Question

Explain why benzene is carcinogenic and
toxic.​

Answer 1

$\huge\underline\frak{\fbox{AnSwEr :-}}$

Benzene and polycyclic aromatic compounds containing more than two benzene rings fused together are toxic and carcinogenic (cancer causing). Many polycyclic aromatic compounds are formed by incomplete combustion of organic materials like tobacco, coal and petroleum. In human body, benzene is oxidized to an epoxide. Benzopyrene is converted into an epoxy diol. These compounds undergo various biochemical reactions and can react with DNA and cause cancer.

Answer 2

Answer:

Because benzene is a volatile aromatic solvent, inhalation exposures predominate. The carcinogenic properties of benzene have long been recognized; an increased risk of leukemia has been shown in workers exposed to high levels of benzene. Benzene exposure is associated with myelodysplastic syndromes
