why does benzene cause hemolysis of red blood cells?

Answer 1

RBCs have a phospholipid membrane like other cells of the body. Lipids are soluble in alcohols like benzene, so the membrane falls apart.

Answer 2

Hemolysis (or haemolysis)—from the Latin Hemo-, meaning blood, -lysis, meaning to break open— is the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid (plasma, in vivo).
The major effect of benzene from chronic (long-term) exposure is to the blood. Benzene damages the bone marrow and can cause a decrease in red blood cells, leading to anemia. It can also cause excessive bleeding and depress the immune system, increasing the chance of infection
Benzene is no longer used as an additive in gasoline but it is an important industrial solvent and precursor in the production of drugs, plastics, synthetic rubber, and dyes.
