An Exploratory Study of the Metabolite Profiling from Pesticides Exposed Workers

Area of Science:

• Environmental Health
• Toxicology
• Biochemistry

Background:

• Pesticide use is increasing, posing risks to human health and the environment.
• Occupational pesticide exposure is linked to toxic effects including infertility, hormonal disorders, and cancer.

Purpose of the Study:

• To investigate the metabolic profile of individuals occupationally exposed to pesticides.
• To identify potential novel biomarkers of pesticide exposure using metabolomics.

Main Methods:

• Non-targeted metabolomics analysis of plasma and urine samples from exposed and non-exposed individuals.
• Utilized ultra-performance liquid chromatography coupled with mass spectrometry (UPLC-MS).
• Employed multivariate statistical analyses (PCA, PLS-DA, OPLS-DA) and ROC curve analysis.

Main Results:

• Identified 21 discriminating metabolites in plasma and 17 in urine.
• Demonstrated good sample separation between exposed and non-exposed groups.
• Revealed significant alterations in lipid and amino acid metabolism.

Conclusions:

• Metabolomics is a valuable tool for understanding complex biological responses to pesticide exposure.
• Identified potential biomarkers for occupational pesticide exposure.
• Highlights the impact of pesticides on metabolic pathways, particularly lipid and amino acid metabolism.
