Low mercury is harmful mercury-free batteries

Recycling of waste and mercury-free batteries need not be treated separately, with the landfilling of waste? You Fuxi fifth grader Bo-Nien Chen yourself experiments to refute this opinion. The fifth group sponsored by the Nanjing Municipal Youth Science Small Doctor “the activity of small argument took place yesterday, activities, children had to write a much deeper conception of small papers.

Danger waste battery “negligible”?

Bo-Nien Chen recalled that the teacher in science class, said: No. 1, a cell to rot on the ground can make 1 square meter of land permanent loss of use value and a stack of coins allows 600 tons of water contamination. Therefore, he always thought that the batteries on the environment great harm.

But beware, when he read the newspaper, as many experts believe that the environmental risks of waste batteries is very unlikely, and even by authorities, recycling waste and mercury-free batteries need not be treated separately, with the landfilling of household waste. For such advice, Bo-Nien Chen does not agree with, and doing experiments to disprove. “I want to waste battery on studies of germinating seeds, let more people know the dangers of batteries.

The experimental data of mercury free batteries is harmful

Chen Bo, discovered through experiments in water rates of germination of mung bean seeds was 100% in a marked “low in mercury, zinc-manganese” batteries leaching solution in the germination rate mung bean seeds was 0 in a marked “the use of mercury and cadmium, 0″ leach solution of the battery in the germination of mung bean seeds was 100%, but later than the ‘water for the germination of seeds and germination of seeds after the cessation of growth, the final mold and necrosis. We can conclude that: low-mercury and mercury batteries scrap free on seed germination of mung beans and growth of these two dangers.

With experience and ask the teacher to find relevant information, Bo-Nien Chen that any exaggeration or reduce the hazards of batteries are not scientific claims. “We are the hazards of waste batteries have some understanding, but it is still quite positive.”
