Detailed explanation-1: -A term used to describe how exposure to more than one chemical might affect the body. Used to explain long-term exposure to mixtures of chemicals, such as pesticides or additives.
Detailed explanation-2: -Toxic agent-induced immunostimulation can cause autoimmune diseases, in which healthy tissue is attacked by an immune system that fails to differentiate self-antigens from foreign antigens. For example, the pesticide dieldrin induces an autoimmune response against red blood cells, resulting in hemolytic anemia.
Detailed explanation-3: -The hazard index can be used to identify the most risky substances in a mixture, i.e. the chemicals that have the highest health risks based on toxic potential and estimated or measured exposure.
