Answer 1

Answer:

hope this will help you.. follow me!

Explanation:

Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for refurbishment, reuse, resale, salvage recycling through material recovery, or disposal are also considered e-waste. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution.

Electronic scrap components, such as CPUs, contain potentially harmful materials such as lead, cadmium, beryllium, or brominated flame retardants. Recycling and disposal of e-waste may involve significant risk to health of workers and their communities

Answer 2

Using computer components manufacturers circuit boards for medical and mobile devices and fire hazards are:

• Environmental Hazard Cathode meter tubes (used on TVs, computer monitors, ATMs, video cameras, etc.).
• Prolonged exposure to lead on printed circuit boards and computer and television screens can damage the central nervous system, and children are at risk of developing these harmful effects.
• Television and computer monitors use cathode ray tubes (CRTs) that contain significant amounts of lead.
• Sensors, slides, switches (eg printed circuit boards and measuring devices), medical devices, lights, cell phones, and batteries.
• Hexavalent VI chromium/chromium VI- Chromium VI is still used to prevent corrosion of green and electric plates Mercury is used in thermostats, sensors, relays, switches (eg on printed circuit boards and measuring machines), cell phones, and batteries.
• Hexavalent chromium/chromium VI is still used to protect the rust of raw metal plates and tanks and as a decoration or reinforcement for steel houses.
