Cholinesterase inhibition and its association with hematological, biochemical and oxidative stress markers in chronic pesticide exposed agriculture workers

Abstract

The present study investigated the pesticide induced adverse health effects, hematological and biochemical alterations among agriculture workers. A cross sectional study of 51 agriculture workers and 54 unexposed subjects was carried out to evaluate hematological and biochemical alterations in blood. Pesticide exposed individuals were reported adverse clinical outcomes, including tingling, muscle pain, headache, skin disease, etc. A significant alterations in the level of hematological parameters, liver and renal dysfunctions markers and lipid profile suggested hematological, hepatic and renal dysfunctions. A significant decrease in the activity of acetylcholinesterase, reduced glutathione, superoxide dismutase, catalase and increased level of lipid peroxidation was also observed in these agriculture workers. Correlation coefficient analysis showed a positive correlation of chronic exposure with most of the hematological and biochemical parameters. The results demonstrate that the chronic exposure of pesticides cause reduction in the acetylcholinesterase activity and enhanced the risk of adverse clinical outcomes in agriculture workers.
