Problem
Under normal conditions, animals are often exposed to mixtures of toxicants. Mixing toxicants often results in some form of toxicological interactions. A toxicological interaction is one in which exposure to two or more chemicals results in a biological response quantitatively or qualitatively different from that expected from the actions of each chemical alone. Interactions may occur by: - alterations in absorption - protein binding - biotransformation Using an appropriate diagram explain the likely responses that can occur when two or more chemicals are combined.
