Harmful effects of the interaction between microplastic container, aluminuim foil and hot water on some physiological parameters using pigeon model

Due to common used of disposable food containers cuurrently.This study evaluated the toxicity resulted from the interaction between the boiling tap water, microplastic container , aluminuim foil with or without microwave radiation on some physiological and histological parameters in Pigeons. Forty pigeons were classified into four groups. The birds in group 1 drink tap water without boiling placed in the usual drinking bowl. The birds in group 2 received tap water in thermoplastics containers previously boiled in microwave oven for 5 minutes, whereas in group3, the birds drink boiled tap water that put in thermoplastics containers for 5 min and group 4 the birds drink boiled water placed in a covered bowl completely with aluminum foil for 5 minutes, in the last three groups when the water temperature drops to 27Cº placed in the usual drinking bowl .The experimental continued for 30 days. The blood test findings hemoglobin levels dramatically dropped in G2, G3, and G4 compared to G1. Granulocytes Percentage dramatically decreased at all test groups compared to G1, WBCs, Lymphocytes and Monocytes significantly increased in all treated groups. Lipid profile results showed LDL levels increased statistically significant in G2 than in G1, while liver profile only increased in ALT value at G3 compare G1. Histopathological sections of liver, kidney and testicular tissues revealed pathological changes in whole treated groups compared to control . It can be concluded that using of plastic container and Aluminum foils can be toxic when increased temperature with or without using microwave oven.
