Environmental Impact of Electronic Waste
The processes of dismantling and disposing of electronic waste in the third world lead to a number of environmental impacts as illustrated in the graphic. Liquid and atmospheric releases end up in bodies of water, groundwater, soil and air and therefore in land and sea animals – both domesticated and wild, in crops eaten by both animals and human, and in drinking water.
One study of environmental effects in Guiya, China found the following:
- Airborne dioxins – one type found at 100 times levels previously measured
- Levels of carcinogens in duck ponds and rice paddies exceeded international standards for agricultural areas and cadmium, copper, nickel, and lead levels in rice paddies were above international standards
- Heavy metals found in road dust – lead over 300 times that of a control village’s road dust and copper over 100 times
The environmental impact of the processing of different electronic waste components
| E-Waste Component | Process Used | Potential Environmental Hazard |
|---|---|---|
| Cathode ray tubes (used in TVs, computer monitors, ATM, video cameras, and more) | Breaking and removal of yoke, then dumping | Lead, barium and other heavy metals leaching into the ground water and release of toxic phosphor |
| Printed circuit board (image behind table - a thin plate on which chips and other electronic components are placed) | De-soldering and removal of computer chips; open burning and acid baths to remove final metals after chips are removed. | Air emissions as well as discharge into rivers of glass dust, tin, lead, brominated dioxin, beryllium cadmium, and mercury |
| Chips and other gold plated components | Chemical stripping using nitric and hydrochloric acid and burning of chips | Hydrocarbons, heavy metals, brominated substances discharged directly into rives acidifying fish and flora. Tin and lead contamination of surface and groundwater. Air emissions of brominated dioxins, heavy metals and hydrocarbons |
| Plastics from printers, keyboards, monitors, etc. | Shredding and low temp melting to be reused | Emissions of brominated dioxins, heavy metals and hydrocarbons |
| Computer wires | Open burning and stripping to remove copper | Hydrocarbon ashes released into air, water and soil. |

Famous quotes containing the words impact, electronic and/or waste:
“One can describe a landscape in many different words and sentences, but one would not normally cut up a picture of a landscape and rearrange it in different patterns in order to describe it in different ways. Because a photograph is not composed of discrete units strung out in a linear row of meaningful pieces, we do not understand it by looking at one element after another in a set sequence. The photograph is understood in one act of seeing; it is perceived in a gestalt.”
—Joshua Meyrowitz, U.S. educator, media critic. “The Blurring of Public and Private Behaviors,” No Sense of Place: The Impact of Electronic Media on Social Behavior, Oxford University Press (1985)
“Ideally, advertising aims at the goal of a programmed harmony among all human impulses and aspirations and endeavors. Using handicraft methods, it stretches out toward the ultimate electronic goal of a collective consciousness.”
—Marshall McLuhan (1911–1980)
“If thou fill thy brain with Boston and New York, with fashion and covetousness, and wilt stimulate thy jaded senses with wine and French coffee, thou shalt find no radiance of wisdom in the lonely waste of the pinewoods.”
—Ralph Waldo Emerson (1803–1882)
