Low temperature volatilization of mercury is a highly toxic heavy metal. Many parts of the soil also contain trace amounts of mercury in the mercury mining, refining, processing of mercury-containing Acer aspire 4520 battery products, such as the confined measures are not sufficiently complete, the release of mercury into the air (steam) on the health of the operator a great influence.
Batteries may contain mercury, but because it is additive, its concentration rarely. Even the high-mercury batteries, mercury batteries in general are less than one-thousandth of the weight. China's battery industry with the annual amount of mercury, generally in line with a mercury-polyvinyl chloride, or alchemical Mercury, Lead and Zinc Mining and Dressing or high mercury emissions from waste water companies in the year a considerable amount of mercury. Since the battery consumption of the regional big, mercury used batteries into the garbage disposal system, after the environmental impact of chemical emissions than the previous one the impact of mercury-containing waste water is much smaller Moreover, the battery used in stainless steel or carbon steel made of the outer foreskin , effectively preventing the leakage of mercury. Therefore discarded used batteries scattered garbage in life, the harm is minimal objectively impossible like Minamata disease caused the harm. Minamata disease in Japan is the chemical industry for several decades to a large number of river discharge of mercury-containing waste water, the gradual accumulation of mercury in the downstream river system caused.
Mercury-containing batteries are being replaced by mercury-free battery
Of course, the mercury-containing waste Acer aspire 4520g battery batteries, after all, have a negative impact on the environment (even slightly). Thus, in the end of 1997, the State Economic and Trade Commission, China Light Industry Association and other nine departments have jointly issued a "restriction on the provisions of mercury batteries," learn from the experience of developed countries require domestic battery manufacturers to gradually reduce mercury content in batteries in 2002, the domestic sales of batteries to reach low mercury level in 2006 reached the level of mercury-free.
From a practical view of progress, domestic battery manufacturing industry in accordance with the basic "rule" requires the progressive reduction of mercury content in batteries. According to the China Battery Industry Association, data provided by Chinese battery output to 180 million, exports about 10 billion, the domestic annual consumption of about 8 billion, the basic standards have reached a low of mercury (mercury content less than 0.025% by weight batteries) . Of these, about 2 billion to mercury-free standards (mercury battery weight of less than 0.001%).
Professor Nie finally stressed that there was no waste at home and abroad as the battery causing serious air pollution reports or scientific information, the used batteries Acer aspire 4710 battery pollute the environment argument is the lack of scientific basis, resulted in misleading the masses.
