Summary
A new method monitors zeranol in workplaces using air, dermal, and bulk samples. High-performance liquid chromatography ensures accurate detection, safeguarding worker health.
Area of Science:
- Environmental Science
- Occupational Health
- Analytical Chemistry
Background:
- Concerns exist regarding health effects of zeranol exposure.
- Monitoring zeranol in the workplace is crucial for worker safety.
Purpose of the Study:
- To develop and evaluate a sampling and analytical method for monitoring zeranol in the work environment.
- To ensure sensitive and specific detection of zeranol in various environmental matrices.
Main Methods:
- Collection of air, area, hand/dermal, and bulk samples.
- Utilized high-performance liquid chromatography (HPLC) with UV and fluorescence detection.
- Evaluated sampling media, flow rates, extraction efficiencies, sample stability, and analytical parameters (LOD, LOQ, precision, accuracy).
Main Results:
- Developed a comprehensive sampling strategy for diverse workplace scenarios.
- Achieved low limits of detection (LOD) and quantitation (LOQ) using HPLC-UV (LOD: 0.007 µg/mL, LOQ: 0.02 µg/mL) and HPLC-Fluorescence (LOD: 0.05 µg/mL, LOQ: 0.15 µg/mL).
- Confirmed peak identity using retention time and dual-detector response.
Conclusions:
- The developed method is sensitive and specific for analyzing zeranol in workplace environmental samples.
- This method provides a reliable tool for assessing occupational exposure to zeranol.
- Implementation of this monitoring technique can help mitigate health risks associated with zeranol use.
