Q

Affect of Mixtures

A

Additive:
Combined effect is equal to the sum of its constituents (1+3=4)organic solvents

Antagonistic:
Combined effect is less than the sum of its
constituents (1+ 3=2) acids and alkali/toxin and antidote

Potentiating:
One substance enhances effect of another (0+ 2=10) alcohol potentiates effects of many chlorinated hydrocarbons

Synergistic:
Combines effect significantly greater than the sum (2+ 2=20) asbestos exposure and smoking
