What does the "synergistic effect" in toxicology imply?

The concept of the "synergistic effect" in toxicology refers to the situation where two or more substances, when combined, produce a toxic effect that is greater than the sum of their individual toxic effects. This means that the interaction between the substances enhances their overall toxicity, leading to outcomes that can be more severe than what would be anticipated by considering each substance's effects in isolation.

Understanding this principle is crucial in toxicology because it highlights potential risks in scenarios where multiple chemicals are present. For example, two substances that might not be harmful on their own can result in a significantly higher level of toxicity when they interact with each other, posing greater health risks to exposed individuals or the environment.

Recognizing synergistic effects is important for risk assessment and management in various fields, including pharmaceuticals, environmental health, and occupational safety, where individuals may be exposed to combinations of different substances.
