Why is it important to properly dispose of CRTs?

Proper disposal of cathode ray tubes (CRTs) is crucial because they contain hazardous materials such as lead, cadmium, and barium. When CRTs are broken or improperly disposed of, these toxic substances can leach into the environment, posing serious health risks to humans and wildlife. Lead, for example, can lead to neurological issues and developmental problems, particularly in children. Therefore, following proper disposal protocols ensures that these harmful materials do not contaminate soil and water sources.

While aspects of recycling, obsolescence, and noise pollution are relevant to the discussion around CRTs, they do not address the primary health and environmental concern associated with improper disposal. Recycling can help manage materials sustainably, but the emphasis on safety regarding hazardous contents makes the correct answer pivotal in highlighting the direct risks posed by CRTs to both human health and the ecosystem.
