Carcinogenity and toxicity

 

Benzene and polycyclic aromatic hydrocarbons (PAH) are ubiquitous environmental pollutants generated during incomplete combustion of coal oil, petrol and wood. Some PAH originate from open burning, natural seepage of petroleum and coal deposits and volcanic activities. They are toxic, mutagenic and carcinogenic. It has hematological. immunological and neurological effect on humans. They are radiomimetic and prolonged exposure leads to genetic damage.Some of the examples of PAH are.

ā€œLā€ shaped polynuclear hydrocarbons are much more toxic & carcinogenic


Found in cigarette smoke Found in tobacco and cigarette and charcoal boiled food


Found in gasoline exhaust and barbaccued food
