Why are so many people still using mercury-containing batteries when they are so harmful?

Resolution:

For a long time, China has been producing dry cell batteries with the addition of a toxic substance - mercury or mercury compounds. The mercury content in our alkaline dry cell batteries reaches 1 to 5%, and 0.025% for neutral dry cell batteries, and the nation's annual mercury used in the production of dry cell batteries reaches dozens of tons.

Mercury is commonly known as "mercury". Mercury and mercury compounds are toxic, scientists have found that mercury has obvious neurotoxicity, in addition to the endocrine system, the immune system also has a negative impact. 1950s in Japan shocked the world's public health disease - Minamata disease, is due to mercury pollution.

More than 40 years ago, in Minamata, a coastal town in the southern part of Japan's Kyushu region, a strange disease appeared among local residents. Patients began to slur their speech, unsteady gait, paralyzed limbs, and finally, their whole body spasmed, mentally deranged, and died in agonizing pain. Later on, more and more people contracted the disease, and even cats and seabirds showed the same symptoms. Later, medical workers found toxic methylmercury from the bodies of the dead and sea fish, proving that people were poisoned by eating contaminated fish. After investigation, it turned out to be the local Japanese nitrogen fertilizer industrial company discharged mercury-containing wastewater to Minamata Bay all year round, so that the sea water was contaminated by mercury, and the locally fished seafood contained high concentrations of methylmercury.

In order to restore the ecological environment of Minamata Bay, Japan *** spent 14 years and invested 48.5 billion yen to remove all the mercury-containing sediment in Minamata Bay by digging 4 meters deep. At the same time, a quarantine net was set up at the entrance to Minamata Bay, and all contaminated fish in the bay were caught and landfilled. Masazumi Yoshii, the mayor of Minamata City, Japan, who witnessed the outbreak of Minamata disease, said with emotion: "After nearly half a century of unremitting efforts, we have finally emerged from the shadow of Minamata disease and are building a new Minamata City. I hope that the whole world will learn the lesson of Minamata disease in Japan and get rid of foolish production methods and promote civilized production methods."

It is understood that mercury-containing batteries have been eliminated in developed countries, and dry-cell batteries are mercury-free or low-mercury. In the Sino-Japanese Friendship Environmental Protection Center as a consultant to the Japanese experts Koyanagi Hideaki said that Japan is now the production and use of dry cell batteries are mercury-free, due to non-mercury, waste batteries on the environment is greatly reduced, the landfill disposal costs have also been reduced.

China from January 1 this year, also began the implementation of low mercury and mercury-free dry batteries, the arrival of the new century, the green battery finally came into the lives of the Chinese people. However, according to the reporter's understanding, most consumers in China on waste battery pollution is not too much, people tend to buy batteries have a great deal of arbitrariness, and did not put whether to meet environmental standards in the first place. For battery manufacturers, the production of environmentally friendly batteries, the need to improve the process equipment and raw material formulations, which undoubtedly increase capital investment and production costs, enterprises are not very willing. At present, some companies on the battery "limit mercury regulations" indifference, press the military.

How to advocate green consumerism in favor of environmental protection? How to promote enterprises to produce green products conducive to environmental protection? The reporter interviewed Professor Ye Wenhu of Peking University Environmental Science Center. He said that the choice of what kind of consumer goods determines the way people consume, and the way the public consumes is a sign of the degree of social civilization. Through publicity and education, the public should be advocated to choose a new way of consumption in line with the concept of sustainable development, and buy green products that are conducive to environmental protection, and the choice of consumers will push producers to improve their products. In addition, manufacturers should be actively advocated to produce environmentally friendly products. What kind of products enterprises use *** consumption, which involves the quality of entrepreneurs and the image of enterprises. However, only these two points are far from enough, because from the public's consumer psychology, the general pursuit of cheap and good quality, environmental protection is not a very important factor; from the operation of the enterprise, to make money is the first, environmental protection is not being considered the primary factor. Therefore, it is necessary for *** to step in and use economic, legal and administrative means to promote the production methods of enterprises and the public's consumption methods to meet the requirements of environmental protection. In the *** behavior, market behavior (or enterprise behavior) and public behavior of the three human social behavior, *** behavior is in a dominant position.
