When did benzene become carcinogenic?

Benzene. The evidence for carcinogenicity of benzene in humans was evaluated by the IARC in 1982 as follows: “It is established that human exposure to commercial benzene or benzene-containing mixtures can cause damage to the haematopoietic system, including pancytopenia.

How much benzene is toxic?

Brief exposure (5–10 minutes) to very high levels of benzene in air (10,000–20,000 ppm) can result in death. Lower levels (700–3,000 ppm) can cause drowsiness, dizziness, rapid heart rate, headaches, tremors, confusion, and unconsciousness.

Is benzene a carcinogen sunscreen?

The chemical benzene, is a known carcinogen. The benzene appears to be a result of manufacturing problems. The benefits of using sunscreen likely outweighs the risks from benzene.

Why is benzene so toxic?

The radiomimetic nature of benzene and its ability to induce different sites of neoplasia indicate that formation of oxygen radicals is a major cause of benzene toxicity, which involves multiple mechanisms including synergism between arylating and glutathione-depleting reactive metabolites and oxygen radicals.

What is an acute effect of benzene on the human body?

Acute (short-term) inhalation exposure of humans to benzene may cause drowsiness, dizziness, headaches, as well as eye, skin, and respiratory tract irritation, and, at high levels, unconsciousness.

Is benzene dangerous?

Benzene is a carcinogenic substance that is present in a great number of modern products and industries. It is formed through both natural processes and human activities, but importantly, high level of exposure to benzene can be quite dangerous.

What is chronic benzene?
