There are several types of human studies in toxicology, each with its own advantages and limitations:
Observational Studies: These include cohort, case-control, and cross-sectional studies. They observe and analyze existing data without intervening. Observational studies are useful for identifying associations between chemical exposure and health outcomes. Clinical Trials: These are experimental studies where participants are assigned to receive specific interventions. Clinical trials are often used to test the safety and efficacy of new drugs or treatments. Epidemiological Studies: These studies investigate the distribution and determinants of health-related states in specific populations. They are crucial for understanding how environmental and occupational exposures affect public health.
