Question

Now a days we find E-waste on large scale. Explain how is harmful for us

Answer 1

Electronic waste also called as e waste is nothing but any and all electronic items needed to be disposed of. This includes computing devices such as tablets, iPods, PCs, laptops, televisions and all home appliances. In recent years, as technology continued to advance the amount of e-waste produced has also doubled up. Electronic waste is a common, informal name for electronic products approaching the end of their useful life. The current and the future production of e-waste, the potential environmental problems associated with their disposal and management practices are discussed whereas the existing e-waste management. E-wastes are considered dangerous, as certain components of some electronic products contain materials that are harmful, depending on their condition and density. The harmful content of these materials poses a threat to human health and environment.

Harmful Effects of Electronic Waste:

Lead- Environmentalists all over the world claim that the presence of lead in electronic wastes such as television, PC monitors, and LEDs can cause serious diseases related to brain, kidney, reproductive system and entire nervous system. Specifically speaking, lead in the environment disrupts the natural functions of water and soil systems.

Mercury- Mercury has a toxic affect on both human and environment health. A small amount of it exists in CFLs, televisions and in refrigeration units. When the said e-waste is dumped into the landfills and water bodies the elemental form of mercury gets easily transferred into local environments. When combined with organics, anaerobic breakdown takes place and this causes the production of highly toxic methyl mercury.

Cadmium- Cadmium causes cancer to humans and when comes in contact with the environment, it rapidly degrades the health of the soil causing flow of effects to local ecosystems. When the electronic waste containing cadmium burns, it releases a lethal gas which on prolonged exposure causes lung failure.

E-waste also contains toxic and hazardous materials including mercury, lead, cadmium, beryllium, chromium, and chemical flame retardants, which have the potential to leach into our soil and water. Electronic Recyclingrecovers valuable materials from old electronics that can be used to make new products.

Answer 2

e waste means electronic waste
electronic waste means mobile TV laptop computer if we use in limit then only the e waste will decrease. now a days e waste are very major if we use less mobile and see less TV the machine will remain well then only e waste decrease

when e waste is warmed up toxic chemicals are released into the air damaging the atmosphere the damage to the atmosphere is one of the biggest environmental impact from e waste when w e waste is thrown away in landfills their toxic material seep into groundwater affected both land and sea animal
