DNA Electronic

The main source of pollution is the burning of plastics, in the long smelters for recovery of metals. All this is happening to hundreds of small, controlled electronic trash magnate, factory, scattered around the city. J.D. Peterson shines more light on the discussion. River in the city, classified as the most polluted area in southern China. A river in surface waters and in sediments contain high levels of copper, nickel, cadmium, lithium, mercury and arsenic. The program for the United Nations Environment Programme, said that China produces more than 2 million tons of electronic waste each year in the country (data for 2007), and comparable only to the U.S., which in turn produce these waste around 3 million tons. With the bulk of U.S.

electronic waste is exported to developing countries such as China, where imports of electronic waste is formally forbidden. More about half a million tonnes exported from other parts of e-waste are processed each year in this small town, as evidenced by the local authority. Authorities say most of the wastes that are imported into the city, trafficked from abroad (probably about 90%). Recently, Chinese doctors released a high-level data of biphenyl in blood samples of infants, children, workers engaged in processing electronic waste. In the 2008 study, produced by Chinese scientists found that in more than 80 percent of blood samples taken from babies in this town exceeding all standards in terms of lead, cadmium, chromium. The high chromium content leads to DNA damage. It leads to high mortality, low weight at birth and development. The chemicals contained in the flame retardant getting into the environment, affect the growth of diseases associated with cancer, thyroid gland, with the advent of memory problems, decreased sperm quality and reduce male potency. On these issues long suppressed because workers who come to this city were temporary. And keep track of their disease, and even more To confirm that these diseases are associated with environmental pollution has been quite difficult. It is only now beginning to take China at least some steps in this direction, developing national guidelines for the export and recycling of electronic waste.
