Question 1:
What is e-waste?
Explanation: E-waste refers to waste generated from electronic devices, including computers, mobile phones, televisions, and other electronic equipment. E-waste can contain hazardous substances, such as lead, mercury, cadmium, and brominated flame retardants, which can pose risks to human health and the environment if not managed properly.
Question 2:
Why is e-waste management important?
Explanation: E-waste management is important to reduce the amount of electronic waste generated. E-waste contains valuable materials that can be recovered and reused, reducing the need for raw materials and the environmental impacts associated with their extraction. Proper e-waste management also helps prevent the release of hazardous substances into the environment and protects human health.
Question 3:
What is the first step in e-waste management?
Explanation: The first step in e-waste management is the collection and segregation of e-waste. This involves separate collection systems for electronic waste and proper sorting based on different types of electronic devices. Collection and segregation are crucial for effective recycling and proper disposal of e-waste.
Question 4:
Which of the following is a sustainable approach for managing e-waste?
Explanation: Repairing and refurbishing electronic devices is a sustainable approach for managing e-waste. It extends the lifespan of electronic devices, reduces the need for new production, and minimizes waste generation. Repairing and refurbishing also contribute to the circular economy by promoting reuse and resource conservation.
Question 5:
What are the potential environmental impacts of improper e-waste disposal?
Explanation: Improper e-waste disposal can lead to soil and water contamination with hazardous substances. When e-waste is not managed properly, toxic materials such as lead, mercury, and cadmium can leach into the soil and contaminate groundwater, posing risks to ecosystems and human health. It is essential to ensure proper recycling and disposal of e-waste to prevent these environmental impacts.
