Several methods are employed in the early detection of toxic substances, including:
Biomonitoring: The measurement of toxic substances or their metabolites in biological specimens such as blood, urine, or hair. Biosensors: Devices that combine a biological component with a physicochemical detector to identify the presence of toxicants. Analytical techniques: Methods such as gas chromatography, mass spectrometry, and high-performance liquid chromatography are used to detect and quantify toxic substances. Point-of-care testing: Portable and rapid testing methods that can be used at the site of exposure or in clinical settings to provide immediate results. Wearable devices: Innovations in technology have led to the development of wearable sensors that continuously monitor for toxic exposures.
