Review: Preventing Computer-Related Injuries

Which option lists two effective methods to prevent or reduce injuries from prolonged computer use?

• Ignore breaks and work longer to finish tasks faster

• Use an ergonomic chair and take regular short breaks to stretch

• Place the monitor far above eye level and hunch forward

• Keep wrists bent sharply while typing to increase speed

Which statement best defines e-waste?

• Any household trash that can be recycled

• Any electronic product, or product with electronic components, that has reached the end of its usable life cycle

• Only broken smartphones and laptops

• Leftover packaging from new electronics

Based on the definition of e-waste, which item would most likely become e-waste at the end of its life cycle?

• A glass bottle

• A wooden chair

• An old computer that no longer works

• A cotton T-shirt

The image showing a recycling bin overflowing with old devices next to the question 'What causes E-waste?' mainly suggests which idea?

• E-waste is only caused by food waste

• Electronic products eventually reach the end of their usable life and are discarded

• Recycling bins should only hold paper products

• E-waste can be eaten safely

Which option is a negative environmental effect caused by electronic devices?

• Soil Contamination

• Improved soil fertility

• Cleaner air

• Increased biodiversity

A community notices more respiratory problems near an area where electronic waste is burned. Which listed effect best explains this outcome?

• Water pollution

• Air pollution

• Soil contamination

• Harm to plants only

Which action during informal e-waste disposal most directly releases dust particles or toxins into the air?

• Carefully storing old devices in sealed containers

• Dismantling, shredding, or melting the materials

• Wiping data from devices before recycling

• Transporting e-waste in covered trucks

Dioxins released from e-waste processing primarily harm which part of the human body?

• Digestive system

• Respiratory health

• Skeletal system

• Vision

What is a likely environmental impact when e-waste contaminates soil?

• Increase in local air temperature

• Purification of nearby rivers

• Contamination of underlying groundwater

• Faster growth of native plants

A community burns old electronics in open pits to recover metals. Based on the information, which risk is most immediate and why?

• Soil becomes too dry because heat evaporates water

• Air pollution from released toxins like dioxins harming lungs

• Groundwater instantly turns acidic

• Electronics stop working nearby due to smoke
