Diksha Courses Environmental Hazards of Electronic waste (E-waste) Assessment Environmental Hazards of Electronic waste (E-waste) by Diksha Courses - August 6, 2026August 6, 20260 E-Waste Management & Sustainable Development Goals: Practice MCQs with Detailed Explanations Electronic waste (e-waste) is one of the fastest-growing environmental and public health challenges globally. Understanding its sources, hazards, regulatory frameworks, and connection to the United Nations Sustainable Development Goals (SDGs) is essential for students, researchers, and competitive exam aspirants in Environmental Studies. This guide provides 15 multiple-choice questions (MCQs) complete with verified answers, context-rich explanations, and background information designed to help you master key concepts in e-waste management and sustainable resource production. Multiple Choice Questions & Detailed Answers Question 1 The goal of Responsible Consumption and Production is Goal Number: a. 9 b. 6 c. 12 d. 16 Answer: c. 12 Explanation: Sustainable Development Goal 12 (SDG 12) specifically targets “Responsible Consumption and Production.” It focuses on decoupling economic growth from environmental degradation, reducing resource use, and promoting sustainable supply chains and waste management systems. Question 2 Which of the following are reasons for the overconsumption of resources? a. Lifestyle changes b. Rise in income levels c. Increased rate of obsolescence of electrical and electronic goods d. All of these Answer: d. All of these Explanation: Rapid urbanization, higher disposable income, changing lifestyle patterns, and planned obsolescence (where devices are designed to become outdated quickly) collectively drive global overconsumption of raw materials and energy. Question 3 Which is the most environmentally sound method used for E-waste disposal? a. Landfills b. Reuse c. Recycle d. Burning Answer: c. Recycle Explanation: Proper recycling in specialized, authorized facilities ensures that valuable secondary raw materials (like gold, silver, and copper) are recovered safely without leaching toxic heavy metals into soil and groundwater or emitting hazardous pollutants into the atmosphere. Question 4 Which valuable commodity is prominently found in electrical wiring? a. Copper b. Nickel c. Acid d. Beryllium Answer: a. Copper Explanation: Copper is an exceptionally conductive non-ferrous metal widely used in power lines, telecommunications, and internal circuit wiring. Its high scrap value makes it one of the primary targets for recovery in e-waste recycling. Question 5 Approximately 70% of the total E-waste generated in India originates from: a. Electrical equipment b. Medical equipment c. Computer equipment d. Telecommunication equipment Answer: c. Computer equipment Explanation: Information Technology (IT) equipment, particularly personal computers, laptops, and servers, constitutes roughly 70% of India’s total e-waste volume. Telecommunication devices account for around 12%, while medical and household devices make up the remainder. Question 6 Different household wastes collected during everyday residential activities like cooking and cleaning are classified as: a. Industrial waste b. Agricultural waste c. Domestic waste d. Commercial waste Answer: c. Domestic waste Explanation: Domestic waste (a primary component of municipal solid waste) consists of everyday discarded items originating from residential households, including kitchen scraps, paper, packaging, and small household refuse. Question 7 How many Sustainable Development Goals (SDGs) were established by the United Nations? a. 15 b. 19 c. 17 d. 14 Answer: c. 17 Explanation: In 2015, the UN General Assembly adopted 17 interconnected Sustainable Development Goals as part of the 2030 Agenda for Sustainable Development, serving as a global blueprint for peace, prosperity, and environmental protection. Question 8 In 2016, which continent generated the highest total volume of E-waste? a. North America b. Asia c. Europe d. Africa Answer: b. Asia Explanation: According to the UN Global E-Waste Monitor report, Asia generated the highest absolute quantity of e-waste in 2016 (approximately 18.2 million metric tonnes), driven by large populations and rapid market growth in electronic devices. Question 9 The E-waste Management and Handling Rules (2012) in India were significantly amended in which year? a. 2013 b. 2016 c. 2014 d. 2015 Answer: b. 2016 Explanation: The Ministry of Environment, Forest and Climate Change (MoEFCC) notified the E-Waste (Management) Rules, 2016, which replaced the 2012 rules. The 2016 revision introduced Extended Producer Responsibility (EPR), bringing producers, dealers, and refurbishers under strict collection targets. Question 10 What does the abbreviation “E-Waste” stand for? a. Exclusive waste b. Environmental waste c. Electronic waste d. Excess waste Answer: c. Electronic waste Explanation: E-waste stands for Electronic Waste (or Waste Electrical and Electronic Equipment — WEEE). It encompasses all discarded electrical or electronic items, including computers, mobile phones, televisions, and kitchen appliances. Question 11 Which hazardous element is found in traditional medical equipment such as glass thermometers? a. Barium b. Lead c. Mercury d. Arsenic Answer: c. Mercury Explanation: Liquid-in-glass clinical thermometers and sphygmomanometers contain elemental mercury. Mercury is a bioaccumulative neurotoxin that poses severe health risks if spilled or improperly incinerated. Question 12 Which is considered the most harmful toxic metal released during the informal recycling of E-waste? a. Aluminium b. Lead c. Iron d. Copper Answer: b. Lead Explanation: Lead is extensively present in Cathode Ray Tube (CRT) glass monitors and printed circuit board soldering. Informal dismantling methods—such as open-air burning or primitive acid leaching—release heavy lead contaminants, causing irreversible brain and kidney damage. Question 13 Improper and unsafe disposal of E-waste damages which environment system? a. Air b. Water c. Soil d. All of these Answer: d. All of these Explanation: E-waste contamination impacts all environmental spheres: open burning releases carcinogenic fumes into the air, heavy metals leach into soil, and toxic runoffs corrupt surface and groundwater supplies (water). Question 14 Which of the following is a prominent consumer electronics manufacturer originating from India? a. Apple b. Sony c. Videocon d. Samsung Answer: c. Videocon Explanation: Apple (USA), Sony (Japan), and Samsung (South Korea) are multinational foreign corporations. Videocon was established in India as an industrial conglomerate manufacturing home appliances and electronics. Question 15 Standard global environmental benchmarks place annual E-waste generation across the world at approximately: a. 10 million ton b. 25 million ton c. 40 million ton d. 32 million ton Answer: c. 40 million ton Explanation: International research benchmarks estimate global annual e-waste generation between 40 to 50 million metric tonnes, with total volumes continuing to climb due to decreasing product lifespans and expanding digital infrastructure.

Extended Producer Responsibility (EPR) is an environmental policy strategy that holds electronics manufacturers and importers accountable for the entire lifecycle of their products, particularly during post-consumer collection, channelized recycling, and eco-friendly disposal. Why is informal E-waste recycling dangerous? Informal recycling uses unsafe techniques such as open-air burning, direct acid washing, and unequipped manual dismantling without protective equipment. This exposes workers and local ecosystems to toxic heavy metals like lead, mercury, cadmium, and beryllium. How does proper E-waste management support SDG 12? Proper e-waste management supports SDG 12 by reducing global waste generation through prevention, reduction, recycling, and reuse (the 4 Rs), preserving critical raw materials and preventing toxic contamination in natural ecosystems.
