Age is a critical factor in toxicological responses. Infants and the elderly are often more susceptible to toxicants due to their distinct physiological states. In infants, organ systems such as the liver and kidneys are not fully developed, impacting the metabolism and excretion of toxins. Conversely, in the elderly, decreased organ function and chronic health conditions can alter the body's ability to handle toxic exposures, necessitating adjusted safety thresholds for these populations.
