Detailed explanation-1: -Synergistic effects. Sometimes a chemical combination produces a health effect that is greater than the sum of the individual effects. This kind of interaction is called synergism. An example of synergism is the increased risk of developing lung cancer caused by exposures to both cigarette smoking and asbestos.
Detailed explanation-2: -"Mixture toxicity” describes the effect that occurs when the toxicity of a combination of different chemicals is higher than the toxicity of each of the individual substances. However, this is not commonly the case. “Mixture toxicity” occurs when chemicals have a common toxicity.
