice versa. This close relationship showed that the previous body accumulation of heavy metals has a direct effect on the 96-h LC_50 values of the respective heavy metals and the susceptibility of fish.
Effect Of Cadmium Accumulation On Total Protein Levels In Tilapia Nilotica, Mustafa Kalay, Cahi̇t Erdem
Effect Of Cadmium Accumulation On Total Protein Levels In Tilapia Nilotica, Mustafa Kalay, Cahi̇t Erdem
Turkish Journal of Veterinary & Animal Sciences
The aim of the present study was to determine the accumulation of cadmium in different tissues of Tilapia nilotica and to establish the influence of this accumulation on total protein levels in liver and kidney tissues. At the end of each experimental period; gill, liver and kidney tissues from the animals were dissected and their cadmium accumulation was determined using atomic absorbtion spectrophotometry. Liver and kidney tissues were homogenised to determine total protein levels. The protein contents of the tissue homogenates were determined by the Lowry method. Cadmium accumulation was higher in the gill, liver and kidney tissues. Cadmium primarily …
Effects Of Different Concentrations Of Copper Alone And A Copper + Cadmium Mixture On The Accumulation Of Copper In The Gill, Liver, Kidney And Muscle Tissues Of Oreochromis Niloticus (L.), Baybars Sağlamti̇mur, Bedi̇i̇ Ci̇ci̇k, Cahi̇t Erdem
Effects Of Different Concentrations Of Copper Alone And A Copper + Cadmium Mixture On The Accumulation Of Copper In The Gill, Liver, Kidney And Muscle Tissues Of Oreochromis Niloticus (L.), Baybars Sağlamti̇mur, Bedi̇i̇ Ci̇ci̇k, Cahi̇t Erdem
Turkish Journal of Veterinary & Animal Sciences
Experiments were conducted in two series for 1, 7, 15 and 30 days. In the first series, fish were exposed to 0.1, 0.5, 1.0 and 5.0 ppm of copper and in the second series to 0.1 + 0.05, 0.5 + 0.1, 1.0 + 0.5 and 5.0 + 1.0 ppm of copper and cadmium mixtures. No mortalities were observed during the experimental period. Accumulation of copper in the tissues and organs increased with increasing concentrations of copper and with longer exposure periods. Copper accumulation associated with copper + cadmium mixtures in the gill, liver, kidney and muscle tissues varied with the …
