Photochemical smog pollution does not contain:
- ozone
- nitrogen dioxide
- carbon dioxide
- PAN (Peroxy acyl Nitrate)
The Correct Option is C
Solution and Explanation
Photochemical smog is primarily composed of ozone (O3), nitrogen dioxide (NO2), volatile organic compounds (VOCs), and other pollutants, but it does not contain significant levels of carbon dioxide, which is a different type of pollutant often associated with climate change and greenhouse gas emissions.
So, the correct option is (C): carbon dioxide

Concepts Used:
Environmental Chemistry
Environmental chemistry is the study of chemical processes and their impacts on the natural environment. It is a multidisciplinary field that combines principles from chemistry, ecology, biology, and geology to understand the complex interactions between chemicals and living organisms.
Environmental chemists investigate how pollutants such as toxic metals, organic chemicals, and pesticides affect ecosystems, including soil, water, and air. They also develop methods to monitor and measure these pollutants, as well as techniques for their removal or remediation.
Environmental chemistry also examines the impact of natural processes on the environment, such as the cycling of nutrients and the chemical reactions that occur in the atmosphere, oceans, and soil. This research can inform policy decisions related to environmental protection and management.

Examples of environmental chemistry applications include studying the effects of acid rain on ecosystems, developing methods for treating contaminated water and soil, and understanding the sources and fate of greenhouse gases in the atmosphere.
Overall, environmental chemistry plays a crucial role in identifying and addressing environmental problems, and it is essential for ensuring a sustainable future for our planet.
