What is the purpose of the LD50 test in toxicology?
Answer: A. To identify the lethal dose for 50% of a test population
The LD50 (Lethal Dose 50%) test is a standard measure in toxicology used to determine the dose of a substance that is lethal for 50% of a test population. It provides a quantitative estimate of the acute toxicity of a chemical, indicating its short-term poisoning potential. This value helps in classifying substances and setting safety guidelines.
Physiologically based pharmacokinetic (PBPK) modeling is most useful in toxicology for:
Answer: B. Extrapolating toxicokinetic data across species, routes, and dose levels
PBPK models use physiological parameters (organ volumes, blood flows) and chemical-specific parameters to extrapolate internal dose across species (animal to human), routes, and dose levels in risk assessment.
GHB (gamma-hydroxybutyrate) is particularly challenging in forensic toxicology because:
Answer: B. It is an endogenous compound with a short detection window (4–8 hours in urine)
GHB is an endogenous brain metabolite with a short half-life (~30 minutes) and narrow detection window (4–8 hours in urine), making it difficult to detect in drug-facilitated sexual assault cases.
What is systemic toxicology primarily concerned with?
Answer: B. The effects of toxins on individual organs and organ systems
Systemic toxicology is primarily concerned with studying the effects of toxins on individual organs and organ systems throughout the body. This field investigates how toxic substances target and damage specific biological systems, such as the nervous system, liver, kidneys, or reproductive system, and the mechanisms by which these effects occur. It provides a comprehensive understanding of organ-specific toxicity.
