Electronic Equipment, disused electronic equipment are all electronic waste. E-waste includes
Refrigerator , Air conditioning , Washing machines, television sets, household appliances and computers, mobile phones and other communication products, the elimination of electronic products, these e-waste commonly known as "e-waste."
Harbin produce 7,000 tons of "e-waste"
The information age, the rapid development of electronic industry. Electronic information technology industry has become one of the fastest growing industries, the resulting e-waste is increasing, and experts predict the next 10 years -20 years will be the growth of electronic waste a new peak.
UNEP released a report, China is now the number of e-waste produced annually by 230 million tons, second only to the United States, 3 million tons. Data show that China's social possession TV has reached 350 million units, refrigerator, washing machine are respectively 130 million and 1.7 million units. And with the scientific and technological development and innovation, electronic product update speed will be faster and electronic products will shorten the life of the corresponding, which will enable the number of e-waste a linear growth.
Reporter recently from the City Environmental protection Board was informed that, in recent years, with people continuing the upgrading of living standards, the city created the "e-waste" populations are also rising. According to statistics, in 1991, Harbin, households had televisions, washing machines, fridge freezers number of 1.487 million, respectively, 92.68
Million and 468,000 units; in 1996 to 2.817 million, respectively, 1,509,800 and 909,900 units. Press
Home Appliances 10 -15 years of normal service life calculation, Harbin City, 2.88 million units a year at least three major home appliances discarded, while at least 146,700 computers, 546,000 mobile end of life. It is estimated that Harbin waste electrical and electronic products annually about 7,000 tons. Such a large number of "e-waste" should be how to deal with has become the environmentalists and the general community concerns.
"E-waste" of the types and hazards
A wide range of e-waste can be broadly divided into two categories: one is contained in the material is relatively simple, less environmentally harmful waste electrical and electronic products, such as refrigerators, washing machines, air conditioners and other appliances, and medical, research and electrical appliances, dismantling and disposal of such products is relatively simple; the other is contained in more complex materials, the larger the environmental hazards of waste electrical and electronic products, such as computers, TV picture tubes of lead, the computer components in the contains arsenic, mercury and other harmful substances. Raw materials in mobile phones arsenic, cadmium, lead and many other toxic and harmful substances.
According to experts, e-waste is a master of poison. For example, 1 15-inch
CRT Computer monitors to contain cadmium, mercury, hexavalent chromium, PVC plastics and brominated flame retardants and other harmful substances; computer batteries and switches containing chromium compounds and mercury, computer components also contain arsenic, mercury and other a variety of harmful substances; TV, refrigerator, phone and other electronic products contain lead, chromium, mercury and other heavy metals; laser printer and copier toner contains. If the waste discarded electronic products to the wilderness as a general waste or landfill area, which contained lead well will penetrate the soil and water pollution by plants, animals and human food chain cycle, eventually leading to poisoning incidents; if on which a fire, will release a large number of dioxins and other harmful gases, a serious threat to human health.
Municipal Environmental Protection Bureau said the expert, "e-waste" in no way inferior to the harm garbage. On the one hand, and accumulated a large number of e-waste polluted the soil, rivers, groundwater, air, endangering human health; the other hand, a large number of electronic products for the mining of mineral resources production, lead to geological disasters continue to occur, mines and mineral resources, damage to the environment The growing shortage triggering resource-exhausted cities and other issues, but a lot of accumulation of electronic waste has a serious waste of resources.
