Biomonitoring involves the collection and analysis of biological samples such as blood, urine, saliva, or tissue. The process generally includes: - Sample Collection: Biological samples are collected from participants using standardized methods to ensure accuracy and comparability. - Laboratory Analysis: Advanced analytical techniques, including mass spectrometry and chromatography, are used to detect and quantify chemicals or their metabolites. - Data Interpretation: The results are interpreted in the context of known exposure levels and health outcomes to draw meaningful conclusions about cancer risk.
