Usage

General Description

13(H)-dibenzo[a,i]carbazole is a polycyclic aromatic hydrocarbon and environmental pollutant that is formed during the incomplete combustion of organic materials such as fossil fuels and tobacco smoke. It is a potent carcinogen and mutagen, with the ability to cause DNA damage and disrupt cellular function. It is also known to induce the production of reactive oxygen species, leading to oxidative stress and inflammation. Exposure to 13(H)-dibenzo[a,i]carbazole has been associated with an increased risk of lung, liver, and skin cancers, as well as developmental and reproductive toxicity. As a result, it is considered a harmful environmental contaminant and efforts are being made to minimize exposure and mitigate its effects.
