Waste mercury-free batteries do not have to be recycled and individually dealt with, can they land all with life garbage? Chen Bai year, the fifth grade of Youfu West Street, Into myself, refuted this point of view. The 5th Nanjing Youth "Science", hosted by the Municipal Committee, held a small paper in the event, and the children wrote a lot of enthusiasm. Waste batteries hazard "minimal"? Chen Bai, remembers that the teacher said in the science class: one-piece battery is rotten in the ground, which can make the 1 square meter soil permanently use value; a button battery can cause 600 tons of water pollution.
Therefore, he has always believed that the waste battery has a great harm to the environment. But when he was looking at the newspaper, he found that some experts believe that the hazard of the waste battery is minimal, and even officials say that waste-free batteries do not have to recycle and deal with them, can landfill with domestic garbage. For such views, Chen Bai is not recognized, and by doing experiments.
"I want to learn about seed germination through waste batteries, let more people understand the harm of waste batteries. "Experiment proves that the mercury-free battery is also harmful to Chen Bai years: the germination rate of mung bean seeds in the clear water is 100%, in a certain green bean seed germination rate in the leaching liquid labeled" low mercury zinc manganese ", in a certain The germination rate of mung bean seeds in the battery leaching solution labeled "mercury cadmium 0" is 100%, but the seeds in the cleans are late, and the seed germination will stop growth, and finally mold, necrosis. This can be concluded that low mercury and mercury-free useful batteries are harmful to the germination and growth of mung bean seeds.
Through experiments, please ask the teacher, find relevant information, Chen Bai believes that any statement that exaggerated or shrinking the harmful battery is unscientific. "We have a certain understanding of the hazards of used batteries, but there is not active on action. "The" Science Little Dr.
"Organizing Committee screened 74 outstanding papers, which covers multiple disciplines such as society, life, and creatures. It is reported that the players who have a good performance in this small papers and the reply will receive the honorary title of the 5th Nanjing Juvenile "Science Little Dr.".
