The implications of variability are profound in the field of toxicology:
1. Risk Assessment: Variability must be accounted for to ensure that safety guidelines protect the most vulnerable populations. 2. Personalized Medicine: Understanding genetic variability can lead to personalized approaches in medicine and public health, tailoring interventions to individual susceptibilities. 3. Regulatory Policies: Regulatory bodies need to consider variability to set exposure limits and guidelines that are inclusive of all population segments.
