With reference to Benzo(a)pyrene, consider the following statements: ...
Benzo(a)pyrene is a polycyclic aromatic hydrocarbon (PAH) that is considered to be a highly toxic and carcinogenic substance. It is formed during the incomplete combustion of organic matter, such as burning coal, oil, wood, or other organic materials.
Let's examine each statement given in the question:
1. It is released due to the incomplete combustion of organic matter.
- This statement is correct. Benzo(a)pyrene is released into the environment when organic matter is burned incompletely. This can occur in various situations, including industrial processes, vehicle emissions, and even domestic activities like cooking and heating.
2. It is found in grilled and smoked meat and fish.
- This statement is also correct. When meat or fish is grilled or smoked, the high temperatures and direct heat can lead to the formation of benzo(a)pyrene. This compound can then adhere to the surface of the food, leading to potential exposure when consumed.
3. It is a monitored pollutant under the National Ambient Air Quality Standards.
- This statement is correct as well. Benzo(a)pyrene is considered to be a hazardous air pollutant and is monitored under the National Ambient Air Quality Standards in many countries, including the United States. The monitoring of this pollutant helps to assess the air quality and potential health risks associated with its presence in the atmosphere.
In conclusion, all three statements given in the question are correct. Benzo(a)pyrene is indeed released due to the incomplete combustion of organic matter, it can be found in grilled and smoked meat and fish, and it is monitored as a pollutant under the National Ambient Air Quality Standards.

With reference to Benzo(a)pyrene, consider the following statements: ...
- Benzo[a]pyrene is a polycyclic aromatic hydrocarbon and the result of incomplete combustion of organic matter at temperatures between 300 °C (572 °F) and 600 °C (1,112 °F). The main source of atmospheric BaP is residential wood burning. It is also found in coal tar, in automobile exhaust fumes (especially from diesel engines). BaP is discharged in wastewater by industries such as smelters, particularly iron and steel mills and aluminum smelters, in all smoke resulting from the combustion of organic material (including cigarette smoke), and in charbroiled food or grilled meats. A 2001 National Cancer Institute study found levels of BaP to be significantly higher in foods that were cooked well-done on the barbecue, particularly steaks, chicken with skin, and hamburgers.
- BaP has been identified as a prime carcinogen in cigarette smoke According to the National Ambient Air Quality Standards (NAAQS), there are twelve major pollutants including PM 10, PM 2.5, Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Carbon Monoxide (CO), Ozone (O3), Ammonia (NH3), Benzene (C6H6), Benzo (a) Pyrene (BaP), Arsenic (As), Nickel (Ni) and Lead (Pb). Hence the correct option is (d).
