high-mercury batteries

Low temperature volatilization of mercury is a toxic heavy metal more. The soil in many places also contain traces of mercury, the mercury mining, refining, processing of mercury-containing products, such as confined measures are not sufficiently complete, the release of mercury into the air (steam) on the operator's health greatly.

Batteries may contain mercury, but because it is additive, which contain only small amounts. Even high-mercury batteries such as Toshiba PA2487U Battery, Toshiba PA3107U-1BRS Battery, Toshiba PA3383U-1BRS Battery, Toshiba PA3384U-1BRS Battery, Toshiba PA3285U-1BRS Battery, Toshiba PA3191U-1BRS Battery, Toshiba PA3166U-1BRS Battery, Toshiba PA3331U-1BRS Battery, Toshiba PA3098U-1BRS Battery, Toshiba PA3084U-1BRS Battery, mercury batteries are generally less than one thousandth of the weight. China's battery industry's use of mercury throughout the year, broadly in line with a mercury chloride or mercury alchemists, or high-mercury zinc Mining companies in mercury emissions from wastewater quite. As the battery consumption of a large area, mercury-containing waste disposal system after the battery into the life, impact on the environment of a chemical industry emissions than the aforementioned impact of mercury waste is much smaller Moreover, the use of stainless steel or carbon batteries do Wrapper effectively prevent the leakage of mercury. Therefore discarded used batteries scattered in the solid waste, the harm is minimal, can not objectively like Minamata disease caused the harm. Minamata disease in Japan is the chemical enterprise for several decades to a large number of river discharge wastewater containing mercury, mercury in the downstream river system caused by the gradual accumulation.

Of course, the mercury-containing waste batteries, after all, have a negative impact on the environment (even minor). Thus, in the end of 1997, the State Economic and Trade Commission, China Light Industry Association and other 9 departments jointly issued a "restriction on the mercury content of the rule", borrowing from the experience, demands of domestic battery manufacturers to gradually reduce the mercury content, in 2002 China sales of batteries to reach low mercury levels, mercury levels reached in 2006.

Progress from the actual point of view, in accordance with domestic battery manufacturing basic "rule" requires the gradual reduction in mercury content. According to the China Battery Industry Association data, our battery output to 180 million, exports about 10 billion, the domestic consumption of about 8 billion years, the basic standards have reached a low of mercury (mercury content less than 0.025% of battery weight) . About 2 billion to the standard mercury (mercury content of less than 0.001% of battery weight).

Professor Nie final stress, as used batteries at home and abroad caused no serious pollution reports or research data, the used batteries pollute the environment argument is the lack of scientific basis, resulted in misleading the masses.
