Pre-analytical for biological monitoring of manganese
Abstract:
Manganese is an essential element but it may result in a toxic event if the workers are excessively exposed to this element. Monitoring of biological Mn exposure is therefore important. The careful preparation for Mn analysis is necessary. In order to get a correct protocol for sampling and storage of the biological samples, identification of the possible contamination source is necessary. This study is concerned with the monitoring procedure of manganese especially the sources of contamination sampling, sample transportation and storage. The results of the study shows that some kinds of needles and anticoagulants might be the main sources of contamination of specimen. It is important to avoid these contamination in performing biological monitoring on workers exposed to manganese.
Insights
Excessive manganese exposure can cause toxicity. This study identifies needles and anticoagulants as key contamination sources, crucial for accurate biological monitoring of manganese exposure in workers.
Area of Science:
- Occupational Health
- Environmental Science
- Analytical Chemistry
Background:
- Manganese (Mn) is an essential trace element vital for numerous physiological processes.
- However, excessive occupational exposure to manganese can lead to neurotoxicity and other adverse health effects.
- Reliable biological monitoring is essential for assessing worker exposure and preventing manganese toxicity.
Purpose of the Study:
- To identify potential sources of contamination during the sampling, transportation, and storage of biological specimens for manganese analysis.
- To establish a robust protocol for biological monitoring of manganese exposure in occupational settings.
- To ensure the accuracy and reliability of manganese level measurements in biological samples.
Main Methods:
- Investigated various sampling materials, including different types of needles, for their potential to introduce manganese contamination.
- Assessed the impact of anticoagulants commonly used in blood collection on manganese concentrations.
- Evaluated standard procedures for sample transportation and storage to identify and mitigate contamination risks.
Main Results:
- Specific types of needles were identified as significant sources of manganese contamination in biological samples.
- Certain anticoagulants were found to contribute to elevated manganese levels, potentially skewing exposure assessments.
- Improper sample handling and storage can further compromise the integrity of manganese measurements.
Conclusions:
- Careful selection of sampling materials, particularly needles and anticoagulants, is critical to avoid pre-analytical contamination.
- Implementing standardized protocols for sample collection, transportation, and storage is paramount for accurate biological monitoring of manganese.
- Minimizing contamination sources ensures reliable assessment of occupational manganese exposure, safeguarding worker health.
