Anonymous users2024-02-15Batteries contain three of the five substances that pose the greatest threat to the natural environment: mercury, lead, and cadmium.
Heavy metals refer to metals with a specific gravity greater than 4 or 5, and there are about 45 kinds, such as copper, lead, zinc, iron, cobalt, nickel, vanadium, niobium, tantalum, titanium, manganese, cadmium, mercury, tungsten, molybdenum, gold, silver, etc. Although heavy metals such as manganese, copper, and zinc are trace elements needed for life activities, most of the heavy metals such as mercury, lead, cadmium, etc., are not necessary for life activities, and all heavy metals are toxic to the human body if they exceed a certain concentration.
The biggest threats to the natural environment in batteries are lead, mercury, and cadmium.

Anonymous users2024-02-14Answer]: There are roughly three ways to dispose of waste batteries in the world: solidification and deep burial, storage in waste mines, and poor utilization.
Among them, the utilization method of waste battery is divided into heat treatment, wet treatment and vacuum heat treatment. Item B error. Therefore, choose Dust Qi B.

Anonymous users2024-02-13Answer]: B waste batteries are discarded in the environment in large quantities, and the acid and alkali electrolyte solutions in them will affect the pH of the soil and water system, making the soil and water system acidic or alkaline, and heavy metals such as mercury and cadmium are absorbed by the organisms and enter the human food chain through various paths and paths, and accumulate in the human body, making the human body teratogenic or mutating, and even leading to death. There are roughly three ways to dispose of used batteries:
Solid destruction is deeply buried, stored in abandoned mines, and utilized. Item B said that the auspicious method of the fiber was wrong, and he was elected.

Anonymous users2024-02-10Summary. Dear dear, it's a pleasure to answer your <>
The graphite electrodes in the battery contain lead and chromium, while the zinc oxide electrodes contain zinc and contain other elements such as cadmium, silver, mercury, etc. In discarded batteries, these elements are released, and as the battery corrodes, it gradually seeps into the surrounding soil and water, resulting in soil and water pollution. These heavy metals and harmful chemicals can accumulate in soil and groundwater, affecting water quality and threatening the health of ecosystems.
When animals or humans ingest contaminated soil or water, these harmful substances can enter their bodies and cause adverse health effects. <>
Starting with the analysis of battery structure, why throwing away discarded batteries can cause soil and water pollution.

Pollution from discarded batteries can also cause harm to plants. The released heavy metals can be absorbed by plants, resulting in an increase in the plant's cell dixing, which reduces plant growth and production. This has a negative impact on the environment and humans, as plants are heavy grinders for food and oxygen.

Anonymous users2024-02-09Answer: Mercury is what we commonly call "mercury". Scientists have found that mercury has obvious neurotoxicity, in addition to adverse effects on the endocrine system, immune system, etc. In the 50s of the 20th century, the world-shaking pollution disease——— Minamata and Blind Circle Disease that occurred in Japan was caused by mercury pollution.
Sustainable development.
Since the middle of this century, social, economic and political issues such as resources, environment, and population have become increasingly acute and globalized, and the so-called "human dilemma" has attracted more and more researchers. Among them, the results of the research of the Club of Rome are the most remarkable. Founded in April 1968, the Club of Rome is a small group of renowned scientists, economists and sociologists. >>>More

The influence of the natural environment on the ancient Egyptian civilization was decisive, because under the specific social environment at that time, people's understanding of the natural environment was not comprehensive enough, and they believed that most of the wind, rain, thunder and lightning produced in nature came from their most revered gods, forming a certain mythology.
