What does toxicodynamics examine?

Toxicodynamics specifically focuses on the interaction between toxic substances and biological systems. This field studies the effects of toxins on living organisms, looking at mechanisms of toxicity, the biochemical and physiological responses to chemical exposure, and how these substances can lead to adverse biological effects. Understanding toxicodynamics is essential for determining the risk associated with specific exposures, how toxins exert their effects at the cellular and systemic levels, and how they can lead to symptoms or injuries in an organism.

The other options pertain to different aspects of chemical safety and analysis rather than the interactions between toxins and biological systems. While methods of chemical analysis, safeguards against spills, and long-term storage are important considerations in handling toxic substances, they do not focus on the biological effects of toxins, which is the central concern of toxicodynamics.
