FAQs on Short Tricks: Environmental Chemistry 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 understanding the impact of human activities on these processes and finding solutions to environmental issues through the application of chemical principles.
| 2. What are the major pollutants in the environment? | |
Ans. The major pollutants in the environment are air pollutants such as carbon monoxide, nitrogen oxides, sulfur dioxide, and particulate matter; water pollutants including heavy metals, pesticides, and organic pollutants; and soil pollutants like heavy metals, pesticides, and industrial chemicals. These pollutants can have detrimental effects on human health and ecosystems.
| 3. How does environmental chemistry contribute to sustainable development? | |
Ans. Environmental chemistry plays a crucial role in sustainable development by providing scientific knowledge to assess and mitigate the impact of human activities on the environment. It helps in developing cleaner technologies, analyzing pollutants, understanding their fate and transport, and developing strategies for pollution prevention and control. This knowledge enables us to make informed decisions and take actions that promote sustainable practices.
| 4. What are the sources of greenhouse gases and their impact on climate change? | |
Ans. Greenhouse gases (GHGs) are primarily emitted from human activities such as burning fossil fuels, deforestation, and industrial processes. Carbon dioxide (CO2) is the most significant GHG, followed by methane (CH4) and nitrous oxide (N2O). These gases trap heat in the atmosphere, causing the greenhouse effect and contributing to global warming and climate change. The increase in GHG concentrations leads to rising temperatures, sea-level rise, extreme weather events, and other environmental impacts.
| 5. How can environmental chemistry help in the remediation of contaminated sites? | |
Ans. Environmental chemistry provides the knowledge and tools to assess the extent and nature of contamination in soil and water. It helps in understanding the behavior and fate of pollutants, evaluating the risks associated with contaminated sites, and developing effective remediation strategies. Techniques such as bioremediation, phytoremediation, and chemical oxidation can be employed based on the principles of environmental chemistry to clean up contaminated sites and restore their ecological balance.
