In order to protect the environment, how to deal with allegations of batteries is the most reasonable ?

Firstly, the battery components: batteries, rechargeable battery components: the skin of zinc (metal) carbon rod, mercury compounds, sulfuric acid, the lid of copper, based batteries lead compounds. For example, the first composition of the zinc-manganese residues, with a weight of 70 grams of carbon rod which 5.2 grams, 7.0 grams of skin of zinc, manganese powder, 25 grams, 0, 5 grams of copper lid and another 32 grams. Second, the danger of batteries: the hazards of waste batteries mainly concentrated in a small amount of heavy metals contained in them, such as lead, mercury, cadmium. These toxic substances enter the body through various means long term savings is difficult to exclude damage to the nervous system, bone and hematopoietic function, and even cancer. Lead: the nervous system (nerve weakness, numbness), gastrointestinal tract (dyspepsia, abdominal pain), blood poisoning and other diseases. Mercury: The change of mental state is one of the main symptoms of mercury poisoning. The pulse rate, muscle tremors, mouth and digestive system diseases. Cadmium, Manganese: Central nervous system hazards. Third, the batteries pollute the environment as follows: the composition of these batteries in the course material was sealed inside the battery case does not affect the environment. However, after long-term mechanical wear and corrosion, causing the internal pH and other heavy metals and filtered in the soil or water, people will be through a variety of ways to enter the food chain . Are summarized below: pool microbial cultures, animals, human neural circuitry of dust deposition of other digestive diseases biological sources of intake of plant foods heavy metals from the environment may be through the chain biomagnification step food in the tens of thousands of higher organisms enrichment, and then enter the human body through food, resulting in savings of some organs of chronic intoxication. The water in Japan (one more NG) disease is a typical case of mercury poisoning. Fourth, the performance of other hazardous waste batteries, the world's main landfill waste disposal, composting and incineration of three ways, mixed solid waste from used batteries in the role of pollution in the three processes is reflected in: landfill: Waste of the role of heavy metal contamination of the battery with water and soil leachate. Incineration of waste batteries at high temperature, corrosive, some volatile heavy metals in fly ash from incineration, causing air pollution, accumulation of incineration bottom of heavy metals, which produce ash contamination. Composting: heavy metal content of battery scrap high, resulting in a lower quality compost. Reuse: the general use of reflective metal fire method, easy to understand, but the recovery process, although only 82%, the remaining lead in the form of gas and dust appear, while the melting process of sulfur dioxide air is introduced, causing secondary pollution directly the functioning of the health hazards of workers. A 1, to rot mercury battery on the ground, can make a square meter of land completely lost the value of agricultural use, a button battery can make 600 tons of drinking water. They represent the greatest threat to the natural environment of the five substances in the battery contains mercury, cadmium, lead, three. Battery consumption in China is a big country, battery production in China in 2001 was 14 billion sales, accounting for the world total battery 1/3. If we all use batteries that contain mercury, which pose a threat to our survival. The environmental cell batteries are mercury or low mercury, which can greatly reduce the use of batteries to water, soil contamination, which caused the damage to human health to a minimum. Currently, the products of domestic and international battery market monomer must be labeled mercury (mercury content in batteries annotation methods other than the Environmental Protection internal battery manufacturers mark, " low mercury "," mercury free "or" Mercury is 0 "" Mercury is 0 "and in other ways.) consumers to buy the battery, just look at the mercury content of batteries, you can know that batteries are not environment. A battery of 600 tons of pollution of the water! Face increasing waste batteries, some experts speak: the potential hazards of waste batteries can not be ignored, making the society's attention a matter of urgency and concern. It is now almost a day in the social life is inseparable from the battery. China's annual consumption of the battery of a 7.0 million ~ 8 million, per capita consumption of 5-6 batteries a year. The battery is most commonly used pagers, cell phones, pocket radio, walkman, remote control and so on. Just look, for example, across the country about 40 million pager users about a year at least one user to use sixty-seven battery consumption of 250 million dollars a year or so. State Environmental Protection Administration of Science, Technology and relevant persons with the battery type, production and use continues to grow, the number and type of batteries has also increased. Used batteries contain mercury, lead, cadmium, nickel and other heavy metals and acid and alkaline electrolyte solution, and the ecological environment in the human body has different degrees of damage. It is understood that one of the ecological environment on human health and the most harmful, the checklist included in the hazardous waste batteries are mercury-containing batteries, mercury oxide batteries, especially batteries, lead-acid batteries, cadmium, nickel-cadmium mainly. Relevant data show that a battery One rot on the ground, you can have a square meter of soil permanent loss of use value, a button battery 600 tons of water may be contaminated drinking water is equivalent to the amount of one's life. The greatest threat to the natural environment of various substances in the battery contains mercury, lead, cadmium and other household waste if mixed with filling batteries, or mercury leaking material discarded and heavy metals leaching on the ground, pollute groundwater and then into the fish, crops, destruction of human living conditions, indirect threat to human health. Once the absorption of these heavy metals in the body after the symptoms appear? Experts say mercury is a highly toxic heavy metal, very destructive to the human central nervous system, the 50 of the last century occurred in Japan surprised the world of Minamata disease is due to mercury contamination. Currently China's production of alkaline batteries containing mercury content of mercury in 1% to 5%, the mercury content of 0.025% neutral dry China's consumption of mercury in battery production of several hundred tonnes each year at most. Cadmium in the human body can cause chronic poisoning, the primary disease is emphysema, osteomalacia, anemia, is likely to paralyze the body. The excretion of lead in the human body more difficult, which interferes with kidney function, reproductive function. Experts believe that pollution has a long life cycle due to the characteristics of the battery, concealment and the other, the potential damage is very serious, improper handling can cause secondary pollution. According to Dr. Yang Yifu, in the coastal province of China of some farmers in the recovery of lead acid batteries due to inadequate recycling, waste containing lead and spent sulfuric acid not only caused the poisoning, but can not grow local crops. Therefore, the classification of the battery to put inside the rubbish, or when it sends to develop more appropriate
