Question

Polycyclic aromatic hydrocarbons enter our body via :

• A. air contaminated by wild fire
• B. air contaminated by coal tar
• C. foods that have been grilled
• D. all of these

Answer 1

The correct option is D all of these

PAHs are neutral, nonpolar molecules found in coal and in tar deposits. They are produced as well by incomplete combustion of organic matter. PAHs can also be produced geologically when organic sediments are chemically transformed into fossil fuels such as oil and coal.

PAHs can enter our body by inhaling contaminated air and consuming food that has been grilled on coal.
