In histology, biomonitoring typically involves several steps: 1. Sample Collection: Tissues are collected from living subjects through biopsies or from cadavers during autopsies. 2. Sample Preparation: The collected tissues are fixed, embedded, sectioned, and stained to preserve their structure and make specific components visible under a microscope. 3. Analysis: Advanced techniques like immunohistochemistry, in situ hybridization, and mass spectrometry are used to identify and quantify chemicals and their effects on tissues.
