Abstract

The current study has been conducted to evaluate biochemical, hematological and histopathological alterations in rats following one month of inhalation exposure to NPK (nitrate, phosphate, potassium) 15.15.15 fertilizer. 24 male Wistar rats were randomly divided into four groups (A, B, C and D). Group A was served as control, whereas B, C and D groups have been exposed to aerosol of different doses (10 mg/m3, 30 mg/m3 and 50 mg/m3, respectively) of NPK 15.15.15 fertilizer during 30 min/day for one month. At the end of the experiment, rats were sacrificed. Blood samples were collected to evaluate biochemical and hematological parameters. Liver and lung tissues were served to evaluate oxidative stress statue and histopathological alterations.

Our results showed that inhalation exposure of rats to NPK 15.15.15 fertilizers, especially at high dose (50 mg/m3) resulted in a significant (P = 0,05) elevation of biochemical hepatic markers: Aspartate aminotransferase and Alanine transaminase, and a highly significant (P = 0,01) elevation of alkaline phosphatase. In addition, there were significant changes in hematological parameters revealed mainly by a highly significant (P = 0,01) increase of lymphocytes in both groups C and D groups, and significant decreases (P = 0,05) in all of: red blood cells, hematocrit, and hemoglobin in rats of group D compared to control. Furthermore, the inhalation exposure of rats to NPK 15.15.15 fertilizers induced lung oxidative stress revealed by the reduction of anti-oxidant enzymes (Glutathione peroxidase, reduced glutathione and superoxide dismutase); besides we have observed significant histopathological alterations revealed mainly by inflammatory cell infiltration in liver and lung tissues.

The inhalation exposure to important doses of NPK 15.15.15 fertilizer can damage the liver and lung tissues by altering biochemical, hematological and oxidative stress parameters.
