When disposing of computer equipment, which of the following can present an environmental hazard?

Bezels are typically made of ABS plastic, which poses minimal environmental risk and is not classified as a hazardous material under e-waste regulations.

SATA cables consist primarily of copper conductors and plastic insulation and do not contain the heavy metals or toxic compounds that trigger regulated disposal requirements.

Cat5 cables are composed of copper wire and polyethylene or PVC insulation and do not contain significant quantities of regulated hazardous substances compared to CRT components.

CRT monitors contain several pounds of lead in the glass funnel and neck of the tube, as well as phosphor coatings that can leach toxic substances into soil and groundwater if landfilled. Because of these hazardous materials, CRTs are classified as e-waste and regulated under EPA guidelines and many state environmental laws. Improper disposal can result in environmental contamination and legal liability for the organization.
