What are the main processes involved in the biological fate of toxicants?

The main processes involved in the biological fate of toxicants include absorption, distribution, storage, and elimination.

Absorption refers to how toxicants enter the body, which can occur through various routes such as ingestion, inhalation, or dermal exposure. Once absorbed, toxicants are then distributed throughout the body via the bloodstream or lymphatic system. Different tissues may have varying affinities for certain toxicants, leading to the storage of these substances in specific organs or fat tissues. Finally, the elimination process involves the body’s mechanisms to expel toxicants, which may occur through urine, feces, sweat, and exhalation.

Understanding these processes is crucial for assessing the potential impact of toxicants on human health and for developing strategies to mitigate their effects. Other options may focus on partial aspects of the processes or use terminologies that do not encompass the entire biological fate, which is why they do not accurately reflect the complete picture.
