“12th Class Chemistry Chapter 16 Quiz: Environmental Chemistry” covers the chemical processes that take place within the environment, especially those involving air, water, and soil quality. The present chapter deals with the effects of human activities on the environment, the role of chemicals in environmental pollution, and how to control and reduce the causes of environmental degradation. Knowledge of environmental chemistry is important for dealing with various issues relating to climate change and sustainability. Learn more with our MDCAT Quiz and free flashcards to ace this very important chapter.
Environmental Pollution and Its Impact
Environmental pollution is the major concern today, mainly due to human-induced activities like industrial emissions, agricultural practices, and improper waste management. In this chapter, you will learn about various types of pollutions such as air, water, soil, and noise pollution.
Air pollution is caused by the emission of dangerous chemicals such as carbon monoxide, sulfur dioxide, and nitrogen oxides into the atmosphere. The sources of these pollutants are the burning of fossil fuels in vehicles and industries. On the other hand, water pollution results from the discharge of dangerous chemicals such as heavy metals, pesticides, and untreated sewage into water bodies.
