What does the combined effect of toxins include?

This post was last edited by ylb913 on 2015-10-3 at 11:26. The combined effects of toxins mainly manifest in the following types: (1) Additive effect. The toxic effect when multiple poisons are present simultaneously is the sum of the individual toxic effects of each poison. For example, the irritant effect of most irritating gases is additive. (2) Multiplicative effect. The toxic effect when multiple poisons are present simultaneously exceeds the sum of their individual toxic effects. For example, when carbon monoxide and nitrogen oxides are present together, they exhibit a synergistic toxic effect. (3) Independent action. There are multiple pathways through which toxins can enter the body, and the mechanisms by which they affect the body and cause poisoning are unrelated to one another, with no influence between them. (4) Antagonistic effect. When multiple poisons are present simultaneously, the poisons present can weaken each other’s toxic effects, resulting in a toxicity level of the mixture that is lower than that of each poison acting alone.

In a production environment, multiple toxins are often present simultaneously, and the toxic effects resulting from two or more toxins acting on the body at the same time are referred to as the combined effect of toxins. The combined effects of poisons mainly manifest in the following types: (1) Additive effect. The toxic effect when multiple poisons are present simultaneously is the sum of the individual toxic effects of each poison. For example, the irritant effect of most irritating gases is additive. (2) Multiplicative effect. The toxic effect when multiple poisons are present simultaneously exceeds the sum of their individual toxic effects. For example, when carbon monoxide is present alongside nitrogen oxides, it exhibits a synergistic toxic effect. (3) Independent action. There are multiple pathways through which toxins can enter the body, and the mechanisms by which they affect the body and cause poisoning are unrelated to one another, with no influence between them. (4) Antagonistic effect. When multiple poisons are present simultaneously, the poisons present can weaken each other’s toxic effects, resulting in a toxicity level of the mixture that is lower than that of each poison acting alone.

The answer is upstairs.......
