Toxicology experiments are scientific research that studies the effects of poisons on living organisms, reveals their toxicity mechanisms, and evaluates potential health risks. This field includes research on acute toxicity, subacute toxicity, chronic toxicity, mutagenicity and carcinogenicity. Experiments usually use models such as mice, rats, and cell culture, and adopt various toxicity assessment methods, such as biochemical testing, histopathology, and gene expression analysis. Toxicology experiments provide key information for drug safety assessment, environmental pollution research, and toxicology research.
