FAQs on Environmental Chemistry in One Shot (NCERT) Video Lecture - Chemistry Class 11 - NEET

1. What is environmental chemistry?
Ans. Environmental chemistry is the study of chemical processes occurring in the environment, including the air, water, soil, and living organisms. It focuses on the understanding of how pollutants are formed, transported, and transformed in the environment, and how they impact human health and ecosystems.
2. How are pollutants formed in the environment?
Ans. Pollutants can be formed in the environment through various processes. Some primary sources of pollution are industrial emissions, vehicle exhausts, agricultural activities, and waste disposal. These activities release pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxides, heavy metals, and organic compounds into the environment.
3. What are the major sources of air pollution?
Ans. The major sources of air pollution include industrial emissions, vehicle exhausts, power plants, burning of fossil fuels, and agricultural activities. These sources release pollutants like carbon monoxide, sulfur dioxide, nitrogen oxides, particulate matter, and volatile organic compounds into the air, leading to air pollution.
4. How does environmental chemistry help in understanding the impact of pollutants on human health?
Ans. Environmental chemistry plays a crucial role in understanding how pollutants can affect human health. By studying the behavior and transformation of pollutants in the environment, scientists can determine their potential toxicity and how they can enter the human body. This knowledge helps in developing strategies to minimize exposure and mitigate the health risks associated with pollutants.
5. How does environmental chemistry contribute to the preservation of ecosystems?
Ans. Environmental chemistry provides insights into the impacts of pollutants on ecosystems. By studying the interactions between pollutants and living organisms, scientists can assess the potential harm to biodiversity, food chains, and overall ecosystem health. This information helps in developing strategies to prevent or minimize pollution and protect ecosystems for sustainable development.
