Consider the following statements with respect to the Air Pollutants:1...
• Statement 2 and 3 are incorrect: Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact. Ground level ozone is a prominent example of a secondary pollutant. Secondary pollutants are generally more harmful.
Air Pollutants
• Air pollution occurs when harmful substances including particulates and biological molecules are introduced into Earth’s atmosphere. It may cause diseases, allergies or death of humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. Human activity and natural processes can both generate air pollution.
• An air pollutant is a substance in the air that can have adverse effects on humans and the ecosystem. The substance can be solid particles, liquid droplets, or gases. This pollutant can be of natural origin or manmade. Pollutants are classified as primary or secondary.
• The pollutants that are emitted directly from a combustion process – or the products of combustion - are called “primary pollutants” such as ash from a volcanic eruption. Other examples include carbon monoxide gas from motor vehicle exhaust, or the sulfur dioxide released from factories.
• Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact. Ground level ozone is a prominent example of a secondary pollutant. Secondary pollutants are generally more harmful.

Consider the following statements with respect to the Air Pollutants:1...
Air Pollutants
Air pollutants are substances present in the atmosphere that can cause harm to living beings and the environment. They can be classified into two categories - primary and secondary pollutants.
Primary Pollutants
Primary pollutants are those that are directly emitted into the atmosphere. They are usually produced from a process, such as burning fossil fuels or ash from a volcanic eruption. Examples of primary pollutants include carbon monoxide, sulfur dioxide, nitrogen oxides, and particulate matter.
Secondary Pollutants
Secondary pollutants are not emitted directly but are formed when primary pollutants react with other substances in the atmosphere. They are usually less harmful than primary pollutants. Examples of secondary pollutants include ground-level ozone, sulfuric acid, and nitric acid.
Ground-level Ozone
Ground-level ozone is a prominent example of a secondary pollutant. It is formed when nitrogen oxides and volatile organic compounds react with sunlight. Ground-level ozone can cause respiratory problems, particularly in people with asthma or other lung diseases.
Conclusion
In conclusion, statement 1 is incorrect as it refers to primary pollutants instead of secondary pollutants. Statement 2 is correct as secondary pollutants are usually less harmful than primary pollutants. Statement 3 is incorrect as ground-level ozone is a secondary pollutant, not a primary pollutant. Therefore, the correct answer is option B.
