Several toxins are commonly quantified in toxicology studies: - Heavy Metals: Lead, mercury, arsenic, and cadmium are often measured due to their significant health risks. - Pesticides: Organophosphates, carbamates, and pyrethroids are quantified to assess agricultural and environmental safety. - Pharmaceuticals: Drugs and their metabolites are measured to study their toxicity and pharmacokinetics. - Industrial Chemicals: Compounds like benzene, toluene, and formaldehyde are quantified to monitor occupational exposure.
